I don't think they make them. Back in the fox body days, the OE lifters in the 302 HO were made by Federal Mogul and the pistons by TRW; the production of these parts have always been from 3rd parties. I strongly suspect that there's a common thread here, given that all three US OEM's are affected, that traces back to supplier(s) COO and shady QC.
Of course, I'm not knocking the actual engineers doing the work, but the company that chose cheap manufacturing and design.
Torque converters also I think fall in this catagory
The engines were extremely reliable, particularly the fuelie ones, the rest of the car? Eh... lolSo the inescapable conclusion to all this discussion is that cars were more reliable, generally speaking, in the 90s
I would argue that in the 90s, there was less to go wrong, and things were made better. To include design with future repair in mind, in some instances. You still see 90s Chevys all over the place, out of a rust zone, I venture to say, we will not be seeing many 2020 trucks in 2050.
Maybe engines in the 90s were built better and it is hard to disprove that they were not, however engines of the 90s specced 10w-30 and 5w-30 mostly with 3K OCIs, could this have made a difference as well? There certainly is a correlation signal there.
I agree with exception to the later LS (4.3, 5.3, 6.0), but as many on here would remind, correlation is not causation. Which is true, but is an indicator of an issue.
12 years and 200,000 miles, needing a major repair, be it a frame, transmission or engine, if it's a base model stripper that isn't worth much, for a company, just send it down the road and replace with new. The one F-150 we still have has needed the entire A/C system replaced, which I'm sure wasn't cheap. Doesn't excuse FCA (or GM for that matter) for knowingly using crap lifters, but the sludger/oil drinker Toyota's didn't stop people from buying Toyota, nor have the Theta II's stopped people from buying Hyundai, and I assume the Tundra sales won't vanish just because their new twin turbo V6 is eating itself at an alarming rate. At least these all went 200,000 miles before a major issue.I too like to hit my head against the wall hoping it won’t hurt next time.
I agree with you here. This failure at that mileage isn’t shoddy in the fleet world. Plan replacements at 130k and avoid the costs.
Correct, GM and Stellantis/FCA have had the same problem for ages. Stellantis supposedly fixed it in 2018 with updated lifters with larger needles in the roller. When Ford introduced the 7.3L, they also had the same problem.
Yeah, problem seemed to start after the added VCT, IIRC, they changed the lifters at that time.
