im having some trouble with a persistent case of white smoke out of my exhaust. after testing my compression and blow by, i thought for sure that my turbo was blown, however, agp tells me that the turbo shows no sign of leaking oil or burning within the center housing. i really have no clue what else to check for or where else oil could be burning. my setup is a pfab top mount manifold, agp zeta 3.0, tial 38 and 2.5in dp. any informed help would be appreciated.

 

Are you positive that it is oil? The turbine wheel and heat shield were bone dry, and the turbine housing had zero signs of any oil passing through it. If the turbo were leaking oil into the exhaust, you would see standing oil or coked up deposits around the wheel. Even if the motor were burning oil we would see a little coked up oil in the turbine inlet, and it was dry. The turbine housing didn't smell like burnign oil at all, but you could smell gasoline.

You mentioned that the car is on an AEM running a base map, and the AEM was put in as soon as you installed the turbo. Are you sure it just doesn't need to be tuned, and you are just running overly rich?

 

Well for starters white smoke doesnt indicate oil.

 

ha didnt expect you to be on these forums it smelled like oil but i suppose i could have been mistaken. is white smoke indicative of an overly rich mixture?

 

Haha I have an S2000 too

White smoke is usually coolant.. but lots of fuel would be black/grayish smoke which may look white.

 

it's definitely white. if it's coolant, my headgasket is likely blown right?

 

If it is indeed coolant, you most likely would be having overheating issues or oil in your coolant too though.

I am willing to bet it's just too much fuel
