Got piston out a few minutes,second and third ring were stuck in grove,,these are four ring pistons ..top ring was loose ,,,
I was very careful when installing rings. so sure there on correct,
I had to put one new piston in,can’t remember !this might have been the new one,
Now
to get it out with out breaking,then use grove cleaning tool to see what’s going on
Will let you know how it goes!!!
