Crate LS-3 PVC valve! LS3 525 Connect & Cruise.
The paper work with the GMPP crate engines is poor at best! I'm not sure what's up with the PVC valve. It has a 2 pin connection but I don't have anything on the wiring harness? I'll take another look tomorrow, did I just miss it?

Al - PCV or the evap canister pirge valve? My LS3 crate has no PCV valve - just a little “loop” connection between manifold and lifter valley on the passenger side just behind the DBW throttle body. Flow is controlled by an orifice in the make up air line which connects to my passenger side valve cover. On stock vehicles the purge valve is cycled by the ecm. But on most swaps that function is turned off in the ecu, and the vacuum source is capped. If you’re not following I can attach some pics. If I’m not following, you’ll fill me in.
