Other benefits:

-No undeserved //M striping.

-Vegan, no animal skins, milk, eggs, or beef involved

-under $15

Where you be getting that?

Cored out the inside and added lead

I think I paid $12 for the knob brand new

[patsbimmer1]

So you saved $50ish but gained lead poisoning...

Dont you worry, buttercup, I wear a full Hazmat suit when I go fishing or to the gun range and I can drive my car with it too. Folks will think im the Stig!

[KaiserRolls]

It doesn't feel the same in your hand

Phrasing?

I received a few final pieces to finish rebuilding the oil pump. The new outer rotor has a .002" larger diameter than the old one which in itself will increase/restore pump performance substantially.

The overpressure relief springs had an evident difference in length and stiffness . The new one being longer and stiffer and better for preventing any early bleed-off of pressure. The new o-ring was badly needed as well.

The Achillies upgraded pump shaft comes with a bolt instead of a nut, a new sprocket (has flats instead of splines, a bmw sprocket will not work on this shaft) and safety wire.

I also received the little cam tray dowel I needed. Lets see if I can finally get these stupid camshafts installed this weekend

Intake cam torqued

Just kidding, stripped another stud.

I got a wave of motivation, went out and fixed the stripped threads, re-installed the cam.

Guess what happened?

Yep, stripped another one!

So are you sure you have the proper torque specs? I don't want to seem like I'm second guessing you but I find it very hard to believe that they would put a torque spec that dangerously close to the yield of that thread in aluminum.

11 foot pounds/132 inch pounds, certified calibrated torque wrench that goes from 40 to 200 inch pounds so I am right in the middle of the torque wrench capacity and everything to

No

I want to believe you aren't doing something wrong, but I'm having a very hard time doing so. 
I've rebuilt many of these motors, and the only time I had a stripped thread was the small torx screws that go into the timing cover. 

Those cam caps are a glorified hand tight, so I don't quite see how you are having so many issues.

I've been a ding-dong many times before but I promise that in this instance I am 100% right and the cylinder head threads are 100% wrong.

Mitch mentioned my torque values may be in yard-pounds [emoji23]
