well so far have done some research and it seems this little toyota p/u's diesel has a timing belt, and a light that goes off in the
dash to let you know at 100k miles it is time to change it.
well after 23 years, and 86k miles i figure to replace it before i drive it much, my luck and all
i will replace the w/pump with its loose brgs at the same time, along with the idler and tensioner.
replaced a cracked air intake pipe from aircleaner to intake, wow, that might have been a problem for this little guy if the
previous owner had driven it much in a dusty environment.
also found a site/forum on toyo diesel's and found out the following
the 81 to 83 model 2.2L L-engine is reputed to get the best mileage of the toyo diesels,
it also has cylinder liners, which should mean a pretty well designed long life engine.
what little i have driven it, i love it. at 2600# it is like a gokart with a p/u bed,,, too cool
