Rod-Bearings

Hello,

I have a 2006 e60 M5, it has 96000 miles on the original engine and I have had the vanos and vanos solenoids replaced recently, I have had all this work done at our local BMW dealership. I purchased the vehicle a few years ago from the original owner who also had all services done at BMW/Concord.

When they replaced the vanos, we decided to do the rod bearings as we were in there so why not. Well, the repair went very well because there was at least 2 spun Rod-bearings and the other 8 looked worn too.

What happened next is a mystery, and to be honest the dealership up here in Northern California seems a little over their heads with this car. I've pretty much had to do everything's 2 or 3 times. When the vanos was failing, they suggested only replacing the high-pressure line, this costing mostly labor, seemed like it was the solution; only to have vanos fail ultimately anyway. So for a third time, we finally get the vanos replaced. And that's when they heard the tapping in the pan. So they suggested removing the suspension again and opening the oil pan. Like I said, everything 2-3 times here.

But now after 500 miles, the engine begins knocking and tapping again and they're telling me it's Rod-bearings again.

Now there's discussion of a full rebuild etc. but the engine is as smooth as silk and full of power... There was some particulate in the oil, but that's no longer there after several recent oil changes from repairs alone.

Could I ask you guys to give me some advice/information so I can feel certain about what I should do?

Why would the bearings fail so fast again and is there something maybe they're doing wrong with the install?

They are wiggling a bit but I Have a great relationship with them, although I'm beginning to think they may not know what they're doing with this s85 V/10 engine.

Please let me know what you guys can do... I would pay dearly to have any of you professionals or service techs to consult their technicians! If you work for a company that specializes in these repairs, I could easily get your contact info and consult you via telephone, email or however works best. I would additionally cover any costs for your "Professional" time with the technicians.

My M5 is in excellent condition over all, I am willing to put any amount of work into this vehicle to get and keep it right, but I don't want to waste money while others make the wrong repairs or whatever. I live in a remote area and so my options are limited with the local dealership I guess.

If a bearing was spun, then just replacing the bearings won't fix anything. The crank journal is probably scored and will just spin a new bearing.

Unfortunately, what these guys said. You need to go to a specialist for this. If you have the budget to do the engine, you should see Troy Jeup or Jim Colley, who are well known for rebuilding these engines.

Update

Well, for anyone experiencing this problem... it was in fact terminal and the car does need a new engine!

That being the bad news, the great news is that it has led me to Troy Jeup! The car was shipped to him about 2 weeks ago. Not to mention he's a very cool guy and we've managed to strike up a friendship. I'm telling you he has to be the easiest guy to work with I've dealt with in a long time.

So, he gave me the choice of a stock rebuilt 5.0 engine or a 5.2 or 6.0 stroker engine with 600+ and 700+hp respectively for each engine!

I have chosen the 5.2 stroker engine and he's going through my SMG and I've requested a new clutch while he is in there too. My m5 is in very good physical condition but these engines have issues with the crankshaft and bearings.

If you are having any issues with your vanos, vanos solenoids or pump... make sure while they have the subframe out that you check those bearings and crankshaft too, because I spent literally $9000 for all new stuff only to have technician tell me they think I had a spun rod bearing after the whole thing was put back together!

To bigscore, that's just part of owning a fast powerful beast. If something like this throws you off, maybe stick with Honda or Toyota...

The standard axxhole reply..

Don't be so smug......

What makes you think i own a Honda or Toyota.....

2006 M5 isn't even expensive to purchase ....i would look for a 2008 or better but that doesn't mean i look forward to possibly having to spend a third of the cost on a single repair.

Show me 1 person who looks forward to having to spend $X000.00 in repairs on a car. That being said ill probably scale back to an E90 M3 sedan and yes ...i know they have issues too.

SMH

I mean I run 8s and make 1400+ with my GTR, only problem I had was a 200 dollar tow and 200 dollar bolt that snapped off my rear hub at 1200wtrq after 17,000 miles. Other than that zero problems. I broke a drive shaft with 9.9 power on GT800 turbokit and R888s very hard on my trans so my outta pocket costs for the GTR over 2 years, and 35k miles is 2900 dollars

These issues are especially exclusive to the e60 era m5, plenty of cars make the same double triple quadruple the power and have no issues.

I try to say its akin to owning an older Ferrari you are paying for a last of the era kinda car, and something that is near one of a kind, and it unfortunately was a few years too late to get much better reliability like the s63tu has. Its up to each individual to decide if they can stomach the HIGH possibility [not 100% possible but I'd say its over 50%], they'll have 5 figure repair bills.

M5Fed has had good luck with his car, I'd preface that with he's an exception to the rule, rather than the rule. I've yet to see someone locally [myself included], have 5 figure + repair bills and some sort of massive issue with the car be it an 06, 08, 2010 car. It really is just platform-sentric and when you mix the v10 and SMG you're gonna have problems more often than not.

One reason I try to frequent the e60 boards so that people hear both sides of the experience and if its really in your budget or you can stomach some of those hiccups than that v10 sound and rawness is near unbeatable anymore

@SuperTerp, that's about the best way to put it about the E60 M5. But what a man do for love, one cannot put a price on. Don't tell my "boss" I said that.

@m5mazzotti, how has it been after the rebuild?
