Thanks for the tips. How do you feel about a hone and rering using the existing cylinder liners??? I am just going out on a limb before teardown and thinking the rings are shot. I found an aftermarket controller I am going to "tinker with" to see if I can get the jatco to work without the factory ecu. I will cover all of this when the time is right in my vlog of course.
I appreciate your responses....
On a sidenote: Do you have a link to a master rebuild kit for these engines that you have used and recommend?? I see the ebay kits but I don't think they are genuine.
If the existing liners are good then I would absolutley hone and reuse them. For parts go straight to an Isuzu or GM truck dealer. There are some online Isuzu truck parts sellers. Do not shag around with any of the ebay kits. The liners and pistons are graded into kits with 4 sizes based on the bore size in the block. If the engine hasn't been monkeyed with then there should be markings on the block deck to say what grade was factory installed. If the engine has been rebuilt then they'll likely be gone but you can measure the bores to confirm.Also, when searching I keep seeing grade 1x or 3x liners. I am guessing that designates some sort of tolerance sizing??
Have a dig through my recent post history for Isuzu 4BD1T liner tolerance games. The 4BD2T uses different pistons but the same liners and rings.
