Why a 750? The M62 seems like a far more reliable plant with the same HP figures. Never saw the allure of the V12.

Lol, because I want a v12. And already own a v8.

Basically my thought process went, "I want a v12 car before there's none left and we're all driving hybrid 4 cylinder turbos. What's the best option for me?"

... And ended up with e38.

The allure of the v12 is achieving the power smoothly and effortlessly. I'm fully aware it's not faster than the m62 e38.

Never seen anything to indicate the m62 is significantly more reliable than a late production m73, though.

... I do like the 12 with muffler delete. I'd do it via cutouts, though, not full time.

Huge discovery today that'll dramatically improve the quality of my life. Turns out, oe iPhone 6 holder. Didn't know what they were for for the first 15 years, as they don't hold anything else well :P

Nope!
So how did you diagnose it?

Well, there's only a limited number of places where alu and steel are in contact. I had done all the other chain guides, so was fairly confident it wasn't them. I had (foolishly) skipped the oil pump chain and tensioner (short chain, how much could it stretch... was my thought process), so it was still a possibility. And easy to check (drop oil pan, pop cover off look). So, I check it, it was the problem (that's where that pic came from), went through with the repair.

I'm curious which of your mods and maintenance items on your beast brought your curb weight below 3800lbs with stock exhaust intact?

And for replacing the timing chain guides, is it an item that should be done based on age, or based on mileage?

Thanks in advance, and great thread!

Mostly by measuring actual weight instead of curb weight

Weight reductions on my car: wheels, brakes, suspension, CD changer delete, secondary air delete, aux washer system delete. Not a ton-- I'm really not focusing on weight on the M5. I will be doing headers, which should add some extra lightness, but that's really just a side effect of what I'm going after.

Chain guides: I'm not sure I'd do them preventatively again. While the project overall was useful, my original ones still looked pretty brand new. Going forward, I believe I will do it in response to
1) increased steel and alu in the oil, verified by dropping the lower pan to see if there's plastic shards in there
2) Increased chain rattle, verified by dropping the lower pan to see if there's plastic shards in there

Thanks for the info. My lower oil pan gasket is leaking at the moment, so when I replace that, I'll have a look to see what's going on along with the UOA to see change in numbers. My car is at 84K miles, but is an 03, so I'm on the fence about doing the chain guides as PM strictly due to age of car. I guess its good to know there are ways of keeping an eye on it before catastrophe.
