Jeff Rakus --- I Hagar suggest that you read Loren  ---in archives. ----Personally I do
not use Bentley procedures ---- BUT the way I do it requires the VC to be removed a LOT of
times. -----tightening of Head-bolts on a VW Diesel?  --super critical IMHO.

Many years ago I started to use EPOXY  on cylinder heads---- and I will NEVER stop now.

3M structural (gray)  ---- and yes I did wonder ? --next time how the hell do I remove
cylinder-head ?  ------- not to worry if you do it right ?  ----it works.

What is so special about STRETCH bolts ?  ---NOTHING  ---all head-bolts stretch ---BUT the
factory found that --when a bolt hits solid resistance ?  The stretch is according to
pitch on thread. and they posted the optimum.

OK we could say that the bolts are of a better grade.--notice that if stretched beyond
yield ? new bolt must be used.    So you want to know about tensile and yield strength and
what not ?   lets see if we can smoke James Hansen out of his Canola fields. ---I think he
has a laptop   out there in the Rapeseed GMO.

I know he said he has a library right in the Cab. Funny thing I had the use of a Tinus
Olsen testing machine some years back.-----so I know --BUT I do not know how to write it
up here.
So what exactly did I test on that BIG machine ?  --the steel spars that I used in the
Bensen Gyrocopter.
That was about 1963  --and I am still here ?   --JA ?   so the steel was ok.
