I've searched and can not find the answers for several questions. When an aircraft has damage and the engine oil leak starts, how long will the engine continue to run? Does the oil lead out at different rates? Is the Oil leak damage model different for each aircraft or is there just one oil leak damage program and it's the same for every aircraft engine that suffers that type of damage? I know if I get engine damage in my P38 that the engine will continue to run for another 3 or 4 minutes. But I just chased after an F4U that from the time I started chasing it, ran for 7 minutes.

it depends on the airplane. at full throttle the engine will overheat and die faster than if you go let's say 3/4 throttle. I think the ponyd engine will die in less than a minute at full speed. spitfire will go forever. same for the heavy buffs. in the c205 my engine will last at least 20 seconds with proper throttle management. not sure what I do wrong with that lol.

Don't know about the damage model.
But I do know that in real life radial engines often have larger oil tanks then inline or V engines, since they tend to leak/burn so much more. I've been told that on P&W 2800 they have to be burning more then a gallon per hour before they even think about worrying. So a Corsair running much longer with an oil leak then a Lightning sound right to me.

Realistically it would depends on the type of engine, the size of the hole, and your power setting. In AH I don't think the size of the hole matters so it would be the same time for each type of aircraft.

Think you're right. In a hog you can always go at least a sector with an oil leak. Never varies.

a pony can last a while as well, I chased down and killed the HOin jerk that gave me the oil leak and was half way home before the engine quit. :devil

No clue on the damage model... 190's seem to go forever though, and will coast out for a long time also. After your engine dies, hit the minus key on your numeric keypad, this will increase coasting distance.
As for how long your oil lasts... keep an eye on the oil guage of your affected engine is best I can say.

Luftwaffe planes seem to run forever without oil.

Oil Leaks modeled in Aces High varies from my experience
example:
1st flight: I get an oil leak - I watch my oil pressure gauge, it is moving ever so slowly leaking out
2nd flight: I get an oil leak, the gauge is dropping faster than the 1st flight damage I took, and oil is leaking out quicker
3rd flight: I take a hit to my oil reservoir or whatever and I am losing oil just as fast as a person could possibly pour the oil in to the reservoir
edit: above example is given for the same plane type ( F4U-1 )
oil leaks leak at different paces.... slowly to very quick
fuel leaks leak at different paces.... slowly to very quick
coolant leaks at different paces.... slowly to very quick
you can tell by how fast each type of leak is by watching the gauge connected to the type of leak you might have
hope this helps

radiator hit != oil hit

I recommend actually stopping the prop instead of feathering it, significantly increases your glide distance.
See this thread for numbers: http://bbs.hitechcreations.com/smf/index.php/topic,308176.0.html (http://bbs.hitechcreations.com/smf/index.php/topic,308176.0.html)

To clarify what MachFly means.
On planes who's prop will not feather, you can increase glide distance by zooming straight up until the prop stops. And then continuing a slow glide. VS just setting min RPM.
Planes who can feather , the prop automatically stops do to feathering.

I had a Dodge Omni that lost oil pressure. It lasted about 2 minutes and got so hot that it fused the pistons to the cylinder walls.
I had a 64 Plymouth Valiant (slant 6) that ran outta oil. I drove it another 50 miles home, the engine/exhaust got so hot that it caught the leaking oil/crud on fire when I pulled in the driveway. I hit it with the fire extinguisher, put another oil pump in it the next morning and drove it for another 30k miles and the rod knock that was previously there mysteriously disappeared :rock
It is all relative to engine type, design, etc :aok

Why is that neccessary or part of this conversation?
-
Oil hits have always varied for me. And shutting off the engine never really seems to help with cooling. But that's all anecdotal.

Why do you feel the need to ask?

Lol VonMessa, I had a buddy many years ago who had a 'cuda with a slant six. He wanted to get rid of it so he decided to blow the engine. We drained the oil and ran it on the interstate to the next town (about 13 miles) turned back from the offramp and came back. It was still running so he put oil back in it and while I don't know how many miles he put on it afterwards, I do know he drove it for quite awhile. Those things would last forever.

Shutting it off definitely helps cooling. If you take a radiator hit, you can most certainly nurse your plane home by keeping a close eye on the temp guage and shutting off when it gets hot. I've flown as far as two sectors to get home this way.
Unlike an oil leak, the radiator leak can be managed indefinitely.

In 190's you have to worry more about a radiator hit. Seems 20 times more likely to get hit than oil. You can probally go a sector with an Oil leak. As long as your gear are ok I've set the 190 down with a radiator hit, engine off, let it cool and have leapfrogged back to a successful landing. Watch for Trees! lol

I think the engine will not over heat until you are completely out of oil. I also think it depends on the amount of oil the plane has and not on what kind of damage you took or anything else. Could be wrong though.

I usually fly it till I fry it. Costs nothing to get a new plane :P

Based on what I've seen, I'm fairly certain there are at least 2 types of leaks for anything (slow and fast). There might be more, I've never tried to narrow it down any more than sometimes a leak runs you out fast, sometimes slower.
I can only assume you guys that are talking about the 109s running for a long time with an oil leak aren't comparing it to the radial engine planes. A P47 will run forever oiled. 109s to me seem to conk out after a minute or two.

i ran a toyota forklift petrol engine flat out with no oil and it ran for just over 25 mins before she screeched and seized
