Rear Main Bearing

[rjhink]

Is there a supplier that has replacement rear main bearing drain pipes? I have a '34 V8 engine with an unvented block and would like to install a pipe since there isn't one currently in place.

I can buy some pipe and a die from MSC, but it would cost far more than just buying a pipe . . . if I can find one. I've only been able to find pipes for '30-'31 Model A and '39-'42 engines. Given that this is the only flathead I've ever owned, I don't know if either of the above would work.

The question is when were they made?

From various reports, parts known to be made after production are not made like production era parts. They may have been done by contractors and not up to the production line standards.
I have some later Ford NOS rods and they are not +-1 gram the correct weight. I know of people with NOS flywheels that were not balanced and were known later production.
So you need to know more about the parts you have and be careful. Also Ford was known to not waste stuff. So parts that would not be used on the line cause something was off might be sent to the dealers for parts stock.

Anyway, stuff to consider.

There was a recent discussion here that Bill Barlow has stopped doing the bearing rebabiting service, a real loss.

As this a V8 the main thing will be the length of the pipe correct very important give Mac Van Pelt a call he will give the length
