Default blow by help

i have a h22a4 and it spits out oil from the breather. i was thinking it has bad rings, BUT compression test it and the cylinders read 190, 185, 180, 180. im using rc 310cc injectors with a untuned virgin p28 ecu(for now) since thats the only ecu i have that is compatible with the motor. tried chipping another p28 ecu to a h22 basemap but it lags ALOT. if anyone knows what is causing this PLEASE HELP!! thanks

You can have bad oil rings and still get good compression. Did you check your pcv and make sure it's not stuck?

cheap fix, "Engine Restore 4cyl" or "cd2" @ parts store.

Tuning even stock motor helps.

mine are bad too : (

thanks for the info jprelude92. i added the 4 cylinder engine restore and installed my own diy catch can. i drove it like i normally do and it doesnt seem to spit oil anymore from the breather to the catch can, but there is still a tiny bit of air blow out from the other side of the can tube that connects to the intake. any inputs?
