There is no way I'll be allowed to pull the liners without justification. Liner projection will have to be bad. There was no antifreeze in the coolant so that won't fly without a reason. Seems impossible to clean these without getting crap in places it doesn't belong with liners still in. I'll be cleaning and measuring tonight.

I wish you the best of luck Sir. I speak from the school of hard knocks. Mean nothing against your thanking.
Personally would not do what you are talking about unless it was going straight to an auction. I would still want to at least put rings in it and hone the cylinders. Some block sealer junk can be dumped in it to get by the o rings for a while.
If you have a pin hole in a liner you will be right back in it.spsauerland and Kenllah Thank this. -

His options are complete rebuild , which i would do instead of buying todays junk engines. At the very least a rebuilt cat is 100 times better than todays disposable junk. I tried just doing head gaskets on my cat before the complete platinum kit and the gasket didnt last a week. Save yourself the time and money and do a complete rebuild and run it for another million km. I just swapped out a dd15 for my 05 C15 . I cant afford to keep that crap running and i wanted my power back. Anyone who says a DD15 or 16 will run with a C15 CAT is full of it . They just plain wont
dirthaller and Smellfunny Thank this. -
Best I could come up with -
If its never been overhauled and has decent mileage which assuming a 20 year old 6nz does almost guarantee the liners have sunk. I'd probably measure with a new spacer plate
Kenllah and BoxCarKidd Thank this. -
There's a small plate on the passenger side of the block that has 4 bolts you can remove and see into the water jacket and see a liner or two. We'll can't see much but I would look anyway
Kenllah and BoxCarKidd Thank this. -
Hard to see for sure but looks like good cross hatch in the liners I can see, no odd wear patterns?
Kenllah Thanks this. -

Well, hell. The results are in...
We are out on #1 surprisingly. Something is going on with that liner flange. The closer you get to the liner the lower the dial is but out where the fire ring crushes, it's higher. #4 checked good but at the bridge between 4 & 5 it's suspiciously low. I don't have a proper gauge to measure that with the bolts in but I bet it's bad at that point
