Rod Bearing Issue - What to do with the M3?

Add another S65 kicking the bucket due to BMWís glaring rod bearing issue Ė I guess Iím considered lucky as the engine started knocking at 135K miles (it has not detonated). However, I sure donít feel fortunate: I recently lost my job and not more than a week later, the M3 goes down Ė I hit a rough patch but I know tough times donít last.

Anyways, Iím looking for the communityís input to determine what to do at this point Ė should I keep it or leave it? Hereís a breakdown of the car:
  • 2008 BMW M3 Convertible (E93), Manual 6-Speed in Alpine White with Fox Red Novillo Leather Interior. Manufactured June, 2008.
  • 135,000 miles (2nd Owner, purchased in Feb 2012 as a CPO with 45k miles). Daily driven (90% freeway); never tracked.
  • Meticulously maintained inside and out (personal mechanic is a BMW Master Technician); garaged with very few signs of wear.
  • Switched to Liquid Moly 10w-60 since 100K (oil change every 5K)
  • All equipment works and is 100% functional (except the engine). The convertible works as it did when I purchased Ė flawlessly.
  • The Throttle Accentuator was replaced at 125K miles (April 2017). Prior to that it went out at 90K miles (August 2014).
  • Replaced the battery earlier this year (January 2018) with 130K miles.
Factors for Consideration
  • The car is paid off. As of May 2018, my M3 with 135K miles in the Los Angeles market is fetching anywhere from $15K to $10.5K Ė if it was operational, itíd most likely garner $13.3K.
  • Given the effort and risk to take fix the engine, it seems better to replace it altogether with something slightly used, but preferably new. I believe the engine costs anywhere from $7.5K to $10K. Itíd probably be smart to upgrade the rod bearings at that juncture, tacking on an additional $1K. Finally, I assume labor will cost around $1.5K for 12 hours @ 120/hour. I project the cost to fix the car will end up being what the car would be worth once itís up and running.
  • I have a trust-worthy mechanic (as previously mentioned, he works as a BMW technician for a high volume dealership). He intends to open his own shop and recently filed for an LLC. Very shortly, heíll also be licensed to buy wholesale parts (and possibly a new motor?).
  • Over the past year, I noticed my insurance is steadily increasing even though due to the rising cost of parts for the car.
  • Keeping it would force me to reconsider using it as my daily driver, however why own a car if you canít drive it? Itís doable, but not preferred.
  • Itís hard for me to consider an alternative that has all the features I bought this car: white with red interior, stick shift, rear-wheel drive, high-revving naturally aspirated engine and a hardtop convertible. The only car that is ďsome whatĒ comparable is a Honda S2000, which Iíve owned before and would consider it again.

Questions
1. Should I fix it or sell it? The cost to fix the car will be what the car is worth (if running).
a. If fix, how much do engines go for (new or used)? Unable to find pricing online.
b. If sell it, how much do rolling chassis go for? Unable to find pricing online.
2. What is your next car after your M3? Would like to hear otherís suggestions as Iím having difficulty coming up with a comparable alternative.

Thanks for viewing!

Oof, that's a tough one. I hate to say it but I think I would shop it to parts dealers or list it as-is on craigslist. See if you can get at least $5k, maybe up to $10k? I have no idea what a dead engine'd M3 goes for. If you really love the car though, put a new heart in her and keep driving.

I'd offer to buy it if you were local to me. You'd be better off selling it as is to be honest.

A few things to consider:

1. $1.5k labor is on the low end. Probably looking at $2.5 - $3k. Part of this is factoring in the cost of oil, coolant, power steering fluid (expensive af), transmission fluid.

2. At 135k, it wouldn't make sense to reuse the original clutch. Being an '08, you'd need an '09 flywheel and clutch. Maybe you can find that used for $500.

A 60-80k mile car with a blown motor '09+ usually goes for $8-$12k. Your mileage affects that. Also you're sort of ruling out the racecar guys being a vert. That'll limit the ability to sell it as is.

For a used motor:

http://www.m3post.com/forums/showthread.php?t=1486859

Maybe you can work out a deal as cheap as possible with this seller. Otherwise a 50-60k mile motor would usually run you anywhere from $7-$10k.

