I know...ARP. I bought the OE bearings and bolts awhile ago before the Clevite bearings came out.

I found the torque procedure:

6nm
20nm
130 deg
Full turn loose

6nm
20nm
130 deg
Full turn loose

6nm
20nm
130 deg

The procedure mentions lube. I would imagine that is clean 10w-60?

What if I use Mobil 1 0w-40? Will the bolt get loose? Kidding!

I am also going to install OEM bolts. The instructions call for "Replace screws. Screws washed and oiled". I am so used to ARP bolts that I was going to use their lube, but perhaps you are correct and engine oil should be used. The torque sequence is so weird that BMW may even recommend some German butter.

So you tighten it to 6nm then 20nm then 130nm and loosen it all the way and repeat it 2 more times and then finally torque it to 130nm?

I don't recall the full turn loose step. I do recall loosening after the first 2 sequences so the sequence could be repeated prior to the 3rd and final sequence but it was 3 years ago when I did this.

It's a lot of steps. Like 11 per bolt versus 2 or 3 for ARP. Times 16 bolts.

Crap...copy and paste. You don't loosen the bolt for a 3rd time.

I just soaked the bolts in some 5w40 i had lying around. Much easier job on an engine stand.

The OE process sounds a lot worse than it actually is.

I have done it with stock bolts and with ARP. ARP might save an hour.

Not the most fun if you aren't dropping the full subframe. If you are using oem bolts I recommend just dropping the full subframe and taking the extra time. Less hassle and shit in your way when trying to do the 130

Even if you're doing ARPs, its way easier to drop the subframe. Its only 6 more bolts - 4 control arms and 2 tie rods.

I dont think the fast guys, the ones who have done it several times, drop the subframe. They are doing the entire job in under 8 hours. I have only done it twice, once dropping the SF and once not. I would not bother dropping if using arp.

Unless the torque changed, it is 20Nm, not 30.

The only place I've seen 20nm is in the wiki.

The info I posted here previously is info from AIR (former TIS), based on my VIN, but I know it is the same for all S65.

Bore could distort. Would have to test on a rod.

Even though you went 50% over you should still be OK. A lot better going over at that step than going 10% over on the last step.

Realized I was on the wrong page on the work manual site...I was looking at the main bearing page. That's what I get for trying to find it on my phone at midnight.

I still feel ok about it. I took plastigage measurements and I was around .002" and only 2 cylinders were between .0015 and .002. I was pretty good about hitting 130 deg spot on each time with no slipping.

.002, the magic number. Nice!
