| Oil catch can / plumbing... |
Subject: Oil catch can / plumbing... by Schrade on 2016/4/17 19:55:08 Do you have one? Pictures? How do you keep it from filling? '90 LT-5 was assembled without valve stem seals, and I got an oil burn at startup that has always bothered me. Even after 10 minutes restart, I get the blue puff. BESIDES that, PCV pull a LOT of oil. When I did top end rebuild, I pulled the TB after half dozen Closed Loop idles, and saw a pool of oil inside plenum, at the PCV-to-plenum inlet (Yellow Circle). I wouldn't have believed how much oil PCV pulls otherwise. So ideally, the PCV inlet should be routed in FRONT of air filter, NOT behind TB. But how to maintain vacuum? How to seal the hose??? Otherwise, an oil catch can for LT-5 would need a drain valve, opened when motor is OFF, that would allow the oil to drain BACK to crankcase. Motor vacuum would keep the valve closed for proper operation while running. Thoughts? Ideas? |
