Re: Continuing engine problem
On radiators. Sometimes a radiator can perform exactly as new and still overheat. The reason for this is, the tubes are soldered to the fins for heat transfer. On a radiator that is 80/85 years old, this solder joint can be compromised and broken loose. The result is an invisible problem for heat dissipation and overheating. A new radiator should solve this problem since I know of no way to re-solder the fins and tubes.
FWIW.

Re: Continuing engine problem
"Too tight" has always caused two (2) types of many past Model A mechanical failures"
"Too tight" to pay for qualified professional engine re-building services is usually the most common one." This is exactly right, HL I can't imagine getting an engine from a rebuilder that told me it's going to be real tight, until it's broken in. Rediculous. |

Re: Continuing engine problem
Didn't the factory set up the bearings somewhat close and then run them in on a jig powered by an electric motor until freed up?

Re: Continuing engine problem
If I may.. there was a post awhile back that eventually centered on pistons, made overseas that many of the vendors were selling. There were many failures. Modern engine re-builders buy parts from manufacturers who specialize in what they do. Most of them have dropped model A pistons because the market quantity isn't there. Now we have products made by shops overseas filling a void that they know very little about. So, who now makes pistons that work well for our old fords? Look closely at the skirts, both inside and out for a company's name. I suspect that there won't be any. This may be the key to your problem, and that does not, in any way imply that you don't also need a radiator.

Re: Continuing engine problem
Dudley, those two statements are correct. It's part of the mystery. But all will be revealed. Or not.

Re: Continuing engine problem
Chuck, "why" is the big question. See my OP #1 for details.

Re: Continuing engine problem
I've seen this a few times, many years ago. The machine shop gurus said the reason it doesn't seize up when running is because the engine has enough power to overcome the tightness, but once stopped the pistons and the block glom together and then it's almost impossible to turn over until it cools down.

Re: Continuing engine problem
Motor looks dry. Take a look at the Oil pump. Might not be putting out enough flow.

Re: Continuing engine problem
I don't think so. The Model A is not a pressurized system, it's a splash system.
