This liner difference had us thinking!!!!!

Thanks, I’ll get that app sorted, your correct in saying there’s a multitude of issues. they all lead back to counterbores that are not square and without some out interventions we would have no choice other than being submissive to the manufacturers temporary repairs and inevitable failures, been there, paid for that!!!
I am a staunch advocate for everything that is preached on here, we don’t take shortcuts of have cowboys play with ECM’s.
What’s so disappointing Rawze is that when I measure any other older block we’ve got, every ledge is perfectly square.

Sorry, I should have cleared this up also, I knew it had dropped a liner before it even got back to the yard and I had a spare block sitting here that was at the machinist before the truck got back, I was going to save a few days doing it that way, it needed a clutch done too. please also remember that our pool of workers over here restricts how quickly a mobile machinist could do it, we were told 3 weeks.

I do want a cutting tool of course, Australia has sold out and only 1 company in the states will ship them here, about 8grand our money.
That’s not the problem, it’s more knowing who to trust so far away.
I’ll use the link you gave and try them. Thanks.
