Im new hea, just bought a r32 skyline with a rb20det. seeing if anyone knows whats up with the motor. it runs fine except blows alot of smoke on startup, also when i stop and pop the hood after hitting boost the oil catch can is filled with oil. there is a mist coming out of breathers all the time when the engine running at low rpm even, also it has a ticky sound coming from the motor im pretysure its a rod bearing? any help would be greatly apreciated.oh yeah, also idrive it about 2km frm cold and its at just over half temperture is that normal for a det?