Sorry for the misfortune. Too bad you were not closer I would consider the rolling chassis.

deansbimmer if you decide on replacing motor. His engines come with bearings replaced. Other option is to part the car out. If you have a place to store the car and the time/knowledge you would do well on a 100% part out. Good luck and very sorry to read this.

Not sure I understand the issue. The motor seized? It's dead? You say it hasn't detonated yet. If it just needs bearings plus correcting some other minor issues, why not have your mechanic do a compression/leak down test. If there are no issues with that I'd do the bearings. I agree, if you don't drive these cars six days out of the week, what's the point? I've got 113k on my e90. At 105k I had my shop do the bearings and anything else that needed addressing while they had the car. They did the valve cover gaskets, power steering pump, the bake lines and some other minor stuff. $3000. That's a whole lot better than the hit you'll take if you sell it now and way cheaper than a used motor. Just my 2 cents.

The cost of the repairs will be less than the cost of another car, particularly one that you will want to drive. Moreover, if you sell the M3 and buy another used car, what guarantee do you have that that car won't need repairs?

Sorry to hear this man! Are you sure the engine is toast?

As for other cars, that's a pretty select criteria. If you've already had an S2K and are considering one again, I guess you don't need back seats. In which case I would look at a 996 Carerra or a 986 Boxster with removable hard top.

Those suggesting replacing bearings and fixing the existing motor need to understand that once there is audible rod knock, it's dead. You *must* tear down the engine as there will be crank and/or rod damage and bearing debris throughout the engine that must be removed. I can't tell you how many calls I get from people who cut corners without a full teardown and are now dealing with oiling and Vanos issues from the fallout.

This is a tough decision nastynogales. The money you would pay to have the engine professionally replaced (or properly rebuilt) would put you in a close to negative equity situation. For a high mile 08 you might end up taking a smaller loss by selling the car for parts (or parting it out yourself if you have the knowlege, space, and patience). The side issue with parting it out is that buyers are not usually interested in high mile early model parts.

Your best financial outcome would be from parting it out yourself. But that's not for everyone. In my experience it takes up to a year to liquidate every last nut and bolt from an M3 if you stay on top of things. If you decide you would rather liquidate it as is, my shop may be interested in buying it.

Are you really sorry. I started a thread about this very same issue and your comments made it seem like this was not an issue. Now your on this thread tell the OP that your sorry. How is sorry going to help him?

were you testing your oil periodically?
were you considering the rod bearing replacement?
did you think it was an overblown issue and just ignored it completely?

i'm not trying to rub it in or kick you while you're down
i'm asking this seriously because i just purchased an '08 e90 M3 a few days ago and i'm contemplating doing a preventive rod bearing replacement

What's there to contemplate? Just this week we already have 2 threads wiyh failed engines. You can take the attitude like some have stated that this is all a big con started by independent shops to take money out of your pocket.

I did mine the next day after purchase. I hope there is no issues down the road.

You didn't seem that concerned then. It just shows your a hypocrite. Yes it did feel good to get it off my chest. I'm sure your sorry will go a long way.

Calm down, sir. Fighting isn't gonna help anyone.

It's not Montaver's fault that he is sorry or that OP's engine blew up.

And regarding getting RBs done - another guy got his engine blown up after driving approx 10k on BE bearings. Maybe it was the assembly maybe it was the bearings - still. If shit has to go down it will go down.

OP - it seems parting out seems like the correct thing to do at the moment. Keep the forum posted - lots of experienced people here who can help you in one way or another.

Did you have a link to this post? Would be great to know the root cause of the failure.

OP, I apologize for the off topic reply, but here's the link

IMO I would part it out if you have access to bubble wrap and boxes and tools and storage and know how, otherwise sell to someone as is.

Does it still drive? valet it in a bad part of town. /kidding

Maximum cash = Part it out
"Quick" flip to get into something new = Sell as-is
Have your heart set on this exact car = Replace/rebuild motor with a bad fix cost to value ratio

I feel so bad for OP. Car is paid off, driving top down enjoying the V8 and boom its all over. I wish you the best OP.

S2k is fun but its not a do-everything car like the M3.
