I've made a couple posts before about smoke from my 87 Turbo II. I was confused about whether it is a coolant seal, or my turbo that is gone. Well it only used to smoke when I let off from high rpms. Then a few days ago it smoked a bit on startup after I filled up with gas. I put some radiator seal stuff in my rad and my coolant light no longer comes on.....this is good. But the car still smoked. Now today I was idling at a light, and it started smoking(a couple times it did this). Anyone know what is up with this? It is a whiteish blue smoke by the way.

 

Smell it. Sweet = coolant. Its probably burning oil though.

 

im thinkin oil...my N/A would start smoking climbing in the revs after 5k, and if I let off above 5k...Check your oil lately? See if its getting low...Mine would eat a qt or 2 every week...

 

oil seems to be holding up pretty good....i add about a 1/2 liter every 2000 k or so(between oil changes) If my engine was gone would this cause this? Or is it more than likely the turbo? The engine is a rebuild about 20000kms ago(no receipts given but a comp. test showed about 7.0's all around. The turbo is original and has 215,000kms on it(130,000miles about)

 

What radiator seal stuff are you talking about? Could you explain it. From what I have read it sounds like a band aid fix to possibly a bigger problem with the radiator.

 

Prestone® Stops Leaks

Prestone® Stops Leaks is a high quality performance product consisting of pellets suspended in a corrosion inhibiting liquid designed to seek out and seal leaks in your radiator, heater and hoses. Pressure caused by the leak causes the sealing particles in the pellets to press against the damaged area creating a seal. Prestone Stops Leaks also helps lubricate the water pump while providing protection against rust and scale.

That stuff. My radiator is f*cked anyways so that's not a big deal. But my cooling problem is fine right now, it's the smoke I am worried about(turbo?) I would have fixed the cooling problem better, but I just moved and am short on cash......this seemed to work excellent so that's fine by me.
