smoke from audi s2 exhaust manifolds

[Markmark]

hello everyone any help? I don't understand where it leaks oil from to make a lot of smoke and a burning smell from the side of the exhaust manifolds, the only thing I noticed a small drop from the turbine vent

Hello , could you resend the picture ? Have you draw something with black line ? One drop can smoke pretty good.

hi I have a video but I can't upload it when the machine heats up smoke comes from the collectors / turbine head gasket and various manifold valve cover gaskets etc. are all new as soon as they are assembled

try to put it on youtube and post the link .. if you have assembeld everything and yiu hade oily fingers ,, the oil smoke will disappear

Have you driven it yet (after rebuild)? Any oil and grease on new parts takes a while to burn off.

It could be a leak from the oil feed or drain from the turbo or possibly a leak from the cam cover. Failing that, it's just burn off if you have rebuilt that side of the engine recently.

[Markmark]

it's not clear, it seems to derive from the turbo exhaust when the car is in motion

[SteveH]

Has the turbo been rebuilt? If it's the original the shaft seals may be on their way out

[Markmark]

rebuilt 800 km ago with internal shaving and bearing

[Markmark]

Is it possible that a gasket is missing from the turbine oil drain pipe? it could leak from there when you accelerate

[newsh]

Yes, or either the feed or drain flange has been over tightened and is bent .

Someone hasn't put nyloc nuts on the exhaust manifold and the nylons smoking as its melting. Just a thought !.
