If you do not have a leak down tester, next best thing to try, remove spark plugs, spray a bunch of carb cleaner down each spark plug to wash the cylinder walls, drain the oil and refill with cheap but fresh oil, spin the motor over by hand a few times to help prime the oil pump, and do a compression test. Have a battery charger that can do at least 10 amps hooked up. Get the battery fully charged up.

Spin the engine over for 5-10 seconds no plugs, let sit for a minute. Then start testing compression, with a 5 minute breather each cylinder. Note your numbers.

Then pour 1-3 ounces of oil down each plug. Find a way to measure it. Laundry soap cap, make a line, etc... Test compression as soon as possible after the oil goes in. Still give each cylinder 5 minutes to cool down a bit.

Your numbers should be higher if rings are part of the issue. Cleaning the walls prior to doing this removes chance of sticky rings, though will not solve truly gummed up rings.

The oil will cover the gap, and also help account for too large of a piston to wall clearance.
No matter what, the oil ed up compression test will result in higher numbers.


But if you get something like 30psi higher, might be worth yanking the engine apart and checking tolerances again.
