I bought this 1931 and brought it back to La Vergne, Tennessee from Sioux Falls, South Dakota. It had blown exhaust manifold gaskets when I got it. I replaced with copper gaskets and no further issues there. However there is a knock. The person I got the truck from never mentioned any engine work but when I ran the vin I found a previous ad where that owner said the engine was rebuilt. Apparently this truck has gone through multiple owners in a fairly short amount of time. I have only driven the truck around the block. My previous Model A was a Tudor with a Antique Engine Builders motor with inserted bearings and this truck just seems to really vibrate compared to that car. It being new to me I have dropped the oil pan and started inspecting. I plastigaged the center main today and it looks to be within the limits. I don't see anything jumping out a me that would cause such a knock. Before dropping the pan I did run the motor without the belt and still have the knock. I can see that the #3 piston is different than the other 3. If anyone has any advice I'm all ears. Also if anyone recognizes the truck and knows the previous owner or owners please message me. Surely you wouldn't forget a motor that has so much chrome, lol. I have never seen one.

Here is a link to the engine running.
