I think I will need to upgrade the breathers. I've got one on the valve cover and one off the black box, and I've got smoke through the exhaust.
To be honest steve my friend has run his 500whp ls/vtec for thousands of miles and never had smoking from crank case pressure.
Now could this be from something else? oil leak? etc....
maybe us hicks from the plains don't have issues with crank case pressure. but i would think one of the guys in town (2 300-350 whp, 1 400whp, 1 500whp) would have an issue if it was a BIG deal.
