Intermittent oil burn Noticed past few weeks my car (r33 rb25det) has been intermittently burning oil, some days it wont lose any, others the oil level would have dropped by about 1/4 on the dipstick (this is with about 20-50kms a day driving). No leaks under the car, car doesn't blow smoke unless im under boost, after a cold start theres a slight mist but clears quickly. With a warm engine and in neutral holding at 2k theres a bit of smoke. Put a catch can in last week, havent checked to see if its caught anything but also havent really driven it enough, Car still pulls hard no power loss from what i can feel. Smoke is a light blue sort of color. Did a dry comp test and results were 135, 135, 120, 120, 135, 135. Put some oil down the cylinders for a wet test and results didn't really move. Results arent great but im not sure my comp tester is the best either. But either way im thinking possibly valve seals? i took the pcv out and shook it but only read recently to try blow it and see if it only goes one way or something? Only mods are 3" turbo back exhaust, and a FMIC. Using penrite 10 tenths 10w40.
