I have a small oil leak from the rear of my Yeti 1.2 petrol (Chain cam) engine. It seems to be from a plastic cover just above the back of the oil sump. Any suggestions of what that component might be and how big a job would it be to fix?

Many thanks.

Sounds like the oil separator. Item 23 here: Car Parts Catalog - LLLParts

It's not an easy repair, to be honest. Offside driveshaft really needs to come out for access, which is from below. Awkward to see and work on. Nothing technically tricky, just awkward, and has a sealant seal rather than a gasket.

One thing that might be worth checking first is for other oil leaks that may be dripping down from above that area, giving the false impression that the separator is leaking. The throttle body sometimes receives oil via the turbo, some of which seems to get down the outside of the intake manifold.

Have a look where the boost pipe attaches to the throttle body, see if there are any oily messes around there.

Very many thanks Pete. I will follow up the lines of enquiry you suggest! It will be a visit to the local mechanic I expect (due to access) but it will give me a few points to discuss. Cheers, Ian

Whereabouts is local?
