You are brave! I am not sure I would trust a “wholesale engine rebuilder” to rebuild such an obscure engine. I realize that this is a common engine, but how many of them actually get rebuild? Most of them go into Troopers, that sell for $1500-$3000. Ideally, you want to find a specialist in Isuzu engines, but do such people exist in US? Second best option is to find a VERY GOOD local machine shop, who will take time to learn how to do this right. Unfortunately, most experiences machinists rely on their prior experience (90% of which consists of rebuilding American V8s…) and do not look things up .

But do keep updating us!

What did the job ended up costing you? Not counting the follow up costs, those are fluky and can happen to anyone.
