do a compression test first. my turbo Colt blew white smoke from grenaded pistons and rings.

Well, after swapping in a stock 4G63T and going through all the California smog BS it was finally time to bolt on some power! I just installed an EVO3 16G, 3" downpipe, 650cc injectors, EVO8 Maf and an Eprom ECU w/DSM link. It fired right up and ran like a champ, until I stoped at a light and noticed it was running a little rough. It runs but it's blowing a ton of white smoke, not good! When I got home I noticed the boost reference line coming off the turbo had popped off. I don't have a boost gauge yet so I had no idea. Oh well, time to pull the head. It seems like I'm always doing something to this thing! |

Yeah, I know. I havn't installed the boost controller yet so I figured it would be fine. Go ahead and rub it in! |

white smoke? how about a valve job? try out a compression test and a leak down test before you yank anything out |

What does the smoke smell like? My car blew out white smoke when I was pushing oil past the turbine seal of the turbo, but it smelled like gas. Also, if you had a blown HG it would most likely push coolant under boost. If you have milky color oil then you have a badly blown HG, if you are just pushing coolant under boost then its just leaking slightly under boost. |

Thanks for the tips guys. The smoke smells sweet, it seems like it's burning coolant. I just checked the oil though and it isn't milky at all. Also when I looked under the hood the dipstick was out and there was oil blown out on that side of the engine compartment. That sucks! I guess it could also be the piston rings? Stupid question but how would a compression test determine if it's the HG or the piston rings? Maybe this post should be moved to the tech section. |

ok, if it's white and sweet, then that's definitly coolant... just a heads up. |
