Need valve adjustment procedure for a friend's '55 1st 235. I assume (but do not know for sure) that the engine is original to the truck. Is there an easy way to tell if the engine is equipped with hydraulic valve lifters? These are his original comments about his engine:::::::::: Developed a knock in the '55 engine and seems to be located in the rocker arm area. The small diameter upside down "u" pipe has a hole or split on the underside top that leaks oil when the engine is cold, but not after it warms up. Should that hole be there? Second, there doesnt seem to be a whole lot of oil in the rocker arm enclosure, in fact doesn't splatter out when reving the engine with the cover off. Should this area have alot of oil or just a heavy film on the rocker arms from the seepage thru the little holes? The noise or knock is pronounced at a very fast idle and is not hardly evident at most other engine speeds. :::::::::: end of Charley's comments I had Charley use a hammer handle to press on various moving pieces and look for a sound change. He said "On the second and sixth rocker arm adjusting nuts. The sound was loudest on the glass bowl of the fuel pump, so I removed it and took it to NAPA who will have a new one here Monday. If that doesn't solve the problem, at least I will have eliminated a "possible cause for $20." Any comments from the Peanut Gallery?
sounds like you may have a small end gone or piston slap, when you give her a rev and off the gas does it only make the noise as the revs drop or as they rise too? ________ HEALTH SHOP
Hey Bill, long time, no see! If the weather ever cooperates, let's meet up again at Kroger's. Here's my thought: Go to www.speedprint.com/Deves50/valveadjust.php and read Nate's very thourough article on valve adjustment. If that doesn't quiet the nosie down, try slowly pouring a can of Marvel Mystery Oil down the carb while maintaining enough RPM to keep it running. I swear by the stuff. It kept my '72 chevy nova running thru thick and thin for 7 years. If you'll recall, those were the days of the notorious "power knock". Let us know if that works. If not, the Master will tell you what to do next! Nate, are you listening?
Without actually seeing said engine,no way I could give you a diagnosis,but there should be lots of oil flowing from the rocker arm train and the "upside down" pipe you mentioned.
