Model T Ford Forum: Forum 2014: Lost an ear on the head

Bought the engine that way, the passenger side ear of the coolant port is gone. I'd rather not replace the head. I was thinking of putting a threaded tab under the head bolt that is right there and attaching it that way. There isn't a lot of stress, it just needs to keep the water in.

Thoughts?
cheers,
chriso

I'd replace the head. The tab idea may work, but for how long? With all the vibration and twisting going on, I would rather have a good surface to work with. Besides, it would be a good reason to get a Z head.

Used stock heads are plentiful with lots of us buying Z heads. I have 2 or 3 of them lying around here and it's not easy to sell one - you almost have to give them away.

I'd say get another one, or as John said above, this might be a good time to get a Z head.

Chris, that threaded tab idea should work, give it a try, easier than R&Rng the head.

Chris: You didn't say if you need a LOW head or a HIGH head. I sometime have as many as 50 high heads. I think I am down to 20 HIGH heads now. I use some of them for weights when I irrigate. I sell HIGH HEADS for $25.00. I am out of LOW heads. Shipping will be high, $18.35.

So that this doesn't happen again soon, the usual reason one of the ears breaks off on either the head, the water outlet or the carburetor or other such location is that the old gasket is not completely scraped off. This problem with torquing the bolts unevenly will put much pressure on one side leading to the "snap". I realize this won't fix your head, but maybe it will prevent you or someone else from such an experience in the future. When you scrape the surface and install a new gasket, turn each side just a little at a time alternating the pressure until both sides are equally tightened.

Do not forget that adding anything under a head bolt will change the thread engagement (length) of the head bolt. They are "border line" anyway and can strip out if not carefull.

U pay shipping and I'll send you a head...It may cost less to get one from Dave though. Colorado is much closer.

Thanks for the replys! I'll look into getting a new head. I'm erluctant to get a z head right now, mostly from cost, but also I don't know how well they behave with iron pistons.
