Rod Bearings were ready to give up the ghost.

[GG///M3]

Well a few months back I was looking into replacing my rod bearings as I would be doing a few HPDE events this year. The WPC rod bearing group buy popped up, and I couldn't resist getting in on that.

A little history of the car. I picked up the car in Sept 2013. Before purchasing ran the vin with BMWNA, and they gave me the number to the dealership that serviced the car. When I called them they had informed me that the rod bearings were replaced at 20K miles. The car currently has 163k miles on it.

This Tuesday I dropped the car off at Max Psi to have the rod bearings replaced with the WPC treated stock bearings, and arp bolts. Now keep in mind the previous owner said he changed the oil every 5K miles.




Wow am I glad I went ahead, and replaced them.

GG if you don't mind me asking, what did they charge you? Did they have any issues with just replacing the bearings ?

Wow a few of those are in seriously bad shape. Good call.

Fundamentally is the bearing issue on NA S motors a matter of improper clearance? Wrong recommended oil weight? Generally weak/poor oiling? Curious…

Poor oil circulation and improper clearance. The clearances are too tight.

So it’s just like water pumps…they fail and fail, yet BMW doesn’t appear to make necessary revisions in terms of clearance?

The relatively poor oil circulation can somewhat be excused just due to economics (expensive to really set up a nice oiling system in a mass produced street car).

Never knew water pumps were much of an issue. At least in cars after the e36 chassis.

Perhaps i'm biased as they get absolutely wrecked on N54s with how hot they run...but yea, they fail far too often for a mechanically simple part.

I'm really glad you replaced them but was the labor and the cost?

Total to replace?

Parts & labor was about 1200-1300. Keep in mind I bought the parts myself, and got the rod bearing with group buy pricing(so figure if that wasn't the case the bill would be higher)

What about just labor?

[Mike@VAC]

Good call. The guys did mine at 60k to be safe.

Did you upgrade the oil pump while in there?

How much would vac charge?

[Mike@VAC]

How much would vac charge?

$499 + core for the pump. $$$ well spent, esp if the pan is down.
