Title: Any Shade Tree Mechanics Out There?
Post by: branch37 on August 26, 2016, 08:39:48 PM
I have a '67 F100 pickup with a 351W V8.  The pickup has been sitting unused, in the open for nearly 10 years.  The interior is a wreck and needs a complete re working.  The paint job is also pretty much gone, but the body, frame, and engine are all in decent condition.  So far I have replaced the carburetor, breather, fuel pump and filter, shocks (front and rear), front wheel bearings, and the engine oil and filter.  Now to my problem.

I have little to no experience adjusting carburetors.  I have swapped them out and rebuilt them before, but they have always ran smooth afterwards.  This engine runs great at idle, but will not accelerate once in gear.  It is a 3 speed automatic BTW.  It also wont shift gears on its own but we will get to that later.  The only way I know how to describe it is that it seems like it isnt getting fuel.  On flat ground, it will move fine at idle speed, but once i accelerate it sputters and will die unless i take my foot off the gas.  Any advice?

Can you run up the RPMs when in neutral? Shifting and such could be vacume issues as well as accelerating in gear.

Could be several things. I would start checking vacuum lines. They are probably dry rotted and cracked. The one leading to the transmission would also cause it to not shift up.

If you find any dried and cracked then replace them all. If that is the problem you will find that the idle will have to be adjusted up after repair.

What you describe sounds just like this scenario as it will run when idle but when you start dumping fuel into it the fuel air ratio is too far off.

I can but i still get a little sputter when accelerating gradually.  If i floor it it runs up fine.

I have not checked the vacuum lines going to the transmission, but the one going to the carb and the big one coming out of the head is fine.  I know the gears do work because i can start in first then shift manually into second and it will work, it just wont shift up into third.  If i then shift back into drive and slow down it does downshift like it should.

In Park when you give a quick jab to the gas pedal does it stall?

Second, is the 351 a motor replacement?  The 351w was not an option that year if I remember right.

Could be a blockage or a nest in the exhaust pipe, also.  A blocked exhaust pipe will act like a governor, restricting air flow below a certain volume.  I had a catalytic converter break apart in the wife's car, and it had the same symptoms as yours.  Purred like a kitten at idle, but I couldn't get it above 2000 rpm.  On the road, it had trouble getting into 2nd gear.

yes.  If I go all the way to the floor it runs up fine, but if i jab it it will stall.

Yes it is.  My dad put the motor in it sometime in the late 70s or 80s.  You can go about 20 miles on a tank of gas.

There could be so many things wrong it would be a waste of time to isolate on a bulletin board.


Could be as simple as choke that is stuck, to a leaking Gasket on the carburetor. Timing, and everything that has been listed.  Make a list and work them one at a time.

Else you will go crazy with a scattershot attempt to fix it.  Eliminate the problems one at a time the best way to isolate it and only spend on parts you definitely need.


Otherwise you may purchase parts that aren't needed.

Yup listen to Hajo!

 I would get the motor running first,then deal with the tranny after. Been sitting long,likely needs new fluid and filter for trans anyways.

 Something silly as the PCV valve could be plugged but not being able to be there it's all just guess work and as Hajo said that could lead to you getting things you just didnt need!

As far as these things go the choke is working properly, gaskets on the carb are all brand new and not leaking, from what I can tell the timing is good.  I'm starting to think it's just the carb needing adjusting.  I fiddled around with the idle screws a little this morning and it seems to be running better.  Still not where I want it but it is better.  I can now drive down the street and back without it dying, but i'm still stuck in first gear.

It could even be a bad accelerator pump on the new carb. It should spritz some gas into the Venturi when you quickly press the pedal.

Some many things it could be.

you can take some starter fluid and spray it by your vacuum lines, spray just a little and see if your rpms go up.( need air cleaner on and such) vacuum leak if the rpms go up. All good suggestions. I have a68 ford f100 out back I did same thing with. I rebuilt a 351 W and put it in it. Running gear is great rest of truck is rust. Think I got about 10 miles to the gallon the truck is low geared.
Sitting so long moisture in the gas tank.

There you go,  accelerator pump problem.  Check the linkage first.  Look inside the barrels and see if you get a squirt of fuel.

air to fuel mixture set on the carb?  To much of one and not enough of the other engine won't run properly. Sounds like when you step on the gas the engine starts to die.  Could be to much fuel when accelerating and not enough air.

