Hi everyone, I am hoping someone can help me understand what is going on in my engine. I have read most of the threads I could find.
I have 07' GXP, I started noticing oil loss first off. Then I noticed occasional white and black exhaust. Sometimes in succession. Now I am getting a thin film of oil on the inside of the hood directly above the oil fill cap. It's not much, and it appears to be coming from the oil cap. I have also noticed a decent amount of oil in the charge tubes (enough to run when tipped). Cleaned twice and keeps returning.
I am assuming I have some sort of back pressure that is forcing oil out the oil fill cap.
After reading forum articles, I noticed the check valve that runs from mid engine to the MAF is clogged and I intend to clean that first. I have also ordered a PCV valve and intend on taking the intake manifold apart to inspect/clean or replace the PCV valve.
Maybe its the seal on the turbo?
My next step if all of the previous is unsuccessful, is to use a leakdown tester to see at what psi the piston rings allow air to flow past.
I hope it is not the latter as the fix will be intense work :brentil:
Any other thoughts? Suggestions?
Nationals is right around the corner and I won't take the car on a long road trip with it acting up this way.
