Obviously for a timing chain the engine would have to be pulled or transmission dropped. I think a full timing chain replacement is somewhat unlikely, though who knows as there are not a ton of high mileage engines to glean data from at this point. The far more common concern is repairing or servicing the VANOS system which is what controls the variable valve timing and will require special tools to complete. From what I have gleaned from the BMW community, expect a VANOS expedition in the 100-120k mile range and it can be done without pulling the engine. It's not cheap, and is complicated by the fact that the VANOS components will be located under the cowl, which is certainly disappointing, but not necessarily a deal breaker for me anyway.

Do I wish it had a simple naturally aspirated motor produced by someone other than BMW? Of course. I also wish I were better looking and more charismatic, but I deal with what reality gives me.
It's 100% likely unless you wanna push services intervals or expect to get rid of it sooner rather than later - I haven't seen any official documentation, but most timing chains are ~90-100k miles so on par with the Vanos if that data is correct, which is a full engine drop in a shop + $XXXX, never mind any mech issues in the field.

I'm VERY interested to see the technical manuals, BMW builds motors for multiple international markets often with quite varying specs. It's very possible that ineos could have requested a more robust international variant for this vehicle, but I will believe it when I see it. If not VANOS can be locked out and turned off within the ECU though emissions compliance could be tricky in some jurisdictions.


Historically timing chains on the BMW V8s need service more frequently than the smaller BMW motors mainly due to failures of the chain guides. I've currently got 2 of the inline 6's that are over 200k miles without having to touch the chains on them VANOS locked out on one, rebuilt on the second at 150k miles. Oil service on all BMW motors is key to long engine life in my experience.

AND many shops that are still Bosch service centers are unethical and provide horrific service to the customer, offer poor workmanship, and couldn't diagnose their way out of a wet paper bag. Of course the same holds true for many BMW dealerships, so YMMV.

The unfortunate situation with the service in US (and many other developed countries).
The older generation that had at least some work ethic acquired during the glory days of the American manufacturing industry is already retiring or some even have already left the workforce.

The idea that customer is always right, however ruthless it sounds, it’s pretty much out from the culture. Now they feel they are doing your favor.
I once went to a local Firestone… boy it was a sh1thole, run by illiterate baboons.

On top of this extremely complex and overtly complicated modern technology. John Deer is being sued by framers because they can’t fix anything in the new tractors.

Like many, I put the money down to be in line, but I really doubt I’m going to to purchase anything with a BMW engine. I can’t even begin to express how unappealing the thought of that engine/tranny combo is to me. A light duty truck drivetrain from any other manufacturer would have been a vanilla choice, and perfect for the job. I just wonder who sits down to design a defender replacement, that fixes the defender reliability flaws, and picks what is essentially a car drivetrain. Weird.

Comically one of the most desirable defenders has a BMW 6 cylinder


and the Rover v8 was used in, uh... Everything.


The chevy 250 straight six was in everything from bread trucks and pickups to camaro's and chevelles.

The myth of "car engine vs truck engine" is nonsense.

In most, but not all instances, I'd agree with that. I would put forth the Ford 240/300 sixes were always designed as, and run as truck engines - they never made it into cars. The same could be said of the light duty diesel engines (Ford 6.9/7.3, GM 6.2/6.5 and Dodge 5.9 Cummins).

Telling me something is more desirable than a rover v8, isn't the same as telling me something is good.

if were gonna go all classic, keep in mind, the recipie for american pony cars was to take out the typical passenger car drivetrains, and replaced them with the high torque truck v8's, transmissions, and rear ends.

Bide your time, a LS swap kit will be coming out shortly I am sure lol.

Yep, 4.8l GM V8 with a 4l60e and call er good. Haha.

As far as engine pull to do timing chain, plenty of Ford's get cab lifts or engine drops for major repairs on the 3.5 EB. I don't know what the Rams or GMs are like for major engine break downs. Weren't Hemis dropping valves?
Can't get the amazing HP and Torque in a broad power band without huge displacement or VVT systems anyways.

Hemis like to eat cams, radiator support removes to allow beautiful access. Not super super common but not unheard of.

Had a newer Cummins get a timing cover gasket a couple weeks ago, cab pull.

They've made a deal with Bosch to have dealers, parts, service and warranty all over the world.

My take is they probably have one of the most global parts/service network after the 70 series LC and old Defender.

They're also doing really cool stuff like officially allowing you to do your own oil changes and maintenance while still maintaining the warranty.

You mean I can do my own oil change and maintain the warranty?…

And yet a Corvette that came with a 350 is worthless at auction with a pickup 350. You might be correct on the 250 CHEVY straight six..... but that was for a price point, not performance. On a budget a manufacturer will use whatever is in over supply in anything they want to move. In a heavy truck vs a sports car there is no myth, the engine internals are different even if the block castings start out the same.

The best route for engine replacement under warranty is dealer records. The dealer can tell the warranty center "we changed the oil and air filters at this many miles and on this date" and it is all cut and dry.

The farther you get away from that the harder it is to prove anything. Come in with a box of parts store receipts and the dealer has no clue when exactly the oil was changed or at what miles or if it was all just returned a half hour later.

Most independent shops will will keep records and the dealer will generally accept them. If you are going to have an independent shop change oil on something with a warranty confirm they keep records and are using the correct oil/filters OR better yet provide your own and make sure they note it on the ticket.

I always change my own oil. Heck I built my truck myself. Dealer is changing the oil in the Bronco until it is out of warranty tho.

Once you get past "numbers matching" thing there isn't really drastic differences between them mechanically. Cam, intake/carb and exhaust will change a lot on their own before you even think about playing with compression/heads.

Not like they are going to have super exotic stuff in a 1978 Corvette engine.

Basically just playing with intake/exhaust and cam/lifters got the Mustang 5.0 40hp over a F-150 5.0 (and 75hp over a Crown Vic 5.0 which unlike the truck also had a roller cam)... but the truck had a better intake that wouldn't fit under a car hood.
