It was the 1/4 hole between pistons 3 and 4 that was not drilled out fully into the water jacket. On my second HC head, a different 1/4 hole was not drilled out.
Back 2 pistons (3 and 4) were scored. The scored areas face each other and both face the divider between cylinders 3 and 4 where...
I had a blown head gasket soon after my motor was rebuilt. I replaced it, and soon had a scored piston. When we took the engine back apart, I noted the water hole passages were not drilled all the way through the casting on the new high compression head. I am not sure if this was a...
Lot 51 shows a 1931 Tudor sold for $25,300 yesterday 1-15-18 at Scottsdale.
Nice looking mostly stock car with a Mitchell overdrive and probable 35 Ford Wheels. It was on the "Motor Trend Live Stage" where it was discussed and filmed it after the sale.
I got some blue reflective tape from a police officer. It is the same type of material as the red and silver reflective tape, only it is blue. I think it is about the correct color, and can be applied without brush marks or runs. The big plus is that it reflects light and is at least a small...
The stock generator quit, although it did possibly work intermittently. I tried 2 other stock generators. One worked intermittently and one did not work at all. All 3 generators will "run like a motor" on the bench . I don't think it is a cutout problem as each generator its own cut out. I am...
Hi,
I am thinking about having either a Zenith A or B carb rebuilt and internally air balanced. Does anyone have a recommendation on a repair shop that does this type of work?
Thanks,
Hi All,
Four knowledgeable car guys have listened to the motor since I last posted. Nobody is sure what the noise is, but the most thought it is something in either the timing gear or the oil pump /distributor drive rather than "pinging". The noise is very sensitive to the advance lever and...
We switched from a Model A clutch to a V-8 style clutch. I think the V-8 style clutch may push a little harder than the Model A clutch. Also, the new V-8 style clutch was produced "offshore" and failed in about 1000 miles and resulted in having to pull the motor to repair.
Hi H.L. Chauvin:
I do plan to try and get another set of ears to listen to the engine, hopefully soon.
The other half of "we" is a very good Model A mechanic, who did listen to the noise and at least so far thinks is pre ignition.
Hi Mitch:
I live in NW Minnesota, and I hear "Yah...
More feedback:
Another question: Are you using a stock Model A distributer? With original points? I have 2 stock distributors I use. One has Model A points and one has modern points. I don't see much difference in performance.
Not doing a failure analysis is a sure way to have a repeated...
I tried more suggestions, Here is more feedback:
If you try this simple test, it may answer your simple "pinging" questions. I did the simple test, and set the timing at TDC. I did later check it with the timing light to confirm it is set at TDC
You had problems with scored pistons with...
