Mate, you have been ripped, raped, and robbed!!!!
I'm suprised you even still have the vehicle.
You were also lied to about the Isuzu pistons, you can't actually buy them in a set, you can only buy them individualy. Same with the rings and liners, and usually they are sold as a set. The piston, rings and liner. And they are pressed in crome liners, so they have obviously charged you for a boring job when you didnt need it.
Man I would have been swinging with that sort of service!
Not really. Most of it was simply ****ty aftermarket parts and a bad aircleaner. I have now learnt my lesson regarding aftermarket and genuine.
If you have a part number for individual pistons then I'd like to know, the aftermarket pistons currently in there are niggling at me.
There's no way the isuzu truck parts guy was lying to me and no reason for him to. If he could have supplied the pistons I would have bought them. But he could only supply matched piston/ring/liner sets.
The boring job was needed.
The previous owner had the block bored to fit thicker wall cast-iron liners. They had to be machined out to the original bore size to allow fitting of the new chrome liners.
I could have avoided the machinging by simply dropping in another set of cast-iron liners. But no way in hell.
Apart from the block machining I have done all the work myself, so it's only wasted time, not paying for someone else to screw me around.
Mate I hate to be the bearer of bad news but I think you might be in trouble with this engine.....
double lining does not work all that well and unless youve got stupidly tight liners or tophat the inners over the outers they are more than likely going to "squirm" in place which aint all that cool.
Find whoever installed the oversize cast iron sleves and kick them repetedly in the behind....
Id suggest that as a precation to installing your cromes inside the casts that you preheat the cast iron sleves to about 120ish degrees and the put the crome liners in the fridge. They'll still need pressing in but if you do it quickly with one of the screwjack type seaters you might get away with running the inner sleeve as an interference fit.

If you've benefited from one or more of my posts please remember, your taxes paid for my skill sets, I'm just trying to make sure you get your monies worth.
If you think you're in front on the deal, pay it forwards.
All Isuzu liners are "tophat" style, they can't slip down.
The engine has covered approx 40,000km since at up to 20psi boost, so the testing is well and truely over.
Many engine rebuilders use the cast liners for two reasons. The first is they're convinced the original bores aren't round, the second is cost.
Anyone mic'ed up their bores to see how round they are? I suspect they're mostly making up stories to justify reason #2.
