Hi Guys, I had my SR20DET rebuilt in my 180sx less then a year ago with all new internals including new pistons and piston rings. The engine has only done around 6,000ks. I have noticed that there is what looks like smoke coming out of my breather filter that's connected to my oil overflow can. I have been told its potentially blow-by or something to do with the crank case pressure caused by the piston rings not sealing correctly? I'm just wondering if I could get some more opinions. Just some things I should note: - The engine doesn't blow oil out of the breather just smoke. - The breather has a hole in one end where the smoke is coming out (its not closed off) - The dipstick doesn't pop out. - When I take off the oil filler cap when the motor is running it feels like air is coming out the hole. - Engine performs great. Any advice would be appreciated thanks.
