It's a rotating part, so it's going to wear a *bit*. That's logical. I guess what I'm trying to say is that these shouldn't be wearing to the point where people feel the need to replace them. It shouldn't even be on the list of "things to do while I own my car". The wear, if clearanced properly, should be very, very minimal over the ownership of the car.

Agreed. BMW screwed up. But at this point it is what it is, and lots of us are choosing to take care of it with what is available.

Im not worried about the bearings in my S2000, unfortunately that wasn't the case with my M.

Don't worry, just drive.

Funny as I had a 9k rpm, 12.5:1 compression B18C/B16A hybrid in my del sol and I never once thought about the bearings. Kinda poking around for an S2K now....

Anyways, back on topic....

You could also take any of the color photos of these bad bearings and turn them into gray scale to see how they compare.

The ARP BE-specific rod bolts are shown as back ordered, but with an expected fulfillment date of 8/8/16, which has obviously passed. Anyone have an information on when these will be available?

Thanks!

The clevite examples are of an engine at time of rebuild which should exceed 200K miles, not an engine with 30K, 50K, or 60K miles. Anyhow a rod bearing should not exhibit much wear at all, since the hydrodynamic wedge of oil in the bearing is supposed to prevent metal on metal contact if the bearing is engineered and operating properly.

Most all of the bearing wear you see occurs on a cold start cycle, during operation very little contact of the bearing and journal ever occurs.

Here is a post I made in another thread with pictures of my S50B30 bearings with about 90K miles on them. I'd consider them normal wear for the mileage:

Hello All, thought I'd post a photo of some bearings that I thought would be relevant to the conversation here.

The background to how this came about is that I started getting an oil pressure light at idle on my 1994 E36 Sedan (S50B30 Euro engine). I changed the pressure switch but the light still stayed on so I got some fittings, a gauge and made up a hose at work and gauged the pressure. Once I had the gauge on the car it came clear what the issue was, the relief valve in the oil pump was stuck partially open and I had next to no oil pressure at idle (2-3 psi at idle even on a cold start) but lots of oil pressure as the revs built (over 100 psi and climbing by 5000 RPM).

Once I finished troubleshooting I ordered a modified oil pump from VAC with the upgraded keyed shaft to prevent the E36 oil pump nut and shaft shearing issues and proceeded to disassemble the car. Part ways through the disassembly I decided since I would probably never drop the subframe and oil pan on this car again I should do the rod bearings. I ordered bearings and bolts and waited for all the parts to show up.

Anyway, the engine is all back together and oil pressure is now within OEM specs so here are the bearings. The engine has 94,000 (151,000KM) original miles on the original bearings (date stamp of 04/94).

One interesting thing to note is that the clearance specs on TIS for the S50B30 are 0.001 - 0.003" (0.028 - 0.070mm) which would put the nominal clearance right at 0.002" (0.050mm). Redline is 7280 and oil weights come from a wide variety of grades in the Xw30 - Xw40. Based on the 50mm rod journal diameter the nominal clearance of 0.002" (0.050mm) would put this engine right at the 0.001"/ inch of journal diameter that many of us have been quoting as best practice for a while now.

Any how, back when BMW was building these engines rod bearings were not known as a big issue and strangely enough they were building engines with tolerances much more in line with what many of us would like to see and right in line with what the new BE bearings are giving us for clearance .

What did you use in the S50B30?
I know a lot of people change the rod bolts to ARP as the OEM ones can stretch.

I put OEM Bearings and rod bolts in the S50B30. I measured all OEM bolts that I removed and in fact none of them were elongated at all, even compared to my new OEM replacement bolts. So in all reality the bolts could have been reused.

I should note this a Euro S50B30.

Interesting. I wonder if the bolts stretching is an actual issue or another example of internet driven engine hypochondria.
Yep I'm interested in the euro motor as that's what we got in Australia.

I had to sell my BE bearings + bolts to a friend who bought a E92 in Europe. I also just got another E9X so I placed an order for two more sets of bearings + bolts.

How do we know which is the 'top/bottom' bearing or are they both identical? I looked at the ones I got previously and I do not distinguish a difference between the bearings

They are identical.

I can't speak for the S65 bolts, but on the S50B30 the bolts did not stretch after being torqued.

Do we know what happened here to the BE Bearings? Both of their Group Buy thread have been locked and are no longer active. Many of us ordered in July when they said they were in stock but it is now 2 full months later and all we have heard is silence. Not impressed with their total lack of communication.

I called autotalent and got my shipment sent out.

JonM · 10-04-2016, 06:39 AM

Other than the e-mail addresses listed on their website, how does one contact BE Bearings?

The website shows an 11/4 in-stock date. Are folks ordering now and waiting? Do they charge your card now or when they ship?

SYT_Shadow · 10-04-2016, 06:43 AM

I ordered two sets. I'm waiting. I do not recall a charge for this

SDPLV · 10-05-2016, 01:25 AM

Ordered mine about 2 weeks ago, right before they went on backorder again.
Received my BE Bearings quickly last week.
Was scheduled to have BE Bearings swap tomorrow.
OEM bolts have still not come in. (Wasn't interested in getting the ARP bolts.)
Sent two emails but no reply.
Will have to call up AutoTalent and report back.
