in the market for a hilux 98 to 2004 is there any motor that is a a grenade or are they all pretty good

3rz's can have a bit of valve seat recession, especially if they are on gas. 1kz's cracked the odd head. 5vz's had a habit of cutting chunks out of the radiator with their engine fan during river crossings.
None of the engines are bad, but did have a couple of small probs. Nothing like the Nissan ZD30's. Those things were fantastic
