Simple Questions...Hopefully

I'm gonna do a compression leak down test today, so if all my cyclinders check out okay, can I conclude that (1)all of my valves are okay (2)and my piston rings, and (3)the only reason I'm getting oil in my intake manifold is probably from blow-by coming up the PCV?

Thanks
Dave
 
Yeah I'm doing some research now on the DIY pcv oil seperator set-ups. I can't see spending $60 from Steeda when I can buy simple parts for $20 and build my own.

There's a bunch of write-ups on here, does anyone have experience with one that works better than another?
