Engine oil with a funky smell

Post by sanlo »

Hey there,

Like most people, I had some free time at home and decided to look for issues with my 2001 Xsara 1.6 (TU5JP4).
I found a small oil leak coming from the valve cover. After removing the valve cover, i noticed a weird smell that I couldn't really identify. I guess it could be gasoline or burnt oil, I cant be sure.

The last oil change was 7 months ago (about 4000KM). Looking at the dipstick, the oil isn't black, but it also have the distinct smell.
Last month, I made a 1700KM trip and i had no issues and no noticeable loss of power.

Anyone can guess what could be causing this issue?

After taking a long look at the enginr bay, I noticed that the EVAP valve (green line) connects directly to the intake manifold and the crankcase (red line).

Could it be causing this issue? Using Lexia, I didn't find any error codes related to this issue.
