I have a '59 283 w/ 670 miles on a rebuild by a supposedly reputable shop. It originaly came w/ a road draft tube. I used the '64 pcv hose hookup that replaces the draft tube at the top rear of the block. It was from an incomplete parts engine, so i don't know which (if any) pcv valve was correct. I used a pcv valve in a blister pack from the parts store because it had the right threads for the carb base, and was the right hose size (1/2" i.d.). The valve is installed in the correct direction, I gave it the suck/blow test and it functions correctly. It only smokes a little on start-up.I'm using a quart of oil every 80 miles, blow-by rolls out from under the hood at the stoplight, there's oil spatter on the firewall (vented oil fill cap), the rear main seal leaks, all symptoms of a pcv problem, or rings that never seated. Do different valves have different cfm flow? which one's right? are my rings FUBAR?
