light, gum solvent?

[Sweating in Florida]

In my Operations manual page 43 it recommends pouring 1/4 pint of a light gum solvent down the carb as the engine is running. This is supposed to quite noisy valves especially if you have found sludge in your oil pan. I remember we used to do the same on cars using ATF. It was also supposed to clean the engine. I don"t know that it did, but it did make huge clouds of smoke. So what is the modern equivalent of Gum Solvent? Could I buy it in the Home Depot paint department?

Just get some Marvel Mystery Oil. Remember, that same manual says use 30w non-detergent oil as well. It was written between 1939 & 1952.

Sludge in the oil pan is a by-product of low engine temps (as in "It doesn't need a t-stat") or years on non-detergent oil use.

Thanks Bruce
I was trying to think of the name MMO. I guess I could put half down the carb and half in the oil.
While waiting for hydraulic parts I changed the oil. Had to do it cold because the trans was drained. There was alot of sludge. I felt sorry for the old girl.It will take many oil changes. Cleaned what I could and oiled it back up. Checked for a thermostat and it was in there had a new one but the old was lodged in tight. It seems to run warm enough, but would love to have a temp guage. I remember when in High School that I use to buy reclaimed oil for my leaky car for 25 cents a quart. $3 a quart is the cheap store brand now. My we have come a long way. Thanks and take care.

That would have been my guess.


After looking over the web, apparently not.

[color=blue:11a009eedf]Gus managed to smother a grin- He looked at his young assistant and shrugged his shoulders. "Well," he said, better get back at them with a wire brush and make sure this time you get them thoroughly clean. It would be easier to soak them over- in a gum solvent-ethyl acetate or something like that-to loosen the deposits and then hose them off with an air jet but I promised Mr. Underdown I’d have his car ready this afternoon.

Stan went to work, and when he brought the manifolds to Gus an hour later the inner passages of both had been polished clean.

"O.K.," Gus approved after in inspection.

"That's the kind of job you should have done the first time. And here's something to remember. If you ever use a gum solvent to get the varnish binder off inside any intake manifold, be very careful to remove all the loosened matter afterwards. That stuff call cause real grief if it gets carried into an engine.[/color:11a009eedf]

Im thinking you are very close. Turpinetine was a common product on the shelf. So they would have called it that, but it is probably a close relative of turpintine.

After looking over a Google search, it would seem that they are talking something in the neighborhood of carb cleaner.

I don't know the answer to that, but it brought back memories. When I was a kid, I took somebody's suggestion for valve and combustion chamber cleaning and poured about a cup full of popcorn down the throat of the carb on my Mom's car.

It actually helped (or at least had no deleterious effects)! Of course, at the ripe old age of 16, we all were "mechanics with a good ear for engine tune". ;=)

I've thought about this a few times over the years and can only conclude it was a combination of gentle scrubbing action of the hulls and the moisture content turning to steam.

Someday I'll try is before tearing an engine apart.

TOH,

It would smell wonderful! Maybe a little butter on that?

Thinking back, I can't recall any popping sounds either. ;=)

I'm getting a chuckle out of just remembering it.
