G'day Wherehegon
I actually own a 80 Series 1htd intercooled 1992 Sahara wagon.
All factory everything plus two tons of personal add-ons.
They are quite a nice vehicle even by today's standards, my particular wagon has covered 310,000 kms.
It's original owner,( a friend of
mine) had dramas with the engine in it's early days at around 35000ks, sadly it was a major rebuild but at Toyota's warranty expense, apparently there was a problem with the early engine build crankshaft thrust bearings, I'm not 100% sure on this though. I suspect there was more to the initial failure.
I had a brand new 1htd (crate) motor fitted back in February 2007 the motor came directly from Toyota's warehouse in WA.
The reason for fitting the new motor was a persistent high engine running temperature with the original, even after checking and replacing what I thought was suspect, the problem turned out to be a hair line crack in the
bore of #5 cylinder and this one particular piston had non standard size piston rings fitted.
The transmission and other running gear is untouched.
I tow an off road trailer, when needed, I also tow a fairly weighty Coromal Off road (sic) caravan when getting away from home.
I've replaced all wheel bearings seals etc..., just this August, some may call this running gear, but I am not going to split hairs.
I've replaced all brake components, only because I wanted a personal start point for my own records.
My cruiser is used daily and mostly off road, and serious 4wding often, so it's service life is genuinely as Toyota designed it for.
In a nutshell, they are top a touring vehicle, when personalized and once you have confidence in it.
I would without hesitation buy another 80 Series Sahara if I could afford one.

Hi there Joe, thankyou very much for that info. I presume maybe the issue with your motor was what I read up about with the bearing issue ?? Not sure in what model the issue was rectified. I have read that it is worth replacing the bearings in the bottom of the engine every 100 thou and its not an expensive job to do so and give you peace of mind. Im just wondering where I would find out the info that would tell me what year models were affected by the bearing issue's. Thankyou WHG

Joe, as you say the big end bearings are a concern and were a continuing problem throughout the 1hdt range and even showed up on some 1hdft multi valves.
So long as the big end bearings are changed at about 100K intervals there appears to be very little else to go wrong, if they haven't been changed recently then use that as a bargaining position to try and reduce the price to cover the added expense.
Main crankshaft bearings never seemed to be a problem it was always the big end bearings that copped a flogging.
Regards Andrew.
