30dodge35 Posted May 7, 2015 Share Posted May 7, 2015 Question and opinions on older engine crank and piston journals hardness, I have had this happen twice on 35 and 36 dodge engine , the number 6 piston journal will egg shape and loose oil pressure. Then engine develops a knock. After tear down ,both times number 6 journal egg shape and worn, other crank and piston journals are OK. I had a old dodge engine mechanic tell me to get a 38 crank or older, due to the fact the journals are shot peen. I have since then put a 1940 Plymouth engine after rebuild , it is working fine!! Many miles on it and still great oil pressure ,no knocking. Jesse Link to comment Share on other sites More sharing options...
