Model T Ford Forum: Forum 2005: Cylinder Head casting flaw
Top of pagePrevious messageNext messageBottom of page Link to this message  By Steve B. on Friday, February 08, 2008 - 11:00 pm:

I noticed after cleaning my cylinder head of carbon, that there appears to be a casting flaw in the middle of the head between #2 and #3.Other than that it is in very good condition.
This is a high head for a 1922 T.
I used a search and found that others have found this with some heads.
The head gasket seemed to have sealed it for many years.Does this mean that I should be looking for another head?
I don't want to take any chances.
Thanks for any input.

Regards,

Steve Boothroyd

I did some more detective work.
I found the following regarding cylinder head changes on the MTFCI site;

08/15/17 T-401-C Cyl Head Added 3/4" cored hole between chambers 2 & 3.
So does this mean that some heads with this hole are considered correct, and it is not a casting flaw?

Good evening, Steve, without a picture I'm not sure just exactly what you're referring to... Many years ago, when I was working on the engine I got with my Great-grandparents '23 Touring, after having it boiled, I noticed a 'deformed' spot on the deck of the block, and a corresponding hole in the head and gasket. (This was in the back of the engine.) I decided that I would bore a small hole in the deck and help the cooling. I put the gasket over the block and used the bolts to center and hold the gasket and used a centering punch to locate where the hole should be with the hole in the gasket. When I hit the punch with a mallet, it didn't sound right, so I got a small drill bit and hand drill and ran the drill into where I thought there should be a small hole, and sure enough; there was already a hole there, it had calcified shut and just hadn't been boiled out. (This was my 1st Model T engine; I know such things now.)

Again, without pictures, I don't know what you're referring to, but is it possible that you're looking at a corroded or otherwise misshaped hole that has always been there?

...Just a thought...?

Happy motoring! :-)
