*poringdrops: you have to inform your folks that the diesel engine of the old tamaraw is a shitty 2C which is notorious for heavy maintenance past 60T km of use, simply because it doesn't have enough metal in it . . . . during severe overheating - the engine block cracks, the cylinder head easily gets warped, etc. Users even brand it as a disposable engine - change after every 150T km of use.

Toyota learned from it's shortcomings so after the 2C, toyota introduced the 2L (2.4 li.) found in the Revo. Now that's a tough reliable engine. My cousin with his old 2L hilux ran it dry twice already (once from a radiator leak*180T km of use, the other from a water pump leak after 200T km of use), and it ran even without water until the thermostat in the water pump shut down the ignition to prevent further damage to the engine (he had a busted temp guage and never had it fixed). No cracks, no warp, engine still intact after running dry & severe overheating.

Even though the new D4Ds were just introduced late last year and have no reliability records to speak of, I'm sure they are light years more advanced and made tougher than those oldies. Basically no point of comparison - it's like heaven and hell.
