Actually no your wrong, WPC bearing is a treated oem bearing not a coating. It actually has slightly more clearance than a OEM bearing due to the shotpeening process. This does not include the new higher clearance custom bearings, still say better off doing it right and actually solving the root problem.

Take a look at the WPC treated process and you will see, is reason I did not use a coated bearing due to less clearance.

You have been running Motul 5w40, correct?

You're right I got it mixed up with VAC (Calico). Either way the BE bearings should be a lot better since they were specifically designed to address the clearance issue. Time will tell if they got it right or if we are all destined to go stroker route. Good luck with whatever direction you choose to go.

Didn't take long for the generalizations to come out. Wrong conclusion. Get the complete facts first before making panic posts. He said

I used WPC treated stock bearings

Almost exactly 30,000 miles on these new bearings and the car already chewed them up to engine failure, orignal set I changed out at 31k and were worn to copper on several. So yea... not happy.

"Nightmare" !!!

I said several times on here that only time (future) will tell if replaced bearings would be better or not..
Well , here we have it ...I don't think this situation sounds positive !
After reading this I don't trust my S65 anymore... even not for one single minute anymore !
///M-BMW...WTF is wrong with our motors ???

Man..I'm so sorry about your luck .

There are facts enough on page 1 of this thread !
And that number is only 5-6 % of what happens worldwide !
Not even 20% of the Bimmerpost S65 owners post the bearing failure on here because they are thinking about the value of the car , and actually they are/were right..
Facts , panic posts ...What a joke .

I ran motul 5w40 for the last 10k. 6k of those miles were HWY miles, was a road trip to california and back

Any idea how the wpc process affects oil analysis? It hardens an already hard bearing (as compared to lead babbitt bearings) so do you think maybe a uoa is pointless with these?

Was always mindful of engine but especially after i went FI, never went over 3k untill oil was at operating temp, oil changes at 5k. Oil tests every oil change, which last test showed perfect results 3k ago.
Did everything right and still got bit.

Going to stay positive though, was going to do a stroker rebuild way in the future. Guess I just get to have it sooner now

Sorry for you bruh. Thanks for being open on issues.
Thanks bruh.

Damn. Sorry to hear that.
Any chance you can send an oil sample for that other oil analysis that Auto Talent sent off? Someone here had fuel dilution on their sample and that's all we've seen of that test they ran.

I use blackstone, isn't that what they use? I dont have any oil from the previous change that I tested. Everything came back great though, no fuel or antifreeze/foreign matter in oil very low metal counts plently of addatives etc. Said was perfect report

Sure thing man, if it can help someone else I got no problem with sharing. Will be intresting to see what the pictures look like.

There's a Polaris analysis that uses a Mass Spec to analyze the oil.

This one has a elevated fuel levels, as did a few M5's in the link above.

Your bearings were made from copper-lead? Horrible if so.

My orignal bearings that I replaced at 31k were copper lead, most of those were down to copper. The WPC treated bearings I put in as replacements where the newer bearings that are Alum, my last oil sample only had Alum at 2.

Hopefully will get some pics of the bearings soon to see which ones failed.

Cmon man. Don't give up yet! It's not over

[Properstyle]

why people feel 5w40 is enough for a motor that operates at a 210 oil temp when not on it is beyond me. Even nissan recommends 20w50 in their sports car during hotter times. and the oil temps aren't as high as ours. the only place 5/40 helps would be on start up. after that when the motor is now hot that oil is like water.

[pbonsalb]

Whether with 0W40 or 10W60, oil will be around 210 most of the time. Maybe it is 10 degrees hotter with the thinner oil or 10 degrees cooler with the thicker oil. Only on the track or during the kind of hardcore driving I have not experienced in my 2 years with 0W40 (following 3 years with 10W60) might the oil cooler not keep up.

[squartus]

Engine being torn down as we speak, sending block to VAC and having them work their magic. Hopefully block is viable and won't need to source one of those as well.
Will start a build thread once work out parts/build CR ratio etc. So far dealing with VAC has been nothing but a pleasure.

Will be running 5w40 on the new stroker engine.

Ouch, I haven't heard of too many failures with the new bearings, even supercharged, so this is a bit disappointing. Looking forward to seeing your new build thread.

I run 5w30 in my 370z...I think that's factory fill. I will say that during the summer, the m3 definitely seems happier on 5w50 than 0w40. Cooler too.

This really sucks. The said failure could be due to a lot of things. However this is not awe inspiring! Sorry to hear.
