Timing chain OEM BMW or OEM FORD

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.

I have a 2013 328i with the N20. At around 140k kms I had a couple separate mechanics bring up the timing chain unprompted and note that mine may be on its last legs. I can\u2019t say I noticed any major symptoms or signs, definitely no lights on the dashboard.\n\nI bit the bullet and paid $3500 CAD to get it done at one of the best shops around, during which they do the valve cover gasket and a bunch of other key maintenance items.\n\nThey showed me how loose the chain was and brittle the guide was, so it was a good call. I\u2019ve known I would eventually have to get this done.\n\nCar is running mint since then.

Oil is cheaper than a new timing chain.

You have the N47 engine, which is known for premature failure and excessive wear of the timing chain. However, it's generally cars prior to 2011 that have this issue, with later iterations safer.

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.
