Re: Help me identify engine noise?
I promised to report what I learned:
Based on many inputs gleaned from other threads on this forum, I decided to also check out the rear motor mounts. The rubber between the rear motor support...

Re: Help me identify engine noise?
I have had a similar noise in my 1930 coupe for over a year. This noise would come and go, but mostly was at some high or low idle speeds and not others. I found that it would come and go if I moved...

Babbitt scraping . . .
Although I have done a lot of scraping cast iron ways, scraping the bores of babbitt bearings is totally new to me. I have three scrapers from the Model A days and have only used them a little --...

A simple question . . .
I just did some double-checking and, using a piece of ground tool steel round-stock, checked against my straight edge for straightness, I got the same "rock" with the center main being higher (engine...

Missing rod . . .
Bob,
I'll match the weights of the rods after all the machining, so do not worry about that. If you send me a light rod, I'll just take weight off the others, which are not very close now. The...

Bob is real . . .
Tom,
I do not see how Naval Jelly would have a short shelf life -- so long as the bottle is sealed. The modern version should change color if it lost its acidity.
Bob,
Glad to see you in...

De-rusting . . .
Tom,
Naval Jelly is just an expensive way to buy phosphoric acid -- it is jelled so it does not run off, so it is worth the extra cost for many uses. I cycle through brushing it on and "stirring"...

If you cannot find a plug, the fitting is (as Jim posted) for 1/8th inch tubing. It is a compression fitting which should be available at any good auto parts store and if you put a piece of...

I certainly would agree that any mild acid would help break down rust. Some folks use soda pop which is acidic (ask your Dentist). The patience to let it soak and work is another factor. When soaking...
