Model B pushrod sleeve update

Fredsjdb · Dec 16, 2014

Hi guys, well I picked my head up at the machine shop. I watched them do a magnetic check on the area that would've had a pushrod tube and it revealed there wasn't a tube. I took the casting number B2871R and did some checking and even though PC 330 lists that head and shows pushrod tubes, the same part number is listed in PC 264 for the single induction Model 50 and there isn't any pushrod tubes. Mike M you were right. It seems the late model B head didn't have any. Now I have to locate my water leak, hopefully it's the head gasket. Thanks for all the responses. Fred

Check your pushrod passages in the cylinder carefully. My 1944 B had a crack in one of the pushrod passages in the block, leaked water into the oil. Crack was caused by freezing, but there were no other cracks in the block.

It is hard to seal up those heads sometimes. Not much gasket area at the top and the gaskets now don't have crimped areas around ALL the openings like the really old gaskets did.
