Im hoping nothing else brakes in the next year or so, debating a dinan tune since they are only $600 now or upgrading to an M with better suspension.

how bad was replacing the oil pan gasket?

N54s should add a oil pressure gauge. N55 has oil pressure monitoring out of the box and can be logged on MHD.

what causes a spun bearing? and how do you know you spun it? ... would you recommend the n55?
