Adding oil to cylinder.

[GSX93DSM]

Is adding oil to a cylinder,a good way to check for bad rings? The head is off the car. I thought by adding some oil to each cylinder and check it in a day or so to see if the oil goes past the rings. Compression test come back low numbers and a wet test really didn't help much. The block has no ring groove and cylinder walls looks good. I just would like to make sure before tearing apart block if I don"t have to. The head gasket looked ok, but I may look at it better. It's a cometic if it makes a difference.

Not the most accurate way, but can give you an idea

Yea, thanks I've done the compression test and leakdown test,bu tI want to make sure. Never hurts for extra security... Should there be a little bit that goes by?If so how much is too much?

Since the head is off, pull the cams out and fluid test it. this will check the valve seal.

Sounds good. Gonna try the block method first, and see if a lot of oil goes past rings.

I tried the oil thing. 1-3 cylinder lost 1/8 of oil and 4th cylinder lost 1/2 of oil in 50 hours. It has been cold outside, but I think I might have a headgasket or head problem. The compression test showed that 1 and 4 cylinder was off by 5 psi yet cylinder 4 leaked more oil. Any ideas?????
