I've got some puffs of smoke from the engine bay if I rev it up a little at idle. Not pouring out but a noticeable amount, seems to be oil. Coming from my exhaust manifold/turbo area, no oil visibly leaking and no spots on the ground. I've tightened up all exhaust parts and know it's not an exhaust leak. Where could I be burning oil that leaves some puffs of smoke? I just replaced my oil drain and valve cover gasket, so those aren't the issue. Only thing else I noticed is the rubber coating on my oil feed is melted off exposing the stainless steel line underneath, but I don't think that's the issue because if it was my oil feed line leaking I would be spilling oil everywhere due to the pressure. What are your thoughts? Anyone have a similar issue?

If yours sure it isn't valve cover related it could be the feed line. I think there is a tsb to replace it. See leaking feed lines at Hyundai a lot.

Chokkan

Pretty sure it isn't valve cover. Also not on stock turbo so it's an aftermarket line. Hoping it's something minor

best way would be to clean it all up then add dye to the oil and use yello glasses with a uv lamp.

Have you recently spilled oil anywhere? Touched any of the hot parts with dirty hands?

Chokkan

Just wiped everything down with a wet cloth recently, so any dirt from my hands has hopefully been cleaned off. Could possibley have spilled some oil down onto the transmission or transfer case, but the manifold and turbo are clean. I just can't figure out why there is only smoke if I rev it, but at idle there's not.

You can't see anything when you stand over the engine and rev it? So it's only under load?

Chokkan

No I meant I can't see an signs of leaking oil. I only see the smoke when reving it at idle, puff comes up as the revs fall. Don't notice it while driving but that may be because it's being blown away too fast for me to see it.

When you are looking at the engine, and you rev it, why aren't you able to track the smoke?

godlikelol

can you take a picture of that area not when its smoking but just as it sits there i wanna see your setup,
it is crucial to know because of the peices that are back there you might blow up your car. i had the same issue and found out my problem and i fixed it.
where the exhaust menifold is at where the turbo lies take that pic and post it so we can see

Are they any related smells?

I wana see what "puffs of smoke" on a evo look like

Chokkan

I can't get pictures and videos up later, but I did find the leak. Took the understray off again and the oil has now begun to noticeably leak. Can quite tell where it's coming from as it dripped and has been flung around everywhere. I'm going to clean it up and see if I can trace the source.

godlikelol

put a rag on your muffler and cover it up so that the smoke goes back and then the leak will be more noticable and you can get to your answer alot easier

Sounds like it's an oil leak, not an exhaust leak.
