| 3.6 TDV8 weird smelling engine oil - Diesel contamination? | |
Greetings all, been reading a lot here for years now and finally have something I need some help with.
Car is a 2008 3.6 TDV8 with about 240k kms (150k mi). Issue is, the engine oil smells funny. Been that way for at least 20k kms now.
Some 5 months ago I noticed the oil level went up a tiny bit after couple thousand kms even though LH side cam cover was leaking slightly (so should go down not up). Since then I had to put a liter in and it's somewhat staying the same now.
I'm now in the process of replacing both cam covers and I'm surprised how clean the engine looks inside.
I'm thinking there's a bit of Diesel in the oil which would explain the cleanliness and slightly rising oil level and possibly the smell.
Question is, where is it coming from? Could it be a leaking injector? It does have a slight fluctuation in idle speed intermittently, can barely tell by looking at the rev counter but can hear it when listening closely.
Or could it possibly be the shaft seal of the high pressure fuel pump that's leaking a wee bit?
Hoping someone has had simular issues, open to ideas 
Thanks guys
Karim
