1932-1934 4 cylinder questions

[poweredbylincoln]

I posted this on the early v8 forums.


I am working on a 1933 pickup with a 4 cylinder. The big water jacket above the water inlet on the side of the motor has been welded shut and machined flat. With the letter F stamped in it

The old head gasket has the water hole in it. The new gasket is solid without a hole

Any idea why it would be welded shut? Besides an old overhead conversion?
And why the new gasket has no hole in it?

I am thinking of re drilling the block and gasket to let the water go through like original

Or is this original or a modification to the block?

There is no hole in that location on the B engine block. There is a hole on the head side for casting reasons – it helps get the sand out, or something like that. The corresponding surface on the block side tends to erode over time, especially if there's a hole in the head gasket. Looks to me like someone welded up the eroded area and machined it flat again.

Thank you for your help. I really appreciate it

Leave it as-is.

Here are pictures of a stock Model B short block. This engine was built after 1934 by a non-Ford casting house as evidenced by the "Diamond" casting mark on the block. Jim Brierley is correct, do not drill a hole because there was no hole there originally.

Bob, are you sure that is an stock Model B? that rear main looks funny.

Looks like someone got creative in dealing with a rear main leak on that engine by adding extra drain plumbing.

The rear main is funny. It is a farmers idea to cope with oil leakage. This engine came out of a tractor. The extra drain failed to make a difference.
