But, when cleaning up the old orange cover to sell, I noticed that somebody closed the open slots in the top of the cover with duct tape! What was the purpose of their doing that? Am I missing a fundamental mechanical lesson? :rolleyes:
It is a 235 engine, cover simply bolts to the head, no top cap nuts. | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | I soldered mine shut and used a breather type cap for the oil fill so it would still breath. | | | | | Joined: Dec 2006 Posts: 1,154 Shop Shark | | Shop Shark Joined: Dec 2006 Posts: 1,154 | Its a PCV thing...they closed them up and used a non-breather cap and piped the cover to the intake manifold. I had the same thing, now this very weekend I'm going back to the road draft tube...PCV..or postively corrupt vituperation ..Steve | | | | | Joined: Sep 2001 Posts: 29,270 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,270 | 1954/55-1st non-PCV valve covers had 4 slits in them for "breathing" (and they used non-breathing oil filler caps). Later 235s valve covers had no slits in them (and they used a vented oil filler-cap on non-PCV engines).
It was common for owners of slitted 54-55 valve covers to cover/seal the slits (and use a vented oil filler cap) because oil leaks out the slits and looks messy. | | | | | Joined: Mar 2006 Posts: 483 Shop Shark | | Shop Shark Joined: Mar 2006 Posts: 483 | I J-B welded mine closed when I put a PVC system in my 53 3100 216 82 HP inline 6 low oil pressure babbit roded cast iron pounder.
