Smokin' 850 turbo wagon..HELP!!

Okay. Just bought an 850 Turbo wagon, 1994 with 238K miles; I paid $1400. I have owned many high mileage cars, so that did not scare me off.<p>However, during the test drive, the car did not smoke, act funny at all, and drove well for the mileage. The struts where a bit loose, and the steering, but it accelerated well, and had a *slight* shake at idle. OIL was CLEAN, NOT FOAMED, and NOT milky.....no smoke while I let it idle for hte 10 mins I walked around the car before I drove it.<p>When I returned with my wife later this afternoon to pick the car up, she noticed smoke under acceleration, especially when starting from a stop.<p>I looked back and saw whitish-blue smolke. It drive normal, seemed to still pull hard, and did not overheat for the hour long drive home, in stop and go driving.... I noticed it a lot under acceleration expecially after a long stop (got pulled over for no plate on the way home... not ticket, cop just validated the title etc.)... <p>When I got home, I started the car, and opened the hood. Noticed the smoke when I gave it throttle in park form the back of the engine, where the turbo is. whitish blue. small "choo choo train" puffs from the dipstick, some small amount of smoke from the oil filler when running, but NO "beer can opening" sounds.<p>Perplexed. Thought maybe turbo leak? Cooling sys leak turbo? PCV leak? which may have caused ring blow by?<p>The fear: Head gasket, piston rings, valves.<p>Any ideas? Help is greatly appreciated. Want to know if I should try to repair the motor, or if there is a later engine/trans swap I can do for less?<p>Thanks in advance for any help you can offer!<p>Cheers,<p>Scott<p><br><BR><BR>

Here is a check to see if the PCV is functioning properly:<p>Take off your oil cap while the car is running (dont worry, not too much splatter if any will happen), and stretch a rubber glove over it, if the glove gets sucked in, your PCV system is functioning. If it inflates, somethings clogged.

Glove blew up like a balloon, oil dipstick tube puffing like a choo choo train. and the lifters actually make more noise with the filler cap on tight. sounds like the PCV. Gonna order those parts and see what happens when I replace.<p>Thanks!<p>PS - could that cause a lot of exhaust smoke?

At that many miles if the PCV has never been touched I would definitely replace the PCV system.

Re: Smokin' 850 turbo wagon..HELP!! (850arrrsaylikepirate)

Ordered the parts for the PCV system from IPD. <p>I also attempted to get a compressions test done, but the starter would not crank the engine over enough after I finished cylinder one to do the other cylinders. I got 152psi for cylinder 1 (furthest to pass side)..the starter would just spin... I disconnected the fuel pump fuse, and the coil to do this. I even tried hooking the minivan battery up to the Volvo to be sure voltage was good. starter is probably too old and weak.<p>Changed the plugs at the same time.. the plugs where all dry, whitish tan, one electrode was a bit cracked. Car still smokes, but I figured the "volvo" plugs meant they have never been changed.<br><BR><BR>

The puffs from the dipstick tube was the tell tail sign of needing PCV work. The glove trick is interesting but tells you the same thing.<p>Even if the PCV had been done before, it would need it again at this point. Definately go for all new parts. Make sure you clean the PTC! A Seafoam treatment would also be useful to clean up some of the buildup after the PCV is changed.

Re: (850arrrsaylikepirate)

Well getting the compression checked at the local shop. If that comes back regular.. PVC it is. If it comes back low, THICK OIL and drive 'er till she pukes <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (scaswede)

Compression test done. Car has 175 psi in all cylinders. Looks like PCV for sure, possibly valve guides or Turbo... but I am glad the base engine is in good shape. Replacing the PCV system this week. thanks for all the help! I will be sure to update everyone (that cares)<p>

Re: (scaswede)

I doubt your turbo is toast. <p>After the PCV replacement I would still do a SeaFoam treatment.

Re: (850arrrsaylikepirate)

OK. So, replaced the PCV system. Took Sat 4 hours and Sun 4 hours of labor to complete. Still smokes a little bit, but not nearly as bad....<p>Got evertything cleaned up, and replaced all the intercooler and throttlebody hoses.<p>Runs MUCH better at idle, and has a LOT more boost now. But it does *sometimes* smoke when warmer a *little bit*.<p>My car only had ONE hose going from the oil separator up to the intake tube, not the TWO that the IPD diagram shows. There is NO hose connection at the left side of the intake manifold like the forum link with the white 850 T5R had shown. So, I left the hose in the foam bundle, and detached at both ends. <p>Car definitely runs MUCH better. I am goint to remove the intake hose, and really go to town on the PCT this weekend.<p>Thanks everyone for the help... I will keep you posted on what happens once the PCT is thoroughly cleaned out (it was Sunday eve when I buttoned everything back up, and the PCT is easy enough so I thought it could wait.(<p>Cheers<p>
