▀▄ eas | S65 Rod Bearing Replacement Inspection/Services

The only true fix I have seen for this is to have your crank turned, milled down just a tad. It just to tight stock, would you offer this service? Also can you torque plate down the engine/mill/polish block back to specs? Don't know why they don't do this when they build the engine but its what causes these cars to eat oil.

what about crank/main bearings?
are they prone to go bad too?
how difficult is to inspect them? need to pull the whole engine out?

No issues reported with main bearings that we're aware of. The block will need to be split to remove crank, it's easiest with engine removed.

Hi Tom,

How much would this service cost on an S85 motor? Considering on sending my car out there.

Info
Vehicle: 2008 BMW M3, 6MT
Production Date: 12/07
Oil Used: TWS Motorsport 10W-60, 7500mi intervals
Mileage: 62,833 mi
Fuel: 91 Oct
Driving Habits: Street driving, no track use
Oil Analysis: None provided

Notes:
M3 was just purchased on used market, came in with audible ticking. After getting oil analysis performed, it was quickly scheduled in for bearing service. Engine failure imminent if not attended to immediately.

Bearings were replaced with WPC Treated Bearing Set & ARP Rod Bolts. Engine and oil cooler/lines flushed to clean out any remaining debris.

Images:


As seen, bearing #2 suffered the most damage, with all remaining bearings showing considerable wear. Bearing particles were visible in oil filter element, required flushing to make sure all particles were removed from engine, lines and cooler.

Blackstone Oil Report:


Driver is very lucky to still be driving his M3. Schedule your appointment today!

Would be great if you could post work done on a track use car.

Appointments available, call or PM/email to schedule your service today.

Silly question, do you offer the VAC bearings as well? Or just the WPC?

Everyone! I'm not trying to start a flame war over what's better than the other?! Its just a preference thing.

Do u have any deal on the parts only
Since I'm a bit far from u...

How much for the labor if I bring the bearings, rod bolts, and my own oil, Tom?

If you have not been replied to, my apologizes, sometimes the forum does not email notifications on certain threads.

This will depend on OEM or ARP bolts, due to labor involved. Do keep in mind we have parts readily available in stock.

Purely up to the end user. We've had good results with both, most everyone asks for WPC treated bearings.

Any other questions, please call, email or PM directly for the quickest reply.

Just making sure no one got missed!

Great price. Debating on towing my car down from the Bay Area to have the work complete by Tom.

Is it safe to assume that none of this would be covered under a factory, CPO or extended warranty? I assume so since either failure needs to occur, or the owner is concerned and having it checked.

I'm picking up an '11 E90 on Monday and planning on having the oil analyzed shortly after to determine if I should have the rod bearings looked at.

Extended warranty will not likely cover any items that have not yet failed.

How much just for the parts?

Why is this oil report for a straight six attached here?

We have parts listed on our website, feel free to PM m3 if you are looking for anything specific.

Blackstone has done this in the past, typo on their part. There's 16 bearings (upper/lower) showing.

Hey Tom, I bought an e92 m3 2012 second hand and currently has 28k. Recently I've noticed a growing ticking noise separate from the ticking generated by the lifters. Its coming from the bottom left of the engine close to the drivers wheel well and the clicking is in unison with the rpm speed. Its not quite a developed rod knock noise but after doing some research I fear it may be a rod bearing issue. Now, I still have a year of original factory warranty but I still plan on getting the rod bearing upgrade from eas however had a few questions.

-since I’m under warranty, I plan on having my engine checked by the dealer. Can anyone suggest the best way to approach the dealer?

-if the rod bearings are indeed the issue, will the dealer swap out the bearings with the same OEM bearings potentially causing this to happen again?

-these issues were never fixed for the newer M3s? (my 2012)

Thanks in advance!

Get it inspected by your dealer and some sort of diagnosis in writing. You may need to pay for an hour or two of labor - but it may help if you have an issue later down the road if still covered by warranty.

Blackstone oil test beforehand is never a bad idea. We can always inspect if you would like, feel free to contact me directly if you have any questions.
