Sorry to be off topic but I didnt wanna start a whole new thread, and Z32 has the same blow by problem. Well here goes:
My car had a really bad case of Blow By where it was smoking (bluish) out the exhaust at anything past 4000RPM and a fair bit too, cause I would look in my rear view and the cars behind are engulphed in it, and there was oil seeping out of the boost controller.
I ran it for around 1000kms really easily (nothing over 3000rpm) and it seems to run really really smooth now, no smoke any more even to 6000rpm, I was contemplating doing something about it, but should I bother now?
