I saw the OMFG thread about small oil leaks, that helped...but....The car has had a steady and medium sized oil leak since i bought the car. I thought I fixed the problem a few weeks ago, but I guess it wasn't the problem.

There is a steady drip which comes from the passger side, underneath what looks like either the oil/feed return system, or the turbo or manifold. It drips about 1 drop of oil evry 3 seconds or so while running. As you can see, the oil drip off to the right side, then collects by that frame support/joint.(rubber cirular part.). Ive tried power spraying the undercarriage and area that had lots of oil, to see where it was coming from, however no such luck. I dont have very high jack stands. I took off the intake pipe and box to free up some work space, also the turbo does have some shaft play, wondering if that could be related......

The car also idle surges about 300 to 400 rpm, Im not sure if these 2 problems could be related, but also the TPS was replaced not long ago. It was replaced by the previous owner, so I know nothing about it. Ive read to try and spray brake cleaner to find vac leaks, maybe ill try that. Any help and advice would be awesome....Thanks!



this is where most of the oil collects and drips from, the frame and turbo/manifold area.







This is a shot from the engine bay looking down at the oil feed/return system I assume....Theres plenty of oil around this are also.





This is a close up of the same area....Keep in mind I cant see oil actually bubbling or soming from any visable spots here, but there is alot of oil here, so the problem is either here, or nearby.



I was also thinking it could be a cracked turbo exhaust housing. Since I cant really hear the turbo spool, basically at all. The car builds boost however. Could the oil possibly come out the wastegate????



Thanks again for any help!!

I had a steady drip like that and it was the shitty mechanical OMP.

yeah omp's are a bitch when they leak, and they usually do. only thing you can really do is clean around the omp and start her up and watch for a bead forming around there. it is probably where the problem is. when you search for vaccum leaks use starter fluid because it works a lot better than brake cleaner and it won't be as ready to take off your paint..... decently clean underbody tho!

thanks very much guys, when im off work ill check it out. Thanks for the underbody props too. The previous owner did an amazing job of storing this car during shitty days and winters. Thanks Scott! With the starter fluid, can I just use regular kingsford lighter fluid?? I know it sounds absolutly retarded potentially turning my FC into a bomb, but I wanna make sure im supoose to do this the correct way......Ive heard brake cleaner, lighter fluid, and WD-40 but i think the wd40 would make a mess
