Well my sister owns a 1996 Volvo 850 Turbo with about 180k miles on it and she has had somproblems with it in the past it would burn alot of oil and smoke horribly. That was fixed and now her car smokes agian it seems to be coming back from where the turbo is. I really havent dug in to it to see what it is but i think it is coming back from where the turbo is.. well definity on the back side of the motor or maybe on the bottom.. The reason i am soo concered is she is at Spain for a semester at college and when she gets back she is gonna sell it and im looking into buying it.. i drive a 89 240dl right now and boy i love it.. 260k miles and still running.. doesnt even burn any oil. i just fell in love with volvos because the are quick and excellent handling cars. i live near a busy back road very windy and hilly.. through some sections of this road im doing 110 and my 240 sticks to the road no problem.. I have beaten many audi a4's, a6's eagle talon, eagle talon TSI, 1.8T. VR6's, trans ams, camaros, mustangs...lol sorry bit off topic..

Any advise on the situation would be great..

Oh How much would a rebuild be for one of these cars.


Thanks
Sean..

 

You would have to see exactly where it is coming from.
Is it also coming out of the exhaust?

 

Hello Sean,

Greetings from Chicagoland.

I'm sorry about the problem.

Is it oil, or is it coolant that is smoking? If oil/coolant is burning internally, it may be coming from exhaust-to-turbine ducting, if there is a loose connection. If it's external oil/coolant leak, the leak is leaking down onto the exhaust manifold/turbocharger area.

Many people have noted that if the engine is internally worn, it may be more economical to get a used engine (about $1500?) than to rebuild it. You could leave the current engine aside and find the problems & repair it later, then you have a spare engine.

That's all I can think of now. I wish you the best of luck.

yeah it comes out the exhaust when the engine is at high RPM and it smokes bad when the turbo is spooled up.

 

Is the smoke slightly bluish (I assume it is) or is it white or dark gray? Is coolant level stable?


JPN

 

If it comes out when the turbo is spooled up then I will bet it is black smoke.
That usually means it is running way to rich.

 

I know that it isnt black when the turbo is spooled up. It is definitly bluish and white. soo we'll see

 

Hi,

Just a quick reply, as I'm about to go to work.

You probably know it is the oil that is burning, if the smoke is bluish. Did you also check the coolant level in the expansion tank?

Will reply again after work.

Hi Sean,

The exhaust manifold is in the back of the engine and as they form into one pipe, it then connects to the turbocharger.Whatever the case may be, when bluish smoke comes out, oil is burning inside the combustion chamber. The following may be suspected:

1. Oil leaking from valve-train.
2. Oil leaking past worn piston rings.
3. Faulty head gasket.

Last time when the leak was repaired, the repair may not have been successful. Could you provide us with the description of the shop, as well as what they repaired/replaced?

Lastly, just in case check on the back of the engine, if you can do so safely, to see if there is a leak from the oil return line at the bottom of the turbocharger. Or you can just look on the ground to see if there's a leak.

Good day,


JPN
