I just dragged home a new vehicle: a 1953 Willys Overland Pickup.
Stude Content....I think that Brooks Stevens was the designer of the truck????
I think the original engine was an "Intake Over Exhaust" (F Head); but it was underpowered, and often replaced with "More Stude Content" the Stude V8, or the Flat Head Ford. Mine has a Mercury 255 cid (stroked version of the old 239 Ford FlatHead); but it's stuck. I just pulled the heads, and number five is a little cruddy, and the PO has used two head gaskets on that side. There is indication of coolant leakage at number five (and possibly some at number three).
I'm now soaking the cylinders with Rislone, and will rock it daily for the next week or so.
Thus far I haven't been overly aggresive in trying to free it up. I'm just rocking it; and seeing some movement of the fan (indicating movement of the crankshaft), but so far no movement of the pistons.
Any suggestions?
Thanks; Keith.