I'm not familiar with that carb but there should be two screws one for air and one for fuel.  Check there.  When you spike the accelerator it should be immediate response to higher revs then lower revs.  To much carburetor?  Check.

Idle should be smooth in neutral.  You can work the throttle linkage while adjusting mixture by hand.  Should tell you something if that is the problem area.

Again a lot to check.  Remember also that a vehicle that sat that long ruins the gaskets.  They dry out.  You said you placed a new carb gasket that sits between the intake and the carb.  Check for leaks there.  Check vacuum lines also.

Rubber dries out in a hurry.  Sat for 10 years they are probably dry rotted.  As shuffler and Frenchy said be sure to check the vacuum lines.  eliminate the possibilities one by one.  Be patient and don't throw the tools.  May take awhile.

Branch, if you have a vacuum gauge hook it up to a non ported source at the base of the carb. You can tell a lot of what is going on by the actions of the gauge. There is a pretty good illustration here: http://www.onallcylinders.com/2016/03/31/vac-visual-quick-guide-vacuum-gauge-readings/

Also check that the mechanical/vacuum advance in the distributor is working properly.

I did some tweaking with it yesterday evening and I think I've pretty much started getting it worked out. The fuel/air adjustment screws were screwed almost all the way out. That's how it came from the factory. I screwed them all the way in until it wouldnt run at all and started backing them out until it ran. I'm no longer stalling when i try to accelerate, but it is idling slow and stalls when stopped at stop signs and such. Further adjustments today. I also checked for gasket leaks and found none. Nobody could get the right gasket that goes between the carb and the manifold so i made one and it is working. I didn't find any vacuum leaks, but I have only checked the few lines on top of the engine.

That's where I'm at right now. Transmission still isnt cooperating. The main issue is low transmission fluid, but nobody has any records of what kind of fluid it takes. Thats what im working on today.

Post by: morfiend on August 29, 2016, 08:18:51 AM
It should use FoMoc transmission fluid!

  Low fluid will cause it to not shift,I would drop trans pan and change filter and check for metal,an old speaker magnet works great to pick up any metal that might be in the pan,if you find lots you may need a complete transmission service.

  Yes I believe so,it's likely a C4 trans,though it could be an FMX....hope not.... I would use a fluid rated for Ford trans,dont use dextron!

  Grab a filter kit while you're at it,check pan for filings as I said,a small amount is usual,if the magnet is covered in fillings,well you may need to have it serviced,unless you're willing to tear it apart yourself..... not for the faint of heart!


  If you do tear into it,cleanliness is top priority!!!  The valve body has many channels and passages,the slightest bit of dirt can cause untold problems.


  Have fun....... :devil

Update.

Transmission fluid and filter changed. Now it shifts gears like it should only it shifts at a higher RPM than I would like.

I never did get it running right.  I adjusted the screws on the carb for over an hour with only slight improvement before giving up and deciding to test the shifting on the highway. I pulled onto the highway and put my foot down. It took off but only went up to about 4000 RPM. I let off the gas slightly to see if it would shift and it did, but wouldn't go any faster. On a whim I closed the choke. It took off like a scalded rat. I hit 75 mph in about 1/8 mile. I opened the choke and lost a ton of power. That says to me a vacuum leak. Anybody know how many vacuum lines are on this flavor motor?  There is a connection on the lower back of the carb near the mechanical choke that looks like a vacuum connection but there's no line. I'll post a picture later. And I'll get a picture of the carb tomorrow.

If that connects to the carb spacer plate, it's a EGR valve... most likely.

On a 4 barrel carb, do you know if the secondary's are opening properly, next time in the garage with the air cleaner off open it up and watch in the carb the secondary flap open, the old holly's I had sometimes had a vacuum operated secondary but also some had a mechanical secondary controlled by the linkage.  Sounds like by hitting the choke your feeding it more gas.  I know sounds to easy but you never know.

Yes the mixture doesn't seem right, have you had the carb apart recently? passageways are clean and open, float needle is allowing gas to flow?  on some carbs when its running you can see the gas spraying into the manifold when you look down the carb.

Did you say that you made your own carb to manifold gasket?  Did you have the old one for a template, if you were to look at the bottom of the carb could you have covered up a port that should be open, is there a vacuum line that goes from the manifold to a modulator on the transmission, that would account for both issues?

