Be careful with oil additives. For example, Avblend is not recommended as it dissolves some of the sealants used between the case halves, etc. I don't know about Sea Foam Deep Creep.

Subject: compression
While doing my "Condition" inspection I found that #3 cylinder had dropped to 56
/ 80 on the differential compression gauge ( engine warm ). The other five were
72, 74, and 76 average. The leak is through the rings because I can hear it
in the Crankcase breather line to the catch can. The next day ( engine cold
) I put a pressure gauge on the cylinders and spun the engine with the starter.
All cylinders were up to 90 psi or above including the #3.
The engine is not using oil excessively ( about one to two ounces per hour ) and
the oil is clean - about the color of maple syrup after 25 hrs on it. I sprayed
all the cylinders with Sea Foam Deep Creep and am letting it sit until I
get back there to run it and check differential compression again.
Has anyone dealt with this problem or know how to fix. I plan on flying it for
a for an hour or two and try the differential compression test again.
Thanks for any input.

So, it was recommended to me to run the engine up in rpm fairly frequently to get the cylinders hot Enough to keep things clean. (Burning off carbon)
Just my 2 cents

Sounds like you are doing the correct things prior to the next check.
On your next flight I would recommend high power setting to help clean
potential dirty rings.
