I have an oil leak in my car. I don't know if it's coming from the valve cover (?) or somewhere else. I know one mechanic wanted to put something in the oil to discolor it...but can I do this myself? I know replacing the cover would be pretty easy, but I'm not sure that it needs to be replaced...just one of the many places it could be coming from. It's on the top of the engine, I can see it and it's corroding a belt...any suggestions would be amazing! thanks :)

It is very common for the valve cover and intake manifold gaskets to leak oil and coolant on the 3.4 and 3.5 engines. So common in fact that there is an updated intake gasket set and bolts to address this problem.
We use a video borescope to see exactly where they are leaking before repairing them.
It runs about $900 to properly repair including parts, labor, oil change, coolant flush, cleaning, and tax.
