This is what I've had the pleasure of working on all week. Now THAT'S a cylinder head. If I had been thinking I would have taken a picture of the piston too. IIRC the Piston rod is 4 feet long and 1.750 inches in diameter.

Well, that is outside of my experience.. :salute
What is it?

I second that question.

A cylinder head off of a gas compressor. Very similar to the piston cylinders in your everyday car only much much bigger.

Huh I thought it was some wacky old airplane engine. :uhoh
I play with diesel engines and this is what you don't want to see a Head look like..................

That kinda depends on whether you are paying fix it, or being paid to fix it. :D

Oops.
Where do you work, by the way?

GM dealer in Ocean County NJ. Most Duramax engines last a long time but like anything it's how you take care of them.
Sadly GM doesn't make Medium Duty Trucks anymore and working mostly on the smaller trucks now. :frown:
-
pretty much everything pictured is out of my territory.
my current nightmare, is a viper truck that came in with the power steering pressure hose leaking. the section between the pump, and the fan. yes, the fan is driven by the power steering system.
anyway, it was leaking at an o-ring. can't replace the o-ring, 'cause the hose can't be disassembled. ordered a new hose and fittings. no problem, right? wrong. it lasted a week, and blew the hose off. then it did it a couple more times. so far, i haven't found why, but working on that.

It seems you are not alone. A problem with oem parts perhaps. You may need to go aftermarket.

You mentioned Diesel, so I was curious.
My Step-father is the service manager at a local International Trucks dealer.
He is always telling me the importance of taking care of routine maintenence on Diesel engines to get the most lifetime miles out of them.

My water district just bought me a 2013 GMC 3/4 ton duramax, I really don't do a lot of highway driving mostly just puttering around the backroads looking for leaks and such, but we bought it to pull my mini trackhoe. My question is, they said at the dealer you sometime have to "blow out" some sort of diesel particulate filter, is my slow rolling around not good for this duramax, or does my monthly trip to the health department, (which is about a 80 mile round trip on the highway) considered blowing it out? The dealership said I shouldn't worry about it, but my luck is not good and I can see this truck crapping out because of something I'm not familiar with.

thanks for that link!! i gotta join that forum now, and see what that one guy pm'd the op.....maybe it'll help me cure this problem. in the meantime, i'm on the phone to napa to see if they can make me a one piece hose for this.....

These new emissions on diesels are really getting complex. They started with a particulate filter in 2008 that traps soot in a honeycomb structure where the muffler used to be, then whats called regeneration burns the soot into ash and allows another build up of soot. There are pressure sensors that tell the computer when soot loading is high. Most of the time the truck handles this on it's own with normal driving.
If you do a lot of idle time or slow driving it may not get a chance to burn the soot off and at a certain level you will get a warning. At this first warning drive at highway speeds (Over 40 mph really) for 20 min and most of the time no problem. Ignore the warning and you will get a check engine light and reduced power. Then you will have to go to the dealer to have a "Service Regeneration" done which entails a scan tool activating a 45 min high idle and high exhaust temperature to clean out the filter. Still you will not be left on the side of the road for these issues.
Your 2013 also has Urea injection, a fluid that is injected into the exhaust for NOX emissions. It's in a separate tank that has to be refilled, the dash will tell you when you are getting low.

Yes some truckers are very good at keeping their rig healthy others not so much. I have to laugh sometimes at the cheapskates that will get their oil changed at a cheap place with crappy oil and filters, then have problems that will cost them thousands. :lol
A certain cheap plastic WIX fuel filter has cost many 1k to 3k in injector replacements.
Cheap shops don't even grease the Chassis causing failed steering parts, u-joints and kingpin seizures if you let it go long enough.

Lol that's the first time I've heard of exhaust fluid and it wasn't a joke.. How long before we actually have blinker fluid? lol

Urea is synthetic Cow Piss, smells like ammonia. :eek:
The joke is these new diesel emissions cost you 10% less MPG. (plus the cost of the cow piss)

Just to give you an idea of just how big this engine is in my OP, all the holes around the top are where the valve seats go. The valves themselves are the diameter of the holes.
-
Oh, so that is six valves, not six cylinders in the block. :O
:aok
-
yes six valves per cylinder. 3 intake, 3 discharge. You cant see the actual size of the cylinder in the pic I posted. If I remember I will take a picture of the piston that goes with this compressor.
