850_GLT_owner Posted April 23, 2011 Author Report Share Posted April 23, 2011 This might sound stupid but heck the oil filter. I thought i had a major problem but when i went to take a closer look it was a loose oil filter. It dripped a lot when running and dripped for a little while when turned off then stopped sounds like your problem. I can actually see the oil dripping from the oil Tstat housing,only when running. I was thinking it might be more things than just that but there is enough oil leaking from the thermostat housing that would account for all the oil i've been losing, like a drip a second or two.

It seems like its coming from that area but i'm pretty sure its the oring going into the Tstat Link to comment Share on other sites More sharing options...

Be 100 % sure it's not something else. Replacing the two o-rings for the cooler lines is a PITA job you just want to be sure. Link to comment Share on other sites More sharing options...
g96nt Posted September 17, 2011 Report Share Posted September 17, 2011 Did you ever solve this? mine is leaking profusely from the passenger lower side, too. the timing belt is dry, and so are the pullies. initially, I thought it was a bad front seal, but I think the belt would be wet with the amount of oil I'm losing. we're talking about a quart/week right now, and it's covered the entire passenger side of the under-car. I saw someone elsewhere mention that it may be oil thermostat gaskets? for reference, I have a '00 motor in my 850, so it's got the oil cooler in the oil pan. ( I think that eliminates the oil cooler lines?) Thanks, guys! Link to comment Share on other sites More sharing options...
rmorse Posted September 17, 2011 Report Share Posted September 17, 2011 If your oil cooler lines are wet then they are leaking. The only other area I've seen that can leak a ton is the turbo drain tube seal and rear main seal. Damn it. Someone +1 him. I'm on my phone and accidentally -1 him while scrolling.

g96nt Posted October 8, 2011 Report Share Posted October 8, 2011 I fixed mine. Ended up being a cracked turbo oil feel line. It was dripping from the banjo bolt @ the block, and making a hell of a mess. I bought a turbonetics 3' stainless line from summit for $25 the appropriate banjo fittings for $25, and swapped it out. I had to cut the old line in half to remove it without removing the turbo coolant lines, which made me happy I chose the stainless line. Dry as a bone, now, and won't need to be replaced if/when I upgrade the turbo. Link to comment Share on other sites More sharing options...

BlackBrick Posted January 31, 2012 Report Share Posted January 31, 2012 the only time mine lost oil that bad was a cam seal. because it's so high up, that oil can go anywhere it wants. Link to comment Share on other sites More sharing options...
850_GLT_owner Posted February 1, 2012 Author Report Share Posted February 1, 2012 Didn't notice this thread was still alive. I've been trying to close out the threads i've started with what I did to solve the problem but I forgot about this one. It ended up being bad orings on the oil thermostat housing, where the lines go into the housing(picture 2 on my imgur link). Needed 3 seals(2 orings for the lines, one rectangular-ish one for where the Tstat housing meets the oil pan) Make sure the orings and the area where the orings are going is clean of any debris. The hardest part was getting the rectangular seal to stay in place. If i remember right the oring was rectangular, but the groove where it sat had some sort of notches that made it hard for the seal to stay in. I thought I got it so many times, just to feel around the area and feel the seal had slipped out while i tightened it. To make matters worse, it kept falling on the ground and picking up debris, so I had to keep cleaning it thoroughly. I ended up using a little liquid silicone gasket in the groove to get it to stick in place while I was tightening it down, and after a few tries with that it ended up going in...no more leak. I haven't stuck my head under there since I did it, but I don't see any oil on the ground. It got to the point where I was losing over a quart a day, a decent oil puddle would form any time I was idling in place. This job is cheap if you do it on your own, even using genuine volvo seals(less than $5 if i remember correctly), but it can get frustrating if you don't take your time to do it right.

BlackBrick Posted February 2, 2012 Report Share Posted February 2, 2012 thanks for the followup! I'm about to replace my oil cooler lines, and i will definitely use a little silicone gasket to hold it in place. Link to comment Share on other sites More sharing options...
