I just got the turbo on my '97 850 GLT. When I put it back in I hooked up all the oil and coolant lines right and they have no leaks, but about 2-3 minutes after the car has been running, some oily yet sweet smelling smoke starts to plume up from where the turbo sits. I can't tell what's smoking because the oil and cooling lines aren't leaking. Any ideas or help on this would be GREATLY appreciated. Thanks guys.

 

Are you sure they are hooked up correctly to the right places?

 

99.9% sure, the hoses aren't really long enough to reach a place where they aren't supposed to be.

 

If it is 'sweet smelling' it is most likely antifreeze. Check your resovoir for the level.

If you spilled when taking it apart it will smoke like that till it all burns off.

Take it for a ride as long as you know it isn't leaking anything.

 

yeah I think I'm gonna try taking it for a drive tomorrow morning, hopefully it'll sort itself out. If it doesn't it looks like I'll have a lot of guesswork to do

 

Let us know what happens.

 

yea the smoke definitely didn't go away...actually the car stalled....it started running very rough then just died, about 20 mins later I could start it back up and limp it home. this is the whole reason why I got the turbo rebuilt (the whole stalling issue)... any ideas about what it could be. for reference it's a '97 850 GLT with about 217,000 miles on it (I know it's a lot, but hey, volvos are supposed to last until the end of time right?)

 

Any Codes?

 

no codes being thrown...it runs great for about 10-15 mins, then starts to run pretty rough, then it just dies. but about 20 mins later it'll start up and run fine for a little while, then the same thing happens

 

Tune up done lately?
Is it missfiring?

 

the car was running great before this happened, there's no misfiring. the last time I changed the oil their appeard to be a milky substance in the oil. I guessed that it was coolant that had leaked into the oil. I asked around and most people said it was either the headgasket or the turbo where the coolant was mixing with the oil. I got the turbo rebuilt because 207,000 miles is quite a bit for a turbo, but it's doing the same thing now. I'm at a standstill now.

 

What does the oil look like now?
Does it run hot?

I would do a compression test.

 

If I lived in the US I'd take an oil sample and get it tested in a lab.

 

the oil's looking pretty clean, and I'm gonna get a compression test done soon.. and it doesn't run hot at all. it runs right in the middle where it should be.

 

Let us know how the compression test goes.

 

Well, if he got antifreeze in the electrical connectors that could be a problem............... After the engine runs and heats up, the antifreeze could be "steaming" and get into the connectors............ It has happened to me before.
R.

 

which electrical connectors are you talking about? and I'm doing the compression test right now so the numbers should be up in a few hours.

 

oh and does anybody know what compression numbers I should be looking for? it's a 1997 850 GLT with around 207,000 miles on it. thanks for all your help guys

 

There really isn't much in writting to the specific numbers.
They all need to be within 20% of each other.
They are ususally at about 150-160 PSI.
