The Project Pad

Well, as anyone could have predicted, the 25 year old check valves in my 20vt swapped 80q have failed. Does anyone have any BTDT on what is a good one to pick up? I was looking at the ones on silicone intakes, but wasn't sure how well they would work. The price is very reasonable, and they come 10mm and 12mm versions. Also, can anyone tell me what size I would need.

Thanks

I feel stupid asking this but where are there check valves in the 20vt system? Unless you're talking about the one right where the locking diff controller taps into the intake system? Not even one in my CCV system

McMaster and they have cad drawings so just measure and match

Im not sure where that are in a factory 20vt setup, but my setup is using a JT head with a vacuum pump and vacuum boost brakes. I have 2 check valves in my setup, one right before the vacuum pump, and one in the booster.

Thanks Shawn, I'll check into that.
