Crankcase ventilation on a supercharged engine

Hi Ronnie,

Thanks for your writeups. I have teflon buttons and no wrist pin clips in my SBC. The machine shop I used built lots of race motors and he suggested them. He did all the blue printing and balancing and I did the assembly many years ago now :-)

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. ;)

I put an old fashioned curved valve cover breather on the right front of the oil pan with a baffle on the inside to keep oil splash away. Never had a problem with this setup.

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.

"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!
