Reviews of OEM FORD timing chain

Engine grenaded. Timing chain issue.

Seen a few comments about the 1.0 ecoboost wet belts. The post 2018 focus/fiesta moved to a timing chain on some cars (the only way to conclusively check this is by looking under the bonet)

I had something similar just done. Started with leaking gaskets so I went on ahead and got the timing chain, cam phasers, water pump...all changed out.

The 4.0 SOHC timing chain is basically a deathnail to these because it's such a big labor intensive "engine-out" job. That and rust. The rocker panels under the plastic trim, etc. If the 5R55E transmission had problems, it was usually just a valve body problem, and you can buy a rebuilt upgraded valve body for $200. So it was an easy fix. Also a lot of body parts for these have become unobtanium. If you need a fender you'll need to find one at a salvage yard. Mechanically most of the parts were the same as a Ranger, so plenty of parts availability there.

My 4.0 V6 Mustang has not jumped timing and destroyed the engine despite the 4.0 being infamous for it at very low mileage. It's probably because I actually take care of my car and change the oil regularly.

1976 Ford Custom 500, 400 ci, timing chain lifted off the sprockets, 3 cam lobes were rounded. Oil was regularly changed.

About 145k timing chain started slapping

I ended up spending 800 on genuine ford parts and did pulled the motor myself and took it as a challenge. Took me a month because I had to reorder parts and I was working a lot. The job is very hard and complicated and I have been working on cars for a good while. The good news is it runs like a champ now and it’s got 250k miles and I’m gana milk this truck for all it’s worth lol.

Ford equivalents use double link chains for the timing system. They last much longer than Mazdaspeed timing chains and are quieter. Reliability wise, they are solid. People use them all the time for speeds and beat the hell out of them.

on the Ford 4.6 around 175k you need to do an engine out service to fix timing chains because a nimrod at Ford put them against the damn fire wall.
