Ok yes that's what I'm reading and seeing online

Have you checked the bearings yet? My guess is you only had one bad rod bearing that caused it to fail, sometimes the individual oil pumps fail and it didn't get lubricated? That's what happen to my friends 08 Jerez black e92 with 60k miles. Fortunetly his cam shaft wasn't damaged. Paid $3800 instead of paying 10k plus ya know.

Yea two rods damaged 7 and 8 oil pump failure

It is so freaking stupid! I'm so sorry that this happened to you! Did you have warranty? Talk to BMW and tell them off.

Which bearings would you recommend for upgrade

The two big choices are BE Bearings and VAC bearings currently trending... Both are good choices, but then again most of us are still waiting on some good long-term performance data to come back from people's cars who have switched to these bearings... Either choice is better than what you have in your car currently...

Really? He lives in Jamaica.



Seriously, I'd go with a used motor. You should be able to recoup most of the cost by parting out your old one.

On my S54...I made $500 more parting out mine with a blown out block that I paid for a used motor. Not a money maker...definitely a PIA but not the end of the world either.

That's the plan

Well Engine Bought and on its way. Thanks to this post was able to find an engine here on this site and just patiently waiting now

You're kidding. It's an air pump. I can think of a dozen shops off the top of my head I would trust. Don't think because it's a bmw people can't rebuild it. Unbelievable.

Why not make a thread with reputable BMW engine rebuilders that you trust based on personal experience and share with the community then? Help would be much more appreciated than random snarky remarks.

My point was that so often on this forum everything revolves around how BMW is different from all other cars. It's not. Coming from a world where engines are rebuilt, some special shop doesn't have to do the work, just a competent one. In my experience, just because a shop specializes in something doesn't mean they are good, it usually means they charge too much. It takes a machine shop that has a competent machinist and assembly guy, a rod hone, seat and guide machine, cylinder hone, line hone, flow bench, surfacer, a couple dial bore gages, and dial indicators.
It's not rocket science. I'll use snarky comments all I like, on a forum or to your face. Do some research. There are plenty of reputable engine shops in every major city.
If you're worried call people like Dinan, turner, vac. I'm sure they'll sort you out.

You certainly got a lot out of my short statement. I can't imagine how you interpreted my statement to say shops that specialize in bmw's are the best option to go to.

While it isn't rocket science, finding a machine shop to properly bore an alusile block isn't easy. Finding an engine builder to properly time an s65 engine isn't easy either.

Would you rather go to an engine builder that has experience with your motor? Or one that's going to be reading the manual and trusting that they get it right.

Neither of those are a huge deal. Honing alusil lined cylinders is tricky because the coating isn't terribly thick. Can be easy to blow through it. However, using a 400 grit diamond stone will clean then up pretty fast, probably in 5 or 10 thousandths. Using a .5mm oversize piston isn't an issue. There is a fixture, commercially available to time the cams. Each cylinder head is done independently. Not trying to be a dick, but like I said, if someone is shelling out 15k for a proper build the shop will know what they're doing.
