S4 NA FC

just removed all emissions, OMP, , TB mod, etc and was not clouding prior to removal

Any suggestions....I've been reading that white smoke is usually a blown coolant seal, bubble test seem to show otherwise

-rear upper and lower spark plugs were caked with wet oil
-loss of power throughout powerband
-compression test probably tomorrow

cloud of white smoke:


coolant neck same run:

 

had vacuum leak on the EGR block off plate which was sealed....idles perfect and TPS setup

 

If the coolant seal is blown at a point in the housing where the rotor is on the intake stroke, you probably won't see bubbles in the cooling system, as water is being sucked in, and no pressure being forced out. Just an idea.

 

is there any other way to test it?

 

I think there are tools that you can attach to the coolant system and pressurize it to see if it leaks.
