So behind the scenes I have been struggling with the PCV plumbing. I am fighting a oil leak from the back of the motor.
For now I am going to vent the Oil Fill Cap and do version 5 or 6 of the plumbing.
I walked into the needed size by using various drill bits.
Final hole with drilled with the correct bit for the needed NPT tap.
My neighbor Sean cleaned out the tiny pieces of aluminum.
Fitting going in.
Over the winter I am going to pull the intake manifold and install the LS1 Valley cover with the PCV plumbing in it.
