In particular, look at the engine block behind the oil filter housing and under the intake manifold. This will definitely require a flashlight. My problem is at least partially due to a failing CCV system that must have been cracked and was leaking oil onto the block. I may also have an oil filter housing gasket leak but no way to tell yet. The CCV on my car failed big time ~10 days ago and I was suddenly burning tons of oil. I replaced the CCV and all hoses this week and found the engine block behind the oil filter housing and underneath the intake manifold was covered in oil. I also found the power steering hoses are leaking and contributing to what is dripping from my car. The best way to inspect these is to drop the plastic cover underneath the engine. My car has about 130K miles on it.
Im at 130K now also. Dealer replaced the Oil filter gasket maybe 3-4 years ago. My CCV is new. My Valve cover gasket is still orginal and I will focus on that. Will definitley go over the engine with a flashlight more thorough. Thanks
