30 lb very low to me, yes you can remove force pistons without cracking the case, pain in the rear but you can remove the bottom of the rod through the intake, then pull the piston out the head

Re: force 50hp rings

Your compression should be around 125 psi, hopefully you've just got blown head gasket if so it's an easy fix. just remove head and check cylinders for scoring if you got scratches or gouges you've probabily got some broken rings but hopefully not. If you got gouges you got more problems and work. Be sure to surface head before replacing the gasket, cheapest way is to get a piece of fine grit hard wood floor sand paper (the 2ft x2 1/2 ft. size at lowes) and stik it a piece of glass or other truly flat surface and rotate it (the head) in circles till all surfaces are shiney no dark spots. Its a little time consuming but works and lastly be sure to change the water pump the entire unit impeller, housing and cover plate, It's not that expensive and if you don't and it'll just overheat and blow the gasket again.
