Engine is 12.25:1 compression y8 fully built w/crower stage3 cam etc. etc.

Anyway a few days back it was probably 30-40deg out i had my bro start my car cold, there was no puff of blue but when i had him give it a few quick shots to 3k i could see a slight blue tint to exhaust.

After 2 minutes (i'm guessing once engine warmed up some? rings expanded?) it wouldn't do it anymore when revving and was normal.

Is this normal for cars on cold start? or on a high compression build? It was only a slight tint...

A compression test yeilded 240 across +/- 5psi

Please only post if you have some real insight or know if this is normal...

Thanks guys,
Vince
