AIR System questions?
Went to replace the T piece that joins the left and right side hoses from the exhaust manifolds to the Electric divert valve. Thought I would check to see if the check valves were operating correctly as per FSM. Started the car up, minus the T piece, and both left and right sides are positive pressure to exhaust. My interpretation is that they are a one way valve for fresh air to be pumped in. Not allow exhaust to be pushed out. Has Watson headers on it.
Is it an emission system that needs to be working ? or can I bypass it ?
