Want this question answered?
Is te oil leaking from the turbo into the exhaust, or is it that the oil is leaking from the exhayst into the supercharger? I have a 2004 Jetta that is leaking oil from the exhaust port into the supercharger. I think that the culprit is either a bad valve guide, or exhaust valve oil seal. Write me back and let me know what you find.
Valve cover gasket
Need to replace the valve cover gasket.
Yes it sure can and will if the valve covers are leaking oil and the header gaskets are worn out/ leaking.
Are you referring to a loud exhaust sound? If so, it could be (Going from the engine back to the tailpipe) a cracked or leaking exhaust manifold - a leaking exhaust pipe - a leaking catalytic converter - a leaking muffler. That covers the exhaust system. If you are talking about a noisy clattering sound in the engine, you could possibly need a valve adjustment.
The oil leak is coming from the valve cover gasket and leaking onto the exhaust manifold, the rubber valve cover gaskets get hard from the engine heat and start to leak, you will have to replace the rubber valve cover gaskets to stop the oil leak
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
Valve cover gasket is probably leaking oil onto the exhaust manifold or the oil filter may be leaking oil onto the exhaust pipe.
Worn piston rings, bad valve seals,
I suppose it could but more than likely you have a stuck egr valve or some other leak.
It is possible that a part of the EGR valve has fallen out. This will cause a very loud exhaust noise.
Leaking valve cover gaskets would leak onto the exhaust pipes under the hood of the car.
