I know this engines have a small cat converter just after the flex pipe, its not as a gas engine one, in fact it looks like a small resonator, I had to remove mine and now it pulls a lot better.

Let me put it this way: maybe you had a catalytic converter, but it wasn't factory. :) They were NEVER compatible with mechanically-controlled diesels. In fact, they're problematic even for today's computer-controlled diesels. They have various workarounds to solve the soot problem. Some use an "aftetburn" cycle to clean their cats.

If you paid someone to install or replace the catalytic converter, you should insist on a complete refund. Any mechanic should have known better.

I didn't know it was not factory, anyway where I fixed the exhaust they told me it was better to remove it and that's exactly what I did. Good to know that l, thanks for the info.

Everything was fine, I was so happy am proud of my truck until today, I started to get a shaky idle (again) I don't know what the cause might me, the only thing I can think about is due to weather, yesterday we started getting lower temperatures. Might she need the thermostat now? When it warms a little bit, it starts to run smoother but I don't know.

I'm just curious. How much did it cost to sleeve your block?

increase the idle speed a little at the injector pump. It's a bolt w/ 10mm head and 10mm lock nut right there close to to where the upper radiator hose bolts to the timing cover.

I did that but I feel like she's idling to high, probably will go back to previous idle setup.

I paid $150, machining the crank and sleeving the block.

That's no where near as bad as I thought it was going to be. My engine needs a rebuild(turns out I don't gotta sell my truck). I may go down that route...

It's definitely worth it, now she pulls a lot better, more than I expected, not to mention MPG (I'm getting 30mpg) I really love her!

So the bottom line for the rebuild was about $2,000 when it was all done and ready to put back in? That was with having a mechanic just assembling the short block for you or doing all the work?

The only thing my mechanic didn't was machining the crank and putting the sleeves in, beside that he did all the job. Painting the block, valve cover and internally cleaning and painting the radiator. Also with new hoses.

Looks awesome!
Great to hear you did the liners. Or they actually sleeves(bore block for a thinly designed cyl wall)?
I thought C223's had cylinder liners(and/or "sleeves")?
Sorry. Know more bout the 4fb1's as far as Isuzus go.

Either way, looks like ya did excellent work, and caught something going south. Amazing ya got so much service out of a previous owner neglected motor.
Glad it's in good hands.

I'm not sure about the liner and sleeves fact, probably a Isuzu expert on this forum could clarify that :shock: . Yeah I love my Isuzu so much! I expect to have it for at least 10 years.

Nope from the factory there are no sleeves. Maybe some factory rebuild kits came with them? But from the factory there were no sleeves
