I would like to thank blown for helping me out! I drove all over today with no blow by anymore!!! Heck yes. And LSf-150 mine put down 460/503 on 9lbs with 13 degrees of timing. It's got a whole lot more, i just wanted to keep it very safe and too last a long while!

 

Great

 

Guys i now have ran into another problem.. Or am i just freaking out too much? Well here it is. My AFR on my wideband now reads from 11.0-11.2 at idle? That seems super fat to me.. Before i install the check valve it was running 14.5-14.9 at idle. Will this hurt my truck driving it for the weekend till i get bck to the tuner Monday? He said it's from the motor being able to breath now since it doesn't have crankcase pressure that it doesn't need as much fuel as before? Some one please help asap
