What is a bobble rod? The old 216's and 235 were considered "babbit-pounders",since they relied on "spoons" attached to the crankshaft,for lubrication. The "newer" 235,261's,employed oil-pumps,ensuring better lubrication,resulting in longer engine life.there are plenty of rebuild kits available for the 235's. Try the links page right here on "Stovebolt".I'm NOT 100% sure on this,but I do believe that the 235 in the '54's were,in fact,equipped with an oil pump,so I don't think this "bobble rod" thing is a problem. If you're lucky,maybe all you'll need to do is drop the pan,check the pan for metal shavings. Check the rod bearings. The "bad" one(s) will have some play.Check crank for scoring, rub with emery-cloth. Wipe-down with CLEAN lint-free cloth,moistened with engine oil.Use a dial caliper for tolerance check. If crank passes tolerance test,install ALL new rod bearings per instructions,torque to spec's. Hope this helps.
