Hey Highside, the pics should be self explanatory but I keep looking at the plumbing and wondering exactly what is going on. The pic on the left shows the one way valve at the end of the short run, with the T going off to a long run of tubing to the tail or where ever, right? Which way is the one way valve hooked on, so that the crankcase can successfully suck in air on the up stroke? Is that what is making the system work without bogging the engine down?

Thanks,

Ernie
