Using "Restore." Mechanic said to check first. So I'm checking.

Have been fortunate to work with a mechanic who has affordably brought the 77B to the point where we now have "good gas, good air, good spark" - everything but good compression. I've booked a rebuild with a highly recommended local machine shop (their work, particularly with vintage power plants, is museum quality) this summer. Until then, my mechanic suggested I give the motor a dose of "Restore" as a Band Aid of sorts. He said he's had some good, and some mixed, results with the stuff, but he cautioned he's never used it on a MG. "Probably okay, but check with the Internet folks," he suggested. And yes, the car (now) runs surprisingly well despite the lousy compression numbers.

So, "Internet folks," I'm checking. The product gets decent reviews. And, with a rebuild already on the horizon, I guess the only issue is what, if anything, to expect (like being stranded on the side of the road?) before I go out and blow $8.95. Insights?

Tried it once on an old Pinto. Fouled the plugs. It could have been way past done. I tried the experience stuff as mentioned in some threads here. Got maybe 5 Lbs out of it.

What are the compression readings? Was the test also performed after addition of a bit of oil to each cylinder? Results?

I've used it. Everyone I talked to about it said it worked for them, but I didn't notice much difference.

Similar test results were independently obtained by two mechanics. The tests were done correctly. The results aren't in dispute.

Well Gary, if you want an opinion you need to provide more than a question.

Just buy some and pour it in. Then you can be a person with personal experience and you can post yohr results here. We would love to know.

One test "wet," the other "dry." Numbers (gulp) ranged between 45 and 70 on both. Sorry, didn't mean to be chippy. Just wanted to focus the discussion on the use of "Restore." The engine is going into the shop, with or without it.

I think that you answered your own question.

Most probably what's gonna happen. Might not help, but it appears unlikely to hurt anything. Am also searching for that "Snake Oil" stuff. Appears to be popular.

How much oil? I guess if I use a small syringe I can squirt it around the walls.

Does it matter what kind of oil; 20-50, 3 in 1?

After many years of a push-on checker, finally found an inexpensive screw-in I haven't used yet.

Your compression numbers suggest that it is rings, not valves. That said, Restore or any other snake oil may provide slight improvement. AFAIK Restore is not nearly as viscous as something like 'motor honey' so taking up the gap between the rings and cylinder walls is less likely. Unless you add saw dust, additives are not going to cause any problem.

Restore will give you a quieter running engine. Don't be tempted to add too much, or more than instructions say.
