Hi
Have searched and found some info on the subject, but are the problems with big end bearings only on early 80 series with 1HD-T, 90/91 or??
Reason I ask is that I have been looking at( and maybe buying) a 95 model 80 1HD-T with 230` on the clock. Oil pressure is normal, does it been that bearings are okay??
Any thing else to look out for, never bought a car with 200+ on the clock

IMO its a good idea no matter what one you get to do them every 100,000 along with the timing belt and tensioner.
Early 80`s were recalled to rectify the bearing problem along with about 5 other recalls on them...One would assume seeing as a recall is free everything should be rectified.
But my original statement stands.

I just replaced the bearings in my 1994 1HDT with 260,000kms on the clock. They had already been replaced at some stage by the looks of it as they were not Toyota bearings that came out. I replaced them because I could hear a faint "clatter" sound when towing my caravan back from Inskip recently and sure enough, one was split in two and another had started to "relocate" the metal.
I thought the later ones didn't have the problems the earlier ones had bu it's good advice to definately do them every 100,000 kms. They are a very torquey motor and they are hard on the bearings. It is not an expensive job (bearing cost less than $50 from Repco, gasket goo and oil) and only takes a couple of hours to do. The risk of not doing it is too great IMHO as a friend of mine found out recently when his exploded bigtime.

mate has done his 3 times and they all come out pitted...the rods go egg shape and thats one of the causes of this...the 95 will have a 1hdft multivalve and it will not need the bearings

Were the early 95's multivalves as well? I had a feeling they were 1HDT's for a couple of months before going to 1HDFT's? Could be wrong though.
