Burning oil 850

posted by  someone claiming to be GB on  Wed Mar 5 08:52 CST 2003 [RELATED]


I've just had my 1995 2 litre 20v 850 in the shop for a couple of issues. They noted while it was there that it was quite smokey and ran a couple of diagnostics:

The lamda sensor was gone
The crankshaft sensor was gone
There was blue smoke on startup and after a few minutes idling.

I have been told that I should probably look at getting another car as mine is burning oil and would probably need an engine rebuild!

These guys are not volvo specialists and I want to know if there is any simple solution to my problems that they are unaware of?

    Are you burning a lot of oil between oil changes? I think
    Volvo says 1 quart every 1000 miles is within normal (so they
    can burn a lot of oil).

    How many miles on the engine?

      There is 122K on the clock.

      I have used about 4 quarts in the last 3000 miles.

    don't know about the sensors, but blue smoke is an indication of valve stem seal replacement.

      Take it to another mechanic. Blue smoke could be a head gasket leak or worse. May be minor repair, may be major. Depends on how much you want to keep your Volvo. Perhaps try some over-the-counter smoke treatment that you pour in. Wouldn't hurt. I have a friend that poured some in his '89 Chrysler LeBaron. Stopped smoking, seriously : )
