I have quite a few of the 22 cid. power head motors, and I have yet to have one where the case halves were leaking. I have found crank seals, transfer port covers, fuel pumps, even a very loose reed block retainer bolt that can cause a crank case leak. What lead you to believe you have a case leak? These are real easy to separate the cases, so opening it up would not be much of an issue. A good time to replace the bottom crank seals anyway. As Dave said, this compression is good. Another item to check is the exhaust baffle cover to make sure it has not dried out and is leaking. Exhaust can leak into the water, and water can get into the block if they are leaking. I had a salt water motor that the baffle plate corroded through. These are great motors, and I am sure you will really like it once you get the bugs worked out.
