How to fix an 850s leaking oil return line

Post by **matthew1** » 17 Jan 2005, 21:39

Sorry no pics. I just got an email request for this and I've done it so here it is from memory.

Go to the dealer and ask for the oil return line gasket and o-ring. Should be around the equivalent of $5-10 US. Then drive the car up on ramps or jack it up to get under it. BE CAREFUL, a family friend was killed by his car falling on him while he worked on it.

Look for a metal line about 2-4cm diameter and perhaps 10-14cm long right behind the engine. It's tucked away and you'll need to do this in daylight to see it. You'll need a metric ratchet set or hex driver (can't remember sorry) to get it off. It twists out and back in really awkwardly -- just keep at it and you'll get it. Replace both the gasket and o-ring and reassemble.

As Matthew states, it is a fairly easy fix. I bought the seal and gasket on line for less than 2 dollars.
Once your under the car you will clearly see the pipe coming from the turbo going into the oil pan.
It was a little tricky getting the pipe out due to other things in the way. but just keep at it and you will get it.
It took me about 5-10 minutes once the car was in the air.
One oil leak fixed and a couple others to do. (Rear main seal).

Had the car towed to an ex-volvo man today. He said the cam seal failed sending oil down the front of the engine dripping onto the cv boot. He said the timing belt was oil soaked serpintine belt soaked and the opposite side cam seal was not seated correctly. Even though the car showed a timing belt change at 69000 on the under hood sticker and the car has 109000 he said that the cam seals were another color than OEM volvo and thought that was to blame. Recomendation is change both seals both belts button it up and pay $475 - $500. OUCH! His other observation was that motor mounts needed to be changed. Two out of three were bad enough to be replaced. $375! OUCH AGAIN! I'm not confident enough to do the timing belt myself ( I need someone to blame if it fails) but how about the mounts. Can they be done in the drive way with normal tools and jacks?

Once Again Thanks For The advice & Help,
