white smoke

[gt7877]

Dear

I have turbo frs

From the first tune (Dyno tune)

To the second remote tune (online)

I noticed that when I put gear for example at 3rd gear and rpm

Lower than 3k some withe smoke coming from exhaust .


What could be the issue ??
Thnx

White smoke is coolant.
Blue smoke is oil.
Black smoke is fuel.

White and Blue smoke look similar. Have you had a chance to smell the smoke. Coolant will have a sweet smell, oil will smell like.... burned oil.

yep thats coolant so your either cracked your block or blew a head gasket

Nooo

This happened just at high gear and low rpm


Coolant level is good all the time

Also oil level is good

have you tested it to make sure? it might be a very minor leak under high load. does the smoke stick around or go away pretty fast like when you start a car in the cold?

My dear

This just happened at low rpm

Or when I shift to reverse .
Just for few seconds and gone when rpm go up





I think it is maf scaling issue



Steve any thing from your side

Very unlikely to be a tune related problem unless it was black fuel smoke


Smoke is most likely oil, but possibly coolant


Coul be turbo seals
Catch can routing issue
PCV vavle or check valve issue
Rings valve guides worn broken
Overfilled oil


Blocked or restricted turbo oil return






Check turbo intake for oil



Overoiled air filter




Probably a few others


It only takes a small amount of oil to see smoke might take a fair bit of driving before you see levels drop.
