Ok so about a month ago I started my car and there was tons of smoke coming out of my exhaust (oil being burnt off) and leaking out my turbos. I asked around and everyone basically said my turbos were gone. So I replaced them with my friends (working fine when they were on his car, had half as many miles as mine) and I am still having smoke issues. So I replaced the PCV valve going from the oil fill to the UIM. I went to go drive around to see if the smoke would go away and now my coolant light comes on, my engine temp is immediately at normal running temp, and after about a minute of driving starts to over heat and almost go into the red. I stopped driving immediately after it started over heating. The engine bay didn't feel very warm at all. I filled the coolant back up after swapping the turbos until it started leaking out of the over flow. Does anyone have any ideas?
O great! That sounds like a blown coolant seal to me. But maybe not, I guess you have to check for the champagne bubbles or whatever. Do a search so you can see if thats the problem.
If you think its a coolant seal because of the smoke, the smoke is oil burning not coolant. The coolant level was fine before I replaced the turbos. I lot of the coolant leaked out when I replaced the turbos, I didn't think to drain the coolant before pullint the coolant lines of the turbo. Also the car feels fine, the idle is a bit lumpy like when the car is still warming up and drives just fine.
Could it be the wire for my coolant sensor, I noticed a plug by my slightly above the oil pan on the drivers side where the sire had come out of one of the plug connectors. Is that for the coolant sensor? Would that make my temp gauge look like it was going to over heat?
If your temp gauge sender wire was disconnected, the gauge wouldn't read at all. Think about this: you have overheating issues, because not only does your temp gauge go sky high, but your coolant system is boiling over. I'm hoping that you replaced the coolant that was lost when you replaced your turbos before driving around.
Did you burp the coolant system after replacing the lost coolant? If you have a lot of air in your coolant system, it won't pressurize to the proper level, and will boil over more easily. However, it still appears you may have a major problem. Search for burping the coolant system, then do the "champagne bubble" check in the filler neck to determine where to go from there.
If the coolant is not circulating, it will take only a few minutes to boil the coolant in contact with the engine housings. Make sure you get all the air out of the system by burping as mentioned above. If you have a lot of trapped air, the coolant may NOT circulate.

Well its been a while and not much has changed. I was able to fix the coolant problem (air in the lines), but was unable to figure out what was causing the smoke. I drove it again in December when I was back from school and still smoking quite a bit. I am curious if it might be the oil seals in the engine or and this is just a guess cause I am no oil expert, but could the type of oil used have any effect. This happend a few months after switching to pure synthetic oil. I will try and couple video's posted of what it looks like. Any good places to post, with out have to sign up for something?
No collant level hasn't dropped at all, oil however has lost a few quarts, I think if I go home for spring break I will be doing an oil change (more like adding oil to an empty engine), and try to see how much exactly it burns. Can anyone think of any problems that might be caused to my engine driving with such a condition. I am to the point where I think I need a rebuild so I am not to worried about "blowing my engine" but want to cover all my bases, and if I can avoid needing to purchase extra parts for a rebuild I would like to do so.
Check the charge pipes coming off the turbos before and after the intercooler and see how oily it is. Extremely oily meens your turbos are leking oil or yourPCV might be wrong or in backwards possibly CAUSING OIL TO GET SUCKED INTO THE TURBOS.OOPS CAPS. It might just be the turbos oil seal at the turbine side also that is causing oil to leak into your exhaust.
Oh, did the overheating issue get resolved after burping the coolant?
