Head Bolt, Stud Torque Tech Tip - Importance of a proper washer - Interesting

LOL! That is good stuff. So do you do this for other shops, or do you just restore and turn stuff around and resell it?

And yes on the paint.... I looked at your pix and the indentation looks the same, just that the washers' anodizing got transferred to the head on the upper ones. Obvioulsy, the AL material is getting a bit brinnelled or maybe even crushed. Looks like the washers were not there, or maybe like the original article here, the washers spun some with the bolts/nuts. I guess you get to try sanding the bottom sides down and not lubing them, like the article recommended.

Thanks for sharing the info.

I just do the rebuild stuff for me and for resale if I come across a machine at the right price. I have a two car garage in which my side was a machine/work shop for the last 17 years. I had to move/sell/give away a lot of stuff to be able to get a car in on my side. Wife won't give up her side during winter and the lot layout won't allow me to expand. Getting close to retirement and hoping to come up with a few widgets to make and sell to keep me busy. I've been repairing BMW E39 M5 oil pans for several years because parts for those cars are crazy expensive.
