I have had the xpag engine resleeved back to standard, this has left a lip at the bottom , between the new sleeve and the old bore diameter, so small(.030") this has made it impossible to fit the new rings and piston with my ring compressor. As the lip is only .030" would any harm be done if I were to taper this part of the bore to match the old bore size . this then would allow the rings to go into the new bore size, ( the reason I had it resleeved is because the engine had been left out in the rain and damaged the bores beyond any over size rebore. hence back to standard) Or is there another way??

Install pistons and rods MINUS the rings from inside crankcase. Push pistons past top of block sufficiently to allow fitting of rings. Install ring compressor and then guide pistons back down into cylinders.
 
Thanks for the intelligent reply, Now why did I not think of that!!! So simple, I had all sorts of ingenious ideas, I even asked an MG dealer , no luck there. very impressed. Saltiga
 
You should be ok, but check the stroke of to piston before fitting the rings. I had the same issue and the lower ring would touch....better safe than sorry later.
 
I wouldn't hesitate to leave the lower skirt rings ( If the pistons use them) off if they are even close to the step. I've had to do that twice with no regrets.
