naka liners na yung block? napa-overhaul na ba yan before?

you'll need a full overhaul kit, plus cylinder liners (4). cylinder head you can buy surplus sa mga surplusan.

yan ang problema sa 4d56 eh... they don't last as long as the 4m40s and the isuzu engines. within 10 years of ownership magpapaoverhaul ka talaga. i've read somewhere na may fault yung design ng piston and piston rings ng engine na yan, kaya madaling mag-blowby.

i would go for a quality engine rebuilder. mymitsu club recommends ray sarol, but i hve no contact number. maybe you can ask around mymitsu...

isabay mo na yung calibration para bago isalpak lahat at istart tama na yung fueling system nya. too much diesel and the fuel will wash down the liner bores preventing the rings from seating properly. pag kumayod na yung rings you'll be right back where you started.

Hindi naman problem 4d56, 16 years na L300 namin at ang problema

sa ibang spot naman ang kalawang. 120,000kms odo 1st hand din at naalala
