I am certainly interested in this.
I hope anyone that gets more information on these will post it up for all to see. I am curious to know the cost of these things, if he can build more.

I'm using 12.9 cap screws and have installed one set on Blazin when we replaced the engine.(see post, oil in coolant) in seems to be going well and we didn't do any modifcations to the pan. It is made of 3/4" steel. When doing a search for girdles on e-bay they all seemed to be alum., am I not getting something?
These are pictures of the prototype girdles. They fit on an otherwise unmodified motor, including the pan. The final version still does, but is 3/4 inch thick instead of 5/8 inch. All five mains are covered. Unfortunately, we don't have pictures of the 3/4 inch version because it is 1000 miles into use on the truck, and pictures weren't a priority when the engine was prepared. It seems to work fine. Of course, it takes much longer than 1000 miles to test a girdle.
The end caps 1 and 5 are very strong as they are fastened to the ends of the block where there is massive amounts of material and the girdle bars tie the whole lot together.
The best way of course is to do the complete girdle with the cross bolts and anchor everything along the way.
This simple tie bar is still a very worthwhile addition to any 6.5.
One thing that is absolutely a step in the right direction is to lightly chamfer the bolt holes in the block on all the mains especially the center ones.
The ragged sharp edges in the block are a perfect send off to getting cracks started down the outer bolt holes..
All really great stuff in this thread. Good tech and a step in the right direction.

In all the pictures posted in the thread (oil in the coolant) all the cracks seen to follow corners in the machine work ie. the piston bore. Robin is rigth that a sharp corner will not stand the pressure of a radius corner. The stress is spread over a larger area. All we can do is try to lessen the damage by rounding and bracing. Blazin has some personal value due to time spent with my son. So it is worth it to me to try.:) Question: Is the pattern on the mains the same on a 6.2l and a 6.5l?
I would really like to have more information about the roller rockers shown
Which parts were used?
What machine work do I have to do?
Anyone know where to get this info??
Jesel roller rockers were used. The original mounts on the head need to be machined flat to accept the Jesel rocker bases.
The valve covers need to be modified to accept the increased height of the rocker adjusters - or do as Andrew did, and machine a 1/4" aluminum spacer to raise the covers (fits between the covers and the heads).
Jim
Thanks for the info, but more specific which Jesel rockers?
Yes , to machine an aluminium spacer would defenetly be the way to go.
Would it be possible to get in touch with Andrew?
Sorry to be bugging you about this but....
I had a look at the Jesel web page and couldn't find any rockers that looked like the ones used so I asked Jesels tech help to identify them. Answer is that this is not a Jesel rocker setup.
What could it be??
Working from memory sometimes isn't always "completely" accurate. My mistake. So....Here's a quote from Andrew's original article he wrote in 2002... Jim
Quote:
The stock rocker arm pedestals were machined flat to accept the roller-rocker adapter blocks. The roller-rocker assemblies consist of Comp Cams adjustable stainless steel shaft-mount roller-rocker arms that have been modified for the 6.5 diesel. These assemblies utilize a roller bearing on the fulcrum of each rocker, along with roller tips. Each rocker shaft is .625" in diameter and case hardened to 62C Rockwell. The pushrod adjusters are made by Jesel, and retain the stock 6.5 pushrods.
OK
Thanks a lot
The girdle is still there and seems ok. This engine seems quieter but I never heard it before it was put into [I]Blazin[I], we are probably around 3000 miles and have done some towing with it. It is driven almost every day but normally not far my son uses it to go to school. I'll need to locate my drawing and get back with you.
That would be great :D :D :D
im looking for a girdle also
Hi 82blazer are your the girdles still in use in running trucks? Have you had the opportunity to open up a motor with the girdle installed? It's been a couple of years now and we would like to know the results after the motor was running with the bottom end strengthened up. Thank for the posts.:)
Still hoping to have girdle updates, anyone.....:(
Anyway, heres pics of our first on a 6.5L tdi....:D
No, sorry no pics yet, I need to first reduce their size to upload...:)
