2005 z with 68k miles one it. Smoke starts once car is warmed up. Looks like oil on the exhaust manifold might be burning but can’t tell because the smoke is kind of dense. Oil all over under shroud area from front of oil pan back to the jacking point. Can’t tell where all the oil is coming from. Any help greatly appreciated

 

Welcome- have you tried jacking up the car, supporting it on jackstands, and inspecting the PS? You need to remove the splash guard to look at that area, but it's the only way to know for sure. Any other advice is just guessing, so let us know what you find.

 

Thanks for replying. Jacked it up removed the shroud and cleaned up the oil that was underneath. I just replaced the valve covers so maybe all the oil came from there. I see a lot of oil mainly on the exhaust manifold. But I’ll get a uv leak test and see if I can pinpoint it.

 

Almost a sure bet it's from leaky valve gaskets. Be sure to use a lot of brake clean on those exhaust headers or it'll continue smoking.
