I have a Lyc IO360-A1A 200 Hp with a sniffle valve that gets stuck open. It will close while cold but will not seal tight when hot. It will work when you blow through with your mouth but I think it requires to much vac to close. The idle is really bad with this leak. I can not richen up enough to make up for the leak and smooth the idle with the servo set correctly.
What is the down side to not having the valve in place. Will a normal check valve work? How about a auto pcv valve?
I noticed several Mooneys that had an open drain and a restrictor fitting with a hose. If I set the idle mixture on the servo correctly with the drain hose open will this be OK?
How much fuel can return to the plenum after shut down and shouldn't it be evaporated while the engine cools down. 100LL flashes off fast.
Thanks
