[Vwdiesel] [Audi-VW-Diesels] Head Bolts and more

[Dave Cook]

I have three types of bolts from three engines in my garage:
11mm Allen Hex head.  Bentley indicates this is non-stretch
11mm 12-point allen like head.  Bentley indicates this is a stretch
12mm 12 point socket head (takes a 12 point socket to remove)

I wish I could remember who said gasser bolts were somehow better.  I wonder if the difference was stretch or non-stretch?  (And the poster assumed that stretch was gas and non-stretch was diesel.)  This is my guess.

Hmm, so do I use the reuseable bolts, or do I use the stretch bolts that are presumably on the way?  My inclination is that VW thought the stretch ones were better and that is why they went that way.

Also, I just noticed that the rod bolts are stretch bolts.  Wish I would have realized that when I put in the big order including bearings. 

I don't have to buy the bearings if I choose not to.  What do you all think?  Any way to judge the condition of the bearings without taking it apart and having to replace the rod bolts?  

I am starting to think more and more about just rebuilding it and maybe driving the car for awhile.

Thanks guys!
