crankshaft bearings

Two other places I found that killed some oil presure was the rocker arm 
bushes and /or shaft itself,---------------Also , I learned the hard way that 
connecting rods have to have round holes, not elongated  ones. I once just 
put in new rod bearings during a quick weekend rebuild and discovered later 
that I should have had the con rods resized.--------the above just my 2 cents 
worth,--------------Bob Chamberlain
