The check valve for my vented optispark is stuck shut. The only way to get it from GM is to buy the whole vent line harness which is like $40. Does anybody know where I can get a 1/4 check valve??? Allready tried Lowes and nothing there.

AUto parts stores should have some. Go to the "HELP" brand section. It's more or less a filter.

Bound to be some people that have replaced the vacuum harness that might have one of those lying around.

Let me know if you can't find a suitable replacement. I snagged a complete vacuum harness off of a Fleetwood at LKQ on 70 the other day. It was in such good shape I couldn't pass it up for 5 bucks... I do know that the check valve makes air flow through these things tighter than you might think.

have you tried to clean it?

i need the whole harness myself..
