I'm curious if anyone has any leads that may cause this much spot build up on the passenger side of the engine? This is just to the right of the belts. Exhaust leak at the manifold? Apologize for the poor pictures.

 

Looks like an oil leak to me.

 

Looks like an oil leak. Trace it to very top to find a starting point. Could be a valve cover gasket.

 

Timing cover gasket leak. It probably doesn't even show on the dip stick, its more of a seepage. 12.5 to 13.5 hour job, about $2,800 parts and labor.

 

I really appreciate the feedback. Hoping it won't be that major of a repair! Thank you.

 

For valve cover gaskets!!!!!!! I miss the old days..

 

Check PCV valve, make sure it is opening/allowing air flow only one way from valve cover into intake manifold. I assume your engine is turbo charged. Leaking PCV valve that allows positive pressure into valve cover will cause oil to get pushed out from seals like valve cover gasket.

 

Thanks again for the help. I was told by the dealer service department that the front engine cover is leaking oil. $2,800 repair as perfectly estimated in this thread. Not only expensive, but about 6 weeks before their engine tech could look at it.

 

Ugh, what engine?
