My problems started when my 16g died. I have a 2.3 liter stroker motor (500)miles on it. So I replaced the turbo and my car still smoked. Then I put a rebuilt head on my car. That head was either cracked or warped b/c my car was still leaking oil/coolant into the cylinders. Then I finally put a good rebuilt head on my car with a oem 4 layer mls. Now the car still smokes but my compression is 190 across the board. Also how long does coolant/oil stay in the exhaust.I have not cat just a 3 pipe from turbo to muffler.Any suggestions would be great.

 

It shoudn't take long at all to burn off. What color is the smoke?

 

The only time I have ran it, is to set the base timing. I want to pressure test the cooling system to see if it is leaking. This has been driving me crazy. I can't figure out what is wrong with the car. the smoke is grayish/white (i no that is the color for coloant)
Thanks

 

White is coolant
blue is oil
bloack/grey fuel

Try doing a wet compression test and cylinder leak down.
