Oil leak ... 850 1995

I usually am on the 240 side of the Brickboard.

I have an opportunity to purchase a 95 850 with only 121,000 miles.

I've seen the car once and for the price, $500, I think it is a good buy. It has a leak that the owner seems to thinks is at the oil dipstick, yet the hoses adjacent to the dipstick are dry. I looked underneath the car yesterday (during the rain) and did not see any obvious leaks.

Coincidently I am changing the oil trap on my 240 this week.

So the question is, not having a manual and not having worked on the transverse engines yet, does this engine have a similar set up for crankcase ventilation; an oil trap?

Good source for manual for these vehicles?

I've had others work on my S60, now I might want to jump in.

Any advice is appreciated.

    Oil leak ... 850 1995

    If this car is a turbo, there are oil cooler lines that go from the bottom of the crank to the right side of the radiator. Those lines will age and leak, and are $100+ each to repl.

    The oil separator never leaks. The vacuum lines to get old, brittle, and need replacing after about 150K. Replacing the oil separator is a 5+ hour job, the intake manifold must come off.

    Ask to pull off the timing belt cover, one 10/12mm bolt, and see if the cam seals are leaking. That is a hard job, but doable in the driveway.

    Using a bottle of AutoRx should clean out everything where oil and vapors go. It take 1,000 miles, you must not use synthetic oil during the treatment.

    Check the tranny fluid, the yellow dipstick is under the air intake tube just behind the radiator - driver's side. If the fluid is black and stinks, let someone else take the car to the crusher.

    The 1995 has OBD boxes on the passenger fender. Checks tranny, fuel injection, ignition, ABS, SRS, instrument cluster, etc. A great tool.

    For a basic manual, get a Haynes for the 850. There are no more Green books.

    Yes there is an oil trap on the 850. I don't know how bad the job is on a 240, but its about 3-5 hours on the 850.

    As a 240 owner, you probably know about the rear main seal. Make sure its not blown on this 850. Easiest way to tell is drive the car for a few minutes, then while still running look under it. Usually the oil won't drip out unless the system is pressurized. Fixing the breather system might help re-seat the seal stopping the leak, but if its too far gone, prepare for either a big job or a lot of money missing from your wallet.

      Thanks
      On the rear main for the 240, I've purchased it and the gasket ... waiting to see if the new oil trap solves it. My guess is it won't. I've pulled the tranny on a previous 240 I owned so I know what I am getting into. Still dreaming for a home with a garage as I am a driveway mechanic!

      On this 850 I am thinking of buying for $500; the leak appears to be on the passenger side. The owner has it parked and the leak is all around the left front of the driveway. He showed me all the work his mechanic did, saw the new master cylinder, power steering resevoir, timing belt, brakes ... I'm thinking, maybe wrongly, that it could be the oil trap and voila ... I'm good to go.

      Not sure if it's worth it if it is a rear main (sidemain on a sidewinder, hahaha).

        That side you have the oil separator, the cam seals, and the crank/oil pump seal. Of course the dipstick seal is in the area. Check the oil filter to make sure the leak isn't coming from there (and if it is coming from the pan, you're best to walk away.. unless of course, you get that garage with an engine hoist..) Timing belt cover isn't hard to get off, would tell you a lot. Cam seals aren't awful to replace, crank seal is a little more involved, but not in the ballpark as a RMS.


        You might have success with putting a bottle of Auto-RX in either car. It helps recondition the seal, which might help the 240 stop leaking...

          Besides the oil filter, the aluminum oil drain plug crush ring will leak if reused too much. Either one should leak just a small amount.
