Peter came to visit tonight, so the sump came off and we got the first glimpse of the insides this evening. And I was stunned at how good this 100k km motor looked inside. It just goes to show what's possible if you're following a strict flush and oil regime.
This motor had 1l ATF added to the oil prior to its last service that was 4000km ago. It ran this for 200km and then the oil was replaced. Since then I've been running 0W40 LM oil in the car.
And now for the part that I didn't expect...
Lucky the crank still looks fine
This is only cylinder 7 and 8's bearings removed. We will remove the rest tomorrow evening.
To say I was surprised by what the bearings looked like is an understatement, and Peter is of the opinion that some of the rest might even look worse.
For those that still believe that this is all a storm in a teacup, I urge you to get it done. Looking at the condition of these bearings I can't imagine I would've had too many more miles on this motor. And it's not that this motor is sick, I've got Dyno results that prove it's still healthy.
The point is that you don't know till you check it out - and I would check it out if I'm over the 80k km mark. It's a relatively cheap thing to replace, when compared to replacing the motor and all the pain that that involves. I can just thank my lucky stars that I intended to do this since I decided I'm getting an M3.
Get.It.Done. That is all...
