hey guys i have just put an rb25 into 32 it runs great lights the wheels up way easier than my 20 and the torque down low is great!!!
just one problem, it blows white smoke on idle, decelaration and if im going up a hill under heavy load but it will stop once boost hits.
if i rev the car to 2000rpm from idle and hold it there i get zero smoke until i let off.
if i really hammer it hard and then stop i get crazy amounts of smoke, if i drive normal i still get some though it would pass as condensation smoke but its definately not
i have checked compression 125,126,125,126,129,129.
i pulled off the dump no oil and not much shaft play, cooler piping return is spotless but there is a slight film on the other side which i think is normal.
i blocked the PCV and intake and setup a vent to atmo catch can, no change.
spark plugs all look fine, no ecu errors.
no oil in water or the other way around.
smoke smells like normal exhaust smoke i guess, definately not acidic like it was when i did a head gasket
i have only driven it maybe 100k's so hard to say if its using oil..
the engine was refurbished(rings, bearings etc) about 3-4 years ago it then did about 15000ks after which it was pulled out of car and sat around for a year, the head was pulled off and checked new valve stem seals were installed and the engine was put back together it sat around for another year then i bought it and installed into my 32
any ideas on what i should try next??
