Over on the 1-series forum I have just read what I believe is malfunction due to oil starvation on a N55.

Anyone planning to make a weld-in baffle for our engines?

I'll be on the list for a pre-order!

First I've ever heard of this and this motor has been around since the E90 days. Probably a rare thing.

AFAIK you just run the M2 pan/baffle setup. https://f30.bimmerpost.com/forums/sh....php?t=1893538

It is rare.

Only affects non xdrive n55 -- from what I've seen mostly from track use. I am no expert, but I believe long left turns can starve the engine as the oil settles with gravity to one side of the pan away from the oil pickup.

Again, no expert.. Just what I recall from reading about the issue.... xdrive oil pan apparently acts as a natural baffling system... if you look up the part numbers for the n55 oil pan youll see the difference.

Can we run x drive oil pan on our 2 wheel drive cars?

True. Hard STRAIGHT line braking will see oil pressure drop to 22-25psi. During my own track days (running Cup2 and AD08R) this was not exacerbate by left turns. I think people will be safe running DOT tires with proper oil level.

T7 and T8 are the worst as I remember. T7 is trail braking into hairpin left and T8 is full lateral G under load.
