Hello all. New to this group. Wondering if anyone could help me to make a decision? Looked at this 2001 S40, with 1.9t today. Less than 85k miles on it. Automatic. Looked fine, ran fine. (Did have a misfire cyl 3 and 2 cel on, which I assumed to be a coilpack?) Anyway, took it out and it ran and shifted fine. Ran it about 8 miles up the road at normal highway speed. When I returned, I noticed an oil smell. Opened the hood to find oil under the hood, and over the coilpack cover, and rails. Figured it came from the dipstick. My question is, is this common? Would I be looking at a clogged pcv system, or something more major? I have read some threads that talked about new o rings, but thought I would go to those more experienced. Any ideas or thoughts? Anyone? The car is reasonably priced, and frankly I want it, however, dont (or cant) afford a engine rebuild at this time.
Thanks in advance.

 

Check the oil cap. If the o-ring is worn or not fitting right, oil could leak out from under the cap and spray on the top of the engine.

 

Your thoughts about the crankcase vent system is correct. At this age, the system is probably clogged and has never been serviced. O rings are aged and are also a common problem. Could be a good deal.
