All torx. 29 total.
Quantity, size, part number.
(17) M6x22 11137800619
(4) M8x30 11137800621
(4) M8x50 23001222887
(2) M6x60 11137800622
(2) M6x100 11137800623
My subtotal from FCP was $49.24!
At least it's free when I do it again in 100K miles.
As far as I know, there are no manuals in circulation for oil pan work on the M57 and I could find absolutely no information, so my best inference for torque values on these bolts, all grade 8.8, is going to be 10Nm for the M6 bolts and 24Nm for the M8 bolts. These bolts are steel (magnetic) so I would not do the final 90° / 180° tightening that is procedural for the aluminum bolts on similar engines. I'm using loctite just incase and tightening everything in an pattern just like head bolts.
This is what I found for aluminum pan bolts.
M6: 4 Nm + 90°
M8: 8 Nm + 180°
Use any of these torque specs at your own risk. I don't know what's right. If anyone knows better, please correct me, I'm probably going to do this in about a week. Beforehand, I will be tapping scrap aluminum (to mimic engine block) and torqueing these old bolts down to various values to see how they fare. I'll update with my findings.
