Can a V1 vs V2 diff be differentiated by the round vs. "scalloped" input shaft? Also can V1 diffs OPF's be swapped to V2 diffs and vice-versa? From what I understand V1 diff had the short OPF on the passenger and V2 on driver's.

I have a V1 diff (short OPF on passenger side), it also has the round input flange.

Round:

"Scalloped"

It's been ~25K miles since my car's valves were last adjusted. What is a reasonable # of hours to "just check" if a valve adjustment is needed? Not the full job, just a spot check.

I think the mechanic I've contacted is quoting high 💸

Do our cars usually burble when downshifting/going off throttle? Been dailying the M3 lately due to some scumbag hitting my other car and started noticing some extra exhaust noises, especially when I keep in 2nd and get off throttle.

To just check, maybe 4? 5? Depends on how familiar the mechanic is with the engine. A full valve adjustment usually takes me around 5-6 hours, about 4 of which are measuring, swapping shims and remeasuring. Rest are spent cleaning up gasket mating surfaces, disassembling, reassembling and (inevitably) cleaning/fixing other stuff.

BUT, I tend to work slow, especially during valve adjustments since I've dropped shims before. An experienced S54 mechanic might be able to get this done in 3-4 hours.

You "check" them as part of the job. Maybe all will be fine, maybe some need adj, maybe many need adj. That's the job.

Would checking really save much vs. just having the whole thing done?

No. It makes no sense. Esp when many people/shops, like myself, charge a flat rate for the job.

How does the heat sheild on top of Sec. 2 go on?

When I took my stock Sec. 2 off 3 of the 4 studs that hold the heatsheild were broken and I was left with 5 of these little "steelwool washers", one nut and what appears to be a non-OEM washer.

My question is how is the heatsheild placed on Sec. 2? Do the steelwool washers go only on top of the shield, only on bottom or do I need 8 steelwool washers for top and bottom?

I likely won't be able to fit the shield regardless as my aftermarket muffler raises Sec. 2 too high so even with the OEM pipe it won't fit, now with a larger (SS) Sec. 2 the gap may be even smaller.

Hopefully if it doesn’t fit I can continue to run without it without too much consequence but if it does fit I'd like to know how to mount it.

8.

[Cubieman]

Anyone happen to know where one might source something close to these washers for Sec. 2 heatshield?

[Tbonem3]

I think Rob found a good substitute. IIRC, it was Rob, in his street build thread if you go to the part where he's fitting the oversized SS sect 2.

In my experience, the aftermarket, larger pipe sits too close to the driver propshaft flange on the diff, and if you install the stock heatshield with washers underneath, the heat shield will kiss the diff flange. It probably is dependent on other factors like how the sect 2 meets the sect 3, and how you space out the crossmember braces on which the sect 2's rubber hangers sit.

I installed the heat shield with only 4 wire washers on top, to give myself about 1/4" clearance.

hey guys,

Saw this on mpartsworld wide on IG... https://www.instagram.com/p/CjJKNZzJuz3/

what kit is this? I've been trying to do some research, because it looks like a fantastic price, but i don't want to jump in without doing the proper nam3f member research. lhahah

I couldn't find any info on hte 362mm rotors other than they are the same as AP's bbk.

Yeah, I was eyeballing that as well, curious as to what it is too, didnt look like the standard 996 "big reds" but I may be wrong.
Don't worry, I won't be buying it regardless.

I think they have actually multiple kits, I also found the same kit eBay for $200 cheaper.
