Good to know that shouldn't be like that I guess. I was contemplating cracking the cases again. If I have to get more pistons and another rebore then so be it. I'm this deep in.

I would start by taking it back to the machine shop that did the work. They did the work, they can measure everything up again and advise.

eight0:
Thanks for the advice Julie.

I'll go over there tomorrow. Seems odd that the ring gap is in spec and the pistons fall through without the rings bit it's still binding.

Let us know how you get on.

Nurse Julie:
Just one other thought, have you got the compression and scraper rings in the right way up 🤔

The writing is facing upwards. That's correct right?
