Crankcase ventilation on a supercharged engine

I also recently looked into vacuum pumps for the oil pan especially the electrically operated ones but they are big bucks!

Your Welcome.
Teflon buttons to keep the wrist pins in place have been in a few of my flathead builds over the years. Also added teflon buttons into the piston skirts back when I was using Jahns brand cast pistons. Those engine's would rev really nicely but I'm not sure if it helped with economy.

Hi Flathead,

I see that your avatar engine has a blower. Have you used this oil pan vent with a blower? I've thought about doing that too and even to plumb it so the breather was high up like around the top of the heads.

Yes it is on that engine, has been together at least 30 years.

Great, it must be fun!

"I know that a guy must take his crankcase ventilation pretty seriously to spring for one of these "SPENDY" adjustable PCV Valves. Does it deliver anything like the results that you had hoped for, Glenn?"

I went for a good test ride today and the Wagner PCV is really doing the job. No oil was pushed out today!
