after the car runs from a while, a greyish white smoke comes out the exhaust. a noticable amount. after boosting the car hard tonight, it starting coming out a lot. The car is having trouble boosting, and makes a terrible "moo" sound when letting off the gas.. It has a removed air pump, so its a different moo sound, and its non sequential, so i dont think its a vaccume problem. any suggestions, or ways to further act on this problem. any help would be great

...wait, did you jus say your supra made the sound of a cow?

 

rx7... this is the mazda section man

 

 

if there is excessive air "whoosing" noise when they are spooling the turbos could be on their way out. I know when I had my old s4 turbo on it sounded like it was spooling 16psi but it was only doing 6psi. There was also little deposits of oil and with all my emissions removed there was no way for the oil to get in the cold side except through the seals. Usually the twins crap out around 100k miles if properly used, i.e. boosting the crap out of them

 

sure there are no boost leaks? especiall in the elbows if u got the stock cooler. pull a intercooler pipe see how bad the oil film is.

does it smoke right when you get out of boost? but yea i am in a smilar boat waiting for mine to get bad enough to replace

 

i pulled them off, there is oil in the coolant, and in the y pipe, im just gonna junk them..

 

oil in the engine coolant???

 

You get it fixed? I coulda sworn that was you I saw today on Mariner in Springhill. It was around 9:00 or so....

 

haha nope wasnt me... deff wont be "fixed" for a while...
