Dude, these vans are the ultimate machine.. I got a work van, (suzuki carry, holden Scurry) same thing, and the are the hardest thing to kill.. I just beat it every day, started it up, rev the shit out of it, drill it when it's cold, go through the gear box up and DOWN without using the clutch. And it just keeps going.. it's insane
done 350 000 since new, on it's 2 block and 3rd head.. when I got the thing, the head gasket was on it's way, boss told me to keep going till it died in the arse.. well.. when I drove around with the seat up and the radiator cap off, and jsut poored water in it every time I stopped I new it was time to get it fixed. That and you poored the water in the radiator and it came straight out the exhaust.
but yeah.. new headgasket and shes on her way again.. damn things are unable to die..
