Blown motors, Rod Bearing failure S65 Registry.

[Brownd3max]

Wtf man? That reeeally sucks big time. And I'm sitting here right now in a hotel room down the street from MRF Engineering (Malek) after just dropping off my M3 w/83,000 miles, so Malek can change MY RB's and motor mounts. I don't know what one of the previous posters meant when he said VACs are "$hit"- I sure HOPE they aren't! Malek shoots for 2 thousandths (.002) clearance with these, which is about double the stock setup. Should help, fingers (and eyes) crossed!

There’s nothing to “shoot for” with RB replacements unless you’re pulling the motor and tearing it down to make adjustments, or buying different bearings. VAC’s extra clearance Clevite bearings should yield a .0020 nominal clearance. The BE bearings should yield about .0024.

Also should clarify that .002 is not twice the factory clearance. I think the smallest nominal oem clearance was around .0014 with the old copper 088/089 shells (Off the top of my head). There’s no way to know in hindsight what bearing clearance your engine was originally assembled to.

The important thing is that you’re installing fresh bearings. VAC or BE should both extend your engine’s life.

Sorry if I misspoke- I meant to say that the new replacement bearings "Should Give" around .002" clearance. And I guess that's approximately 50% more clearance than stock, + or -...Anyway, good luck to me.

Supercharging scares with me with these cars.

And this a big reason why I haven't, even with BE bearings.

I have also thought about it. Drove a buddies with a 650HP SC kit and it was wild!!! But I worry about my engine without one. I would go crazy with worry if I had one!!

They are fun though...

I've been contemplating a Harrop SC for a while but can't risk it on my daily.

Some pics from my recent S65 grenade. Almost have my new one broken in already!

What happened here?

So... the SA at the dealer claimed that the rod snapped and ejected. But when I asked them why the rod snapped, I haven't gotten a good answer out of them. they did provide really good service in working with my warranty company though.

Im assuming it was a MB and/or RB failure based on how catastrophic and without warning the engine blew up.

Is/was your car stock ?
Did you heard suspicious ticking or rattle noises before it blew ?

No suspicious noises, Temps, pressures, fluctuations, etc. The original engine was flawless until it blew up.

I have ESS 650 kit and cat back exhaust.

I had about 25k on the engine with the SC installed, no issues.

I stick to No greater than 5k mile oil changes (10w60), and always allow the car to properly warm up before stepping on it.

No track days just DD.

Ok I see . I suspect it was your 650 kit .
Thank you for your information .

So my kit which is probably on hundreds of M3s trashed my engine with no other explanation?

Or do you mean that the SC kit accelerated the RB damage leading to failure?

How are you getting a warranty replacement with a supercharger?

Great question. Sometimes I don't ask questions when something seems to be working out. PM me if you'd like some more details but I honestly am shocked everything worked out with minimal financial impact.

From your pics I saw your rod blew in pieces through your S65 block . Usual if the S65 is stock the major cause is accelerated (premature) wear of the bearings , but in your situation it was (probably) by the extra load (torque) from your 650 kit on your rods .
Keep in mind that the S65 is a light weight aluminum motor block with thin cylinder walls and actually it's not made (it can not handle) the extra torque from a SC kit (the 650 kit is no joke)

Of course this is one of the theories , but I see no other explanation.
I saw over the years a lot of bearing failures from all over the world . And it's very clear , something is seriously wrong with the S65/85 bearings . Even stock !
That's why I think that a SC kit on a S65/85 engine is like looking for trouble .

In Europe or over here in Belgium , this would be a miracle ...
Great to see he got one in the US under warranty .

[deansbimmer]

These blocks can handle a 650 SC just fine. It’s still a bearing issue.

[pbonsalb]

ESS recommends a preventative maintenance rod bearing change for a VT650 kit. I am guessing the owner did not follow the recommendation. But at least his aftermarket warranty company is honoring the warranty despite the significant modification to the motor.

[deansbimmer]

While we're on the subject recent holes in the block... I've got one for the M3Post files. Catastrophic Rod bearing failures on cylinders 2 & 6.
