I know the world likely doesn't need another torque guide but I have been keeping a doc on my iPhone that I use when I am restoring E46s. I have leaned heavily on the two big efforts in the past:

The Ultimate e46 M54 Torque Specs Thread
Ultimate BMW E46 M3 Torque Spec Guide

This is also useful:

Very useful thank you Archbid. I have a question on the oil pan bolts. I see there are 2 listings as 8.8 and 10.9. All of my bolts have 8.8 on the head so what are the 10.9 ones? :dunno:
Every source I found listed both, so I put it in when I was preparing for the job. I only have 8.8 as well. Every time I do a job I make a list of all the fasteners and their torque settings so I am not doing web searches or looking in the Bentley in the middle of the job.

Thank you so much! I will be using your guide as I have so much apart right now on my X5 just waiting on the oil to stop dripping in the front left corner seam so my sealant will dry properly without oil contamination when I put the oil pan back on. 3 days now and still coming down. :banghead:

Take the tip of a rag and wipe the inside edge of the block up about 1cm. The stuff dripping from the driveshaft and pump won't be an issue, just the seeping down the walls. Wipe the inside edge and buy yourself 10 minutes to get the pan in place.

Yeah I am probably just being over cautious and paranoid. The instructions on the Dreibond 1209 sealant is 3 fold torqueing. 3 ft/lbs initially. Half torque at 1 hour and final torque 6-24 hours later. I just don't want any oil in the sealant, God knows I don't want to do this OPG twice.

I have done three oil pans since January. It is one of my least favorite tasks.

Though oddly the only one that always makes me angry is the damn hinge cover slides and springs on the convertible. ;)

BTW, I highly recommend a digital torque wrench if you are going to do a lot of DIY, if only because you can do Nm as your default. Tekton wrenches are fine, but they are made for ft-lbs/in-lbs and that is just irritating.

I bought the Craftsman 3/8 Digi-Click for the job. It will display Nm, in/lbs or ft/lbs.

I think $150 is retail as Archbid suggested but I got mine new off a fleaBay seller for $89 delivered. :thumbup:

It is about $150, and it is the one I use. Only gripe is that it only works clockwise. Otherwise perfectly useful.
..and the screen readout is a tad small. and that’s on my 1/2” big boy.
ratchet head could be larger too.

Arch, I think you have a typo in the oil pans specs. For the 8.8 bolts you have a higher torque than the 10.9 bolts, and the imperial units don't work out.

My Bentley has 10nm/8.8 and 12nm/10.9 for the m6 bolts and 22nm/8.8 for the m8 (xi oil pan).

Still a discussion on the 2 different torque specs for the 8.8 and 10.9. I wonder if the 10.9 bolts are the 3 torx bolts from the trans bell housing to oil pan? If not, does anyone what would those torque specs be for those 3 lateral fasteners. :dunno:

I hear you. I changed mine about 3 years ago or so on the 330 and I am getting ready to do it on the 323, it's a lot of work and time consuming but not difficult.
