Second oil change and a noticeable amount of metal flakes were found enoguh to make me worry. This will be the second MMR roatating assembly that has had some type of bearing failure before I hit the 1000 mile mark and got a dyno tune.
I pulled the motor and found this on # 5678 heat marks. So I pulled caps and the bearings def have some wear but not catastrophic failure but look at the heat on the back side.... what do you think causes this I'm running MMR oil pump gears
