Wrong, all plugs should be removed, because if the head gasket is blown between 2 cylinders you won't know if all the plugs are in.

All plugs should be out. Makes no difference on the compression of the cylinder you’re testing but makes the engine much easier to turn over

You should consider a leak down test. This tells you whether the valves are seating correctly. If they’re not, this could cause low compression as well. These tests are usually done at the same time.

@nathanw5747 Жыл бұрын
Looks like you had a sticky ring or two, which is why the penetrating oil works to free it up and get you a better compression.. it's not a miracle cure, but it's enough to get the engine running which is what it needs to do they get the compression rings to seat properly again.... And I noticed that you got good spark there judging by the way you jumped LOL

If you do the same test with engine oil, I'm sure you would get the same result. Sea Foam surely covers the cylinder surface and the ring, and now they seal better like they would do with any lubricant.The second test should be done after using the running the engine for some time to warm up and burn the lubricant.

Sea Foam is not a bad product at all and surely holds its own against any other of its class (Power Tune, Marvel Mystery Oil, STP etc.) but honestly, its virtues remain short of magical as some users profess.
