ISUZU 4DZ1 engine

Hello friends, a consultation to see if someone happened to someone. They brought me a luv which grabbed or grabbed the bolts on the pistons, the engine has a few kilometers ... I still don't find the reason for such a situation ... Any suggestion?

Hi Henry, you say you have few kmts ... how how many?; If they are very few, it gives to think if it is not a factory defect (which is surprised that Isuzu fails this ..) very tight tolerance of the bulon, problem in the material or temperate or machined of this piece, problem in the connecting rod or in its bearing/ enclasquillado, I mean that it is rare that it has happened to you in all the pistons and it will be bad to think that the connecting rod It was a lack of grease, the crankshaft, connecting rod, turbocharger, rocker axis, etc ... would have gone ... then that this engine has not been opened or repaired above and they have mounted badly ... I hope I have explained me. greetings!!

I do not understand how the bolts grabbed on the pistons? Do you talk about the bolt bolts?
