The Stovebolt Site Forums The Shop Area General Truck Talk Re: What did you get done on your 'Bolt today?

Valve adjustment. The engine in my '53 is a '54 235, originally passenger car service with standard transmission, block serial number suffix F54Z.

Two good surprises: how clean the inside is - first time I've had the valve cover off this engine - and (interesting surprise) that the head has a '55 date code (see photos). I don't know too much about the engine's past history, other than it is not original to my '53, but it appears this engine doesn't have too many miles since rebuild (and maybe explains why there is a '55 head on this block). The head is a little-documented casting number 3837161, which appears to be a '913 variant.

Not so good, although not a surprise - the valves were all over the place before adjustment. Some intakes very loose. Two exhaust valves too tight. About par for the course, I'd say.

Used my new to me, vintage Plomb valve adjustment tool (3rd & 4th photo). Worked like a charm.
