Purchase engine at 330,000km - stuff required before use?

[cjc_td5]

I'm going to put an Isuzu J series engine in a series Forward Control project I've just started. Probably a 4JH1 from a 2005ish DMax/Rodeo.

One has come up locally with 330,000km on it. It can be heard running before purchase. What should I be budgeting for before I used it in my new build? Just take head off and inspect, check mains, rebore/rings?? Service the injector pump?

I realise it a bit of a "how long is a piece of string" type of question, but I'd appreciate some knowledge or advice....

Thanks.

compression test, flip it and reseal the crank, check and replace the shells check and replace the injectors new oil new filters

probably in the order of $700 in parts to do that.

IF the compresisons low do a leak down if its rings give it a rebuild. pobably $2k in parts.

but how much are you expecting to do with the 101? if you're not going to do 100K in 10 years with it you'd probably get away with the cheap option.

noooooooo.....

compression ignition......

compression the gauges can handle, combustion pressure not so much.

you can do cold/hot but thats easy to eyeball on the startup smoke.

If you put a teaspoon of oil in, it will ignite on the first crank.

I know what you ment, thats why I said

Thanks Dave. Not a 101, one of these. I [emoji106]https://uploads.tapatalk-cdn.com/20200427/cc262f1ce9f0f2e138c58c73fe18b0c2.jpg

Awesome! Do you know what year it is? Looks like a 109 FC 2A (long bonnet was the early models?)

I'm no expert, but if it's timing belt you would change that otherwise I wouldn't touch anything.
I've had a 4bd1t that was sitting for years and it's been fine without touching anything.

Electronic injector pump that's pretty modern for a 109FC! [thumbsupbig] (everything is modern for a 60's car lol! why not stick to analogue injection? I drove a rangie once with the 2.8, it was a bit gutless compared to the 3.9, but it did the job just fine.)

4JH1 has timing gears so no belts to deal with.

The intention is to retrofit the mechanical injector pump, injectors and timing case from a 4JB1. A straight bolt up conversion I understand. So will end up with a 3.0l intercooled TD.
