It’s great you guys provide these videos for the community. However the process shown here to clearance the Vanos pump back lash is incorrect. The dial indicator style and gauge set up is inadequate for this application. You need a lever type indicator. If you want to wing it with a plunger style that you’ve shown here you really should be coming at the gear teeth on an angle to get a decent reading of the gear lash. Setting up a plunger type indicator perpendicular to the gear (the method shown here) is wildly inaccurate. Couple that with the extremely tight tolerance bmw specs for this application and you asking for an issue down the road. We do a lot of these jobs and have seen many s85s come through the shop with noise and gear wear on the vanos pump drive system due to incorrect setup. Usually from a bearing job. This is tedious and complex work. A good shop will have invested in the proper knowledge and tooling to do this properly and it’s worth the cost of admission if being done properly. Cheers
Hello sir! Do you by any chance have instagram or any other way for me to contact you? Im looking into buying a V10 M6 and I would love to chat a bit with someone who has expert knowledge!
I wish I a garage and a lift to be able to do jobs like this. This was awesome watching you do this and being very detailed about it, too. Thanks. I can't imagine what the book time is and what the BMW dealership would charge for this.
After hours of labor the final boss goes down and you just sit there staring at it. But wait, what? No credits and the boss music comes back even louder than before. Rod bearing job's bigger brother steps in the ring. OMG it's the complete engine rebuild!
Overall good information. One minor nitpick; the alignment tang on a bearing shell is that and only that - an alignment tang for ease of assembly. It has nothing to do with retaining the bearing while in use or keeping it from spinning. Each bearing half has slightly more than 180 degrees of arc length when installed in the cap or rod. The act of tightening the rod bolts "crushes" the bearings together and essentially makes them a press-fit in the big end bore of the rod. This interference fit is what keeps the bearing from spinning in normal operation.
Kudos to Gareth for tackling this project. What a nightmare of a job and total engineering failure on BMW. At least the current crop of BMW V8 S-engines don't have this issue. They just burn oil and leak coolant (ROFL). On an aside I need to stop watching these videos because it just depresses me that I can't DIY on my own BMW because I don't have a lift. It truly makes ones life so much easier.
Im getting confused , BMW oem bearings come with 3 different colors how I know which code should I get , do I need to measure the crankshaft first before ordering or what ?
I liked to you guys using premium hand too,s on a premium fine German automobile. Next time will you be able to switch to premium precision tools like a Starrett or mititoyo dial indicator , magnetic base, and electronic slide calipers? 😀
@@javarithms such things usually come from people who only owned corollas and civics and now expect cars with more power to run perfectly while they completely ignore the maintenance on them
The more of these videos that post, the more tow truck companies stay in business and the more jobs we will turn down. Because once it’s apart we won’t touch it. What happens to CarFax and service records? You have none. Amateur rod bearing replacement on an S85. The person that thought this was a good idea to post is an absolute idiot. You are placing consumers in a really bad situation when something goes wrong. If you can’t afford to pay a shop 15-25 hours for this job you shouldn’t be driving a BMW with an S85.
What if you want to do it exactly the way you want it? especially if you got the tools space/lift and time? IDGAF about carfax and service records ill keep my M6 forever and I don't trust shops to work on an S85 unless done by someone who ONLY works on these engine like Troy Jeup.
@@e.e9331 absolute ZERO ‘DIY’ consumers for us. We are a ‘DIFY’ business. But the lack of knowledge on engine repair in general is growing. An S85 isn’t a big deal really. Take apart a gear driven Ferrari V12 and I’ll start paying attention.
