What happens when you take the oil filler cap off when the engine is running at idle? (DETT engine).

 

[GTR RGT]

depends, hot or cold?

Not much, some steam is coming up and it idles not so smoothly. But when you drive without the cap it´s getting messy under the hood and you run short of oil...not good

Cold

Maybe a few oil splashes, maybe nothing.
Depends a bit on if your engine 'breathes' much.

The idle drops but no oil comes out when idling.

just dont remove the cam cover

I found that my engine drops in revs, no oil splutter or anything. Is this a sign that the engine is in good condition?

 

[gtr mart]

when the engine is running, if air comes out of the oil filler cap then I think this suggest ring/piston/bore wear problems. A good gtr should not "breath heavily" from the oil filler.

Why would anyone want to run it like this
