Hey guys and girls, I currently have a rb25 that has been rebuilt from the ground up less then 1 year ago , the engine could possibly have around 15,000 on it now .
The issue I'm having is blue smoke out the exhaust ONLY when the car has been sitting at idle hot or cold for a period of 5 minutes or more . After a big rev it won't come back till it sits another 5 minutes or so . When driving the car I cannot see anything and my friend said he can't see smoke while I'm driving / thrashing it when he follows .
Engine currently makes 300rwkw on 18 psi and drives / runs smooth ? Should I be worried and what can cause this issue ? It's in no way blow by because my catch can setup is correct and has no traces of oil at all !
Some help with this situation would come in handy so I can stop chocking everyone out lol . Also forgot to say the car has not chewed any oil since service 2 weeks ago and oil is still gold .
