Noisy '46 Engine - 01/28/12 08:17 PM
My '46 Chev, with restored engine, was running like crap while at Flint. When I would accelerate the engine would sound like it was coming apart - with considerable valve noise. Thinking I had sticking valves, I tried the solvent trick to no avail so finally pulled the head when we got home. Only thing engine shop could find wrong was the oil deflectors "hats" on the end of the valve stems were acting like hydraulic lifters - so they machined a flat on the side of the stem to help release the oil/air. This fix didn't really didn't help much. The engine idles smooth, after adjusting the carb float (thats another story), although you can hear random ticking now and then. Question: Is there another form of oil deflector, i.e., rubber boot over the valve guides or o-rings on the stem, that I could use to eliminate the metal "hat" deflectors?
I had another '46 back in the late '70's and early '80's that had a whisper quite engine. I can't remember if it had the metal "hats" or not.
Thanks in advance. Alan
