Sounds pretty funny to me have had three 3.0l motors to date now and not a single one had any issues.
Mind you i never had any of em for more than three years (i tended to get board and sold em off for bigger and better) but this current ones here for the long haul.
My one ranger was a 1996 4x4 ex cab 3.0L auto. Truck had 285,000kms (about 180,000miles) on it when i sold it and other than some small repairs to the front end and the 4x4 it was mostly trouble free. the only job done to that motor was a Idle Air Control Motor and reg maintence. It ran on dino 5W30 oil and had the crap beat out of it daily. It hauled the most weight of any of my vehicals and did so struggling for every km LOL 3.0L DONT LIKE 4500LBS behind em LOL.
But still that truck NEVER left me stranded, went every were my brothers jeep could (and some places it did not), and even the POS a4ld trans never gave up (although it was on its last legs LO).
I still wish i never sold that truck i love my current ranger but they did not offer the 4x4 with the 3.0L anymore so i got a 2wd as i WILL NEVER own another SOHC 4.0L motor after my old mans exploder that lived up to its name with only 200,000kms (124,000miles) on the clock of JUST commuting duty.
Heres a pic of my old 1996 good i miss that truck on day i get another one.
The front plate and license plate damage was fromt a who could make it up higher on the snow bank competition i had with my bros jeep i won LOL he did not want to hit it as hard as me LOL