Post by: SIK1 on August 30, 2016, 01:10:35 PM
The fact that the truck regains power when you close the choke tells me that you do have a vacuum leak. That is what you should focus on first. As long as you have a vacuum leak you will never get the mixture set properly.

Looking at the pic of the connection coming from the circular thing. I agree with xtrepid it looks like it is part of the EGR system. The second pic is hard to see but that does look like it is located in the intake port. I forgot what era you said the engine was from but if it's from the eighties there are several sub-systems associated with the smog system that can be causing you problems if they are not properly disabled.

A rig from the trucks generation would only have a vacuum line for the distributor advance, and pcv valve, if it had one. One of the great things about a truck from that era is the simplicity. Try to cap off and plug the stuff that's not being used .

I had a '68 short bed F100 in high school that I put a 390 in. It was scary quick from stop light to stop light, because of the 4:11 gears and the low gearing of the NP 435 trans. Unfortunately it topped out at about 80 mph because of the gearing and the fact that the truck is about as aerodynamic as a billboard.

You need to make sure the metal line going down to the transmission is transmitting vacuum to the vacuum modulator.
Title: Re: Any Shade Tree Mechanics Out There?
Post by: WEZEL on August 30, 2016, 06:44:17 PM
The vacuum valve next to the distributor is a thematic valve and is in the cooling system, it closes off or applies vacuum to components as engine temp goes up.  My guess it was for the hot air/ cold air doors that were in the stock air cleaner assembly, ignore it not your problem.

The EGR valve could be stuck slightly open and causing the concern[internal vacuum leak] Take it off and either make a block off plate and add new gasket for it , or take it off and blow trough the side without the pintel in it, if you can blow trough it it's either stuck open or leaking past the shaft.

 Me personally I would just make a block off plate for it and call it a day.

That truck running points or  duraspark ignition? Cant tell from the pics.

Cap looks kind of dirty and the inside might be worse. A timing light should be used to check timing, probably can rent one from autozone or someplace like that,  have to make sure the basics are ok to move on to the next step in daig.

A stretched timing chain will mess the running of the motor also,


As for the trans[dont know what you got]  but most likely there should be a vacuum line running down to a vacuum  modulator valve bolted to the case, make sure you have engine vacuum to it and it is not chewed up by some critter.

Ok I was going to post pictures but I can't log into the bbs on my pc for some reason.

First interesting development. I discovered that 351W parts fit very well on a Ford 360. Turns out I have a 360. Not a 351w like I thought. I found this out while looking for valve cover gaskets.

Now the second, and potentially bad development. I was driving during my lunch break I fired it up and on the first crank heard a bang rattle rattle rattle. 2 stuck valves and bent push rods. No idea why the valves would decide to stick now. I can hit them with a rubber hammer and they will free up but will be stuck again 10 minutes or so later. The other way I discovered that I have a 360 is that 351w push rods are too short.

Well you don't have to worry about the vacuum leak now.  :bolt:

The valve probably stuck because the truck didn't get regular oil changes and then sat for many years. Are the two stuck valves on the same cylinder or on different cylinders? Sticky valves in an FE series is a scary proposition. They can and will eat valves. I've killed two, both high mileage 390s. Both hit a piston with the intake valve. One was a long way from home.
I actually have a low mileage 390 sitting in an old f250 out back. That's the last truck I've owned with spark plugs.
Be forewarned if you decide to pull the heads the cast iron intake manifold weighs a ton. Get someone to help or use a cherry picker. The heads aren't exactly light either.

Update:

Now firing on all 8 cylinders. Still having the previous problem. A reasonably competent mechanic and myself looked over the engine and transmission for hours today and could not find a vacuum leak. I'm starting to think the carb is wrong. We adjusted it every way we could with no results.

It still sounds like an exhaust back pressure thing to me.

If the exhaust was blocked would it run with the choke closed?

I quit replying when I saw what he was up against. This is a pure hands on venture. One needs to have the vehicle available to hear and see what it is doing to troubleshoot. We are just making best guesses otherwise.

Running the engine could be causing damage we can't detect on the boards.

Check the ERG valve,they are known to go bad,build up carbon and if they sat for awhile it's likely stuck! It's a silly thing anyways,meant to pump exhaust gas back into engine through intake man to supposedly help with pollution...... :noid

  I had an early crown vic and it had a 302 that just wouldnt run unless the EGR functioned properly,of course it had an early variable venturi carb that was a piece of well you know!


