Your truck wasn't a workhorse I don't think OP's truck is either.
Your motor would of lastest you 30 years or more having seen it was like when you sold it.
There's many Toyota's in our village the one before the Vigo that are neglected and some that get looked after and are like new.
Todays wheels if look after and kept will be a lot cheaper than changing motors if people want to do it, I will certainly not be changing my truck.
