I opened the valve cover again to do the cam : jwt s4
Valve cover decided to crack. I think I over tightened the npt barb fitting.
Luckly, I had an extra valve cover but I had to have my welder weld in a bung for crank vent hose.
I then took out the maf and put in gm 3bar sensor along with gm ait sensor for ease of tuning.
Wired up 6 sensors (4 of them had to be lenghtened like picture) for Defi advance ZD. Hopefully this will save me from engine trouble in the future (knock on wood)
Mounted oil catch can and moved the intake down low.
