So my long tome friend that i havent seen for a while, paid me a visit today, he drives an EVO 9, MOD list is

fp red
injen pipe kit
injen intake
full turbo back
880cc FIC
ARC intercooler
walbro 255

The problem is is blowing WHITE smoke from the exhaust at idle + at WOT is ALOTT! of it. I heard it could be a Blown HS so I checked the coolant level and its fine, Oil level and its fine too and NOT "chocolately" or with bubbles . He told me everything was fine, until a shop intalled a mishimoto radiator, after that it start to act weird and then smoke came.

we check for any boost leaks and found a few disconnected, we plugged everything back and zip tied it, but it still doesnt, could it be a bad PCV?

thanks for ur help guys

 

A lot of white smoke on throttle is deffinetly internal. My buddy had a similar problem and it was his rings. I'm going to go with That with you but its hard to say with no video. What's the smoke smell like?

 

smoke has a BURN smell, when is idling u give it gas and smoke comes out too, and like I say at WOT is ridiculous. We checked the spark plus too but they just have the normal wear

 

Check your turbo too. I had that situation with my DSM and some guy told me it was probably the piston rings. Once I pulled the intake off however, I noticed the turbo had a huge amount of shaft play. Replaced it with a larger one and never had anymore smoke.

Moral: don't let mustang builders/tuners diagnose your car lol

 

I'm sorry to say, but all I can think, and say is it would be piston rings.

Also 1 more thing is the oil level going down aswell, or does the level stay the same?

damn :/ we just checked the turbo right now and its pretty clean with NO shaft play at all, the wheel turns really smooth

 

oil and coolant are clean and at their level :/

 

white smoke is water--- or coolent.
grey smoke oil
blk smoke too rich..
sounds like you blew a head gasket. check radiator for bubbles while car is running or if you see brown sludge/foam around the oil cap.

 

White is probably coolant

 

on idle there like white residue around the inside of the exhaust tip, if it helps on anything

 

If the plugs were dry it's possible its the turbo. Ill the lower intercooler pipe off and check if there is oil in the pipe.

mmm we cheakd under and around the turbo is a little wet from oil, maybe a seal? but wouldnt it be the smoke a diff color? if the turbo was burning oil?

 

normal driving theres no smoke, just when boosting, but checked for shaft play and their none, turbine looks clean,

 

It would be blue/white
