When you get an oil hit, engine immediatly sounds clunky... seems like it would take a little while for oil to fully run out before the engine got real bad.
Maybe not a bug, but should consider using sound only after a certain amount of time unless that's really what would happen.
-
Added bomb bay, wheel brake, engine damage, parachute opening, and plane fire sounds.
Amazing what happens when you read.......

I know that... saying in RL, I'm guessing oil takes a bit to run out... not immediate engine clunking. Maybe slowly phase it in as the normal engine sound phases out.

You mean you think the hole should be a hole and not have bits of the shell and broken engine grinding inside? :D

Well, if it had bits of engine, could it keep running for so long? The oil hit, with the engine running for a while longer, seems to simulate a hole with oil leaking out and burning/smoking due to running all over the hot engine... And windshield.
There are engine hits that cause the engine to shut down immediately, as it should.

yes it could continue running. i had a transit van conrod come through the engine casing. the engine ran horribly and noisily till it seized. but it still ran and provided motive power. The ability of the engine to continue to function is obviously dependant on the damage done and what is rattling around inside. A 50 cal round is relatively soft in comparison to most engine internals. It would not be condusive to smooth running or longevity but multi cylinder engines will run with one or more cylinders damaged until the oil pours out or the there is catastrophic damage caused. a round smashing into the crankshaft and causing it to fail would almost certainly cause an almost immediate engine failure.

You don't read any books, do you? May I suggest military aviation history.
The US Navy in particular had a thing for its radial engines - numerous pilots would live to tell tales of missing a signifigant chunk or two from damage and making it back over the open ocean to their carrier many miles away.

Well we blew a jug on an r2800 last year and it sounded no different than when it runs normally... We also were able to make it back to base which was over 150nm away but only lost about 15 gallons of oil. (we carrying between 30 and 50 gallons per engine).

That's my point... the clunky sound kicks in too fast. nuff said. :salute
-
I think Robert Johnson in his book wrote that when he landed in England his engine had two cylinder heads blown off of his radial.... I think might make a little noise.

You seem to be assuming a simple oil leak instead of mangled engine parts getting pounded as long as the engine is running.

Midway,
I hope this is helpful and distracts your attention from how quickly the sound arises. You can easily turn the sound down, and you will hear a smooth running engine. Here is where it becomes fun though :rock You can create any sound that you would like to replace it with. I have done this with the stall horn which in most any dogfight is buzzing away. Instead I copied a decent engine shut down sound and adjusted the volume, so now the engine sputters momentarily to alert me of the impending stall.
In order for sound to appear later than the actual damage, a new criteria must enter the coad. To make a case for your "progressive" damage sound, possibly the oil temperature guage would initialize the sound sort of like the external wind sound kicks in at certain speeds. While your at it, why not add a buffeting noise when a airplane compresses and starts to shake.
Now, that I have distracted you enough with other possibilities, please note that the sound is not a bug, but your suggestion could very properly become a decent wishlist item.
:aok

Should have been posted in "wishlist"... I like the new sounds....

Thanks, Chilli... This does help. The issue is whether the damage is jut an oil hit/leak vs immediate engine damage. Maybe this does belong on the wish list assuming it is suppose to just simulate an oil hit, which is what I thought it was.
-
The clunking sound comes on immediately because something has damaged the engine.
Damaged engines can make noise regardless of oil pressure.

what happened with us was that a crack formed in the cylinder head. As the engine warmed up it expanded. The cylinder head then pinched the pushrods causing the pushrods to break and blow through its case. As the cylinder head continued to separate cooling fins broke free and entered the compression chamber. The top of the cylinder was held on by one side of the jug.
Other than the oil trailing off the nacelle, the only indication that something was wrong was the fact that they couldn't lean the engine. Every time they tried it started to backfire. There was no sound change.
This is us landing on that flight... And here are some pics after we parked

Many people aren't gifted with being able to hear an engine that is in distress yet still seemingly ok.
I remember a C130 we loaded at Dulles (signature) and I could hear that the bearings were done in one of the engines and mentioned it to our FBO A&P and we discussed it to the point of argument before I convinced him.
We approached the pilots who blew us off because they were looking at the ferrari and multiple high dollar watercraft they were transporting.
The C130 suffered an engine failure and had to land in new york a short time later.

I've lost several R2800s in C-118s and a C-131. Usually, a cylinder suffers a failure (heads blow off, or partially blow off), con rods break or any number of various mechanical failures. However, the engine will make good power on the remaining 17 cylinders. Your biggest risk is fire. If feasible, feather the prop and shut it down.
Depending upon the problem, you may need to change the engine, or more commonly, replace the affected cylinder. That will be determined after the post-flight inspection.

Glad you made it.
In Aces High as far as I know the engine is only damaged by projectiles, overspeeding prop, or collisions. When the engine is damaged by projectiles the oil leak is from the engine damage and is not the cause of the engine damage though it may be the cause of the engine eventually stopping.
