Maxwell coffee can lids work awesome for an isx bore. I couldn’t believe the price of a catch lid kit from Monaco tools. Nice work on the cut. I agree with you on a higher liner height I also herd 15 thousands on an isx is working fine.
Found Cummins to be absolute junk most require full inframe rebuilds between 240 to 300,000 miles. Your doing well to get more out of them. We have switched to Volvo and getting around 750,000 miles before any heads need to come off
