blowby, how much is too much?

Sort of off topic but i got a 4cyl carb motor (just think of it as a low po 6 with 2 less cylinders for this question) and i have some serious blowby coming out of the valce cover filler hole. Its enought to float a ping pong ball on! Im wonderi g how much is about average

?

By any chance do you have a 2.6 Mitsubishi Jet engine with complicated reed exhaust recirculation? If so it has a pressurized crankcase, and pulsating air mixed with droplets of oil blowing out of oil fill opening in valve cover when running is normal. I have owned one from new in my 82 LeBaron.

I get a little smoke on ckoked cold start for about 30 seconds

Is it making bluish white smoke, or black? If it is black and a carbureted 2.6, check for a stuck “Sub ERG Valve” located in base of carb activated by throttle opening. My ‘82 LeBaron suffered long chugging rich starts for years (600 summer miles/yr for the last ten or more) and I thought it was a choke problem, but a timing chain replacement project this winter reviled stuck sub EGR.
