Hi All,

Anyone experienced blue smoke in the exhaust after tracking the car? The track I went has some elevation change and two other NA BRZ/86 has similar issue after 2 sessions as well. Two mechanics at site suspect that it is the PCV issue.

I have a catch can already but we think the oil somehow suck back in to the engine (due to the g force?) but not 100% sure. The blue smoke on my car is relatively less than the other two 86/brz. After driving on the hwy under 4k rpm for 30 min, all the blue smokes are gone and things are back to normal.

Any suggestions on how to prevent this?

Thanks!
