It should fill the balloon up like this image. Doesn't take long to fill up so be ready to kill the engine. I don't know about a hot engine and a balloon,lol

The balloon I used filled up similar to that, maybe slightly larger initially. I left the balloon on for a good 5 minutes. When it started smoking, the balloon seemed to grow even more. Almost like a completely filled balloon, maybe twice the size of the balloon in the picture. Are you still thinking blowby at the rings?

Yeah, either rings, possible damage to piston skirt or damage to existing head gasket. It didn't take long for balloon to fill up, I stopped it to keep it from bursting. Obviously your breather is functioning properly.

Well sounds like time to pull the engine. I guess I'll need rings and sump gasket but I'll wait to order anything until I take a look inside. I"lol keep you posted.

Hello again. Sorry for delay in response. I finally got around to pulling the engine. I ended up replacing the rings and while I was in there the camshaft too. I put it all back together, adjusted the valves and it now runs like a champ just in time for spring. In the end not exactly sure what the problem was but I'd guess the rings. I didn't measure end gaps on rings before I pulled them so not 100% certain.
Thank you all for your responses and interest in my problem. Happy ending.