  If the egr is stuck open it could cause the lean condition,which closing the choke would help.Either block it off or make sure it works!

Could I take the carb off and remove the entire EGR valve plate and close off the hole in the manifold for the exhaust gas?

:airplane: I had a 1946 Ford at one time in early 50's and it was doing same thing! A "valve" job cured all the engine problems. Before the valve job, it would only run at idle or wide open, but not in between. Was very interesting trying to "date" in this thing! Girl sitting by me and floor shift knob and me having to constantly change gears, well, I got "slapped" more than once!

  Ya I beleive Wezel already pointed that out!


  That said,if you have valves that are stuck/sticking I wouldnt run the engine until you resolve that issue. Since you're in so deep,I'd pull the intake and heads,ya it means new gaskets etc. but it beats bending a valve and possibly breaking a piston or 2!!!


  I would start with a good engine degrease,powerwash the motor and then start the tear down. Be sure to bag the distributor,I always used a large plastic baggy of the freezer type to help keep most of the water out.


  Have fun!

Also that engine has sat a long time, its mechanical fuel pump and how is the fuel pressure? Your seals and gaskets will no be that great. also the oil prolly not so good, the oil sump has a screen and if you get it running I would change the oil couple times. If you get sludge and crap on the sump screen it will restrict the oil flow. Now you have bent pushrods, if it were me and which I have a cherry picker and engine stand, I would just remove the engine, but then that's me. Lots of working room in those old fords.
I don't know how your equipped with tools.
If the exhaust was plugged it would run for awhile then quit.
Even if you have it running on all 8 cylinders the valve issue would have me very concerned. Specially if that is a interference engine.(sounds like it is)
The heads and intake are heavy, I was setting a head down and my foot hit a bump in the concrete I slipped alittle and caught my thumb. So I put a bandage on and finished up what I was doing and cleaned up for the night. Then I went to the hospital and they cleaned, stuffed the meat and stuff back in my thumb and sewed it up couple stiches.

Also thinking about it, might want to make sure your fuel lines are clear. Truck been sitting maybe some crap , rust what have you may entered the fuel line. On a harbor boat I once worked on it had 3   6-71 detroits. one of them fuel problems. Ended up being the spray top from a spray paint can or either can, how the heck it would of got in the fuel tank who knows, but it entered the fuel line and created a partial blockage.

Dont know about derived, they dont have much in common other than one replaces the other, are you thinking about the C3 and the A4LD, basically the same  with the addition of a clutch pack and band.
Title: Re: Any Shade Tree Mechanics Out There?
Post by: icepac on September 06, 2016, 11:26:16 PM
The planetary gearset is the same.......or course the case of the transmission and other parts will be different when adding a .67 overdrive 4th gear.

The ratios are the same because they both use the Ravigneaux planetary gearset.

Much of the actuation of clutches is the same hardware.

When we replaced all the valve springs in the 2006 to 2008 lexus 3.5 V6s and V8s (rear drive direct injected), I saw the recall notice and told the parts department to order a bunch of keepers.

They didn't order them and we had a bunch of cars down because of it.

It still happens at toyota and lexus.........they just never stock a 15 cent part that ends up costing them a bunch of money in rental or loaner cars.

So I'm throwing the idea around of replacing my intake manifold. There's not really anything wrong with the one I have except one of the bolt holes is chipped where somebody tightened it too tight and cracked the cast iron. The crack doesn't go into the bolt hole so no leaks. I want to change it simply because it weighs a damn ton and is ugly as hell. My problem is that I can't find one for a ford FE 360 that will take a 2 barrel carb. I would rather not spend around $400 on the manifold and have to buy a 4 barrel carb. Any suggestions?

Branch, I'm not sure that an aluminum 2bbl FE manifold was ever produced. The best solution would be to re-install the manifold you have and never ever remove it again. Of course if you really want an aluminum manifold. They use to make an adapter that would let you run a 2bbl carb on a 4bbl manifold.

Honestly I think your very fortunate with availability and reasonable pricing of aluminum manifolds for the FE engines now. Especially considering that an FE engine hasn't been produced in forty years. When I was in high school and playing with FE's I ended up buying an Offy manifold from a wrecking yard. I managed to get the manifold for a price I could afford because it had a piece missing from the valve cover rail. Lucky for me I know a guy that is an artist with a welder.
