Ok, I checked your comments on the 4BD1T reliability thread. I just checked with http://www.parts-supply.com/ and they have what seems to be good deal on what they call and engine overhaul kit. About $1,500 for pistons, rings liners, gaskets, bearings, seals, pretty much everything you need. I asked him if it was Isuzu or aftermarket and he said most of the parts are Isuzu in that kit becuase there aren't many aftermarkets for those engines. I asked him about the questionalble quality of the aftermarket parts and basically his answer was that it depends upon the manufacturer of the aftermarket parts, there are good and bad. I guess my question is, is this the place you got parts from? It would be nice to get everything in one package like that and be done with it. Also what about the head, again my engine has 208,000 miles on it, I guess I will rebuild it while it is off along with the oil and water pumps, I understand they are rebuildable? Anyone done this?

I'm in New Zealand, the aftermarket parts I used and had issues with were from the countries biggest seller of aftermarket engine parts.
If they're genuine Isuzu parts, then it'll be written all over the packaging. I get my Isuzu parts from the Isuzu dealerships.
To my knowledge every part of this engine is available aftermarket, you can even buy complete copies of the whole engine (infact the whole NPR truck) out of china if you have the contacts.
Here're the rough prices I paid or was quoted(in $NZ, $US was approx 2/3 that).
Full genuine gasket set $NZ300 incl steel headgasket
Aftermarket gaset set $NZ300 has fibre headgasket
4 cylinder rebuild kits (matched piston, ring, liner) $NZ1600
Genuine piston rings (4) $NZ200
Aftermarket pistons (4) $NZ300
Genuine Big End bearing shells (4 sets) $NZ32
Just to reinforce what I said in the 4BTswaps thread. These are the parts that I would never again stray from genuine on.
Piston/ring/liner kits.
Gasket sets.
Oil seals (included in the factory gasket set).
