Return Caps Rev. 1.0
They've finally arrived...
Sorry about the poor quality Samsung P&S pics... The caps turned out quite well. Revision 1.0 is a material change to brass. After I showed him the last round of backyard TIG welding, my dad decided to change materials and silver solder them himself. I couldn't get the flux off with the non-abrasive scotch brite pads I have.

I was wondering what happen with the follow up. Nice proto-types. Do you have some Viton #111 o-rings (16) to try them out? They appear pretty thick in the wall, he could probable turn the O.D. down some to save bulkiness which may cause premature o-ring failure from vibration. Keep us updated and see if he's willing to make sets for resale after some testing.

Yep, 42 viton o-rings left for testing these.
The barbs sit inside a tight clearance hole and the solder runs in after heating creating an air/water tight seal. That's the reason for the thickness. I suppose he could've stepped it down a bit away from the barb holes.
I thought he was going to fin these like he did the aluminum, but he was in a hurry due to all the other work he has. He wants to know if they work or not. He's actually making another few aluminum ones and experimenting with brazing/soldering aluminum. If he can do it, he'll send me a complete set of aluminum caps too.

Success
Got them installed yesterday after doing the valve cover gaskets, retorquing the rocker bolts, installing new glowplugs & injectors.
No leaks so far. We used the average tolerance between all plastic caps. Installing these was a bit more difficult because they're not plastic and don't give at all when pushing them over the o-rings. So you don't get that snap, but they've been machined so when the fuel lines are tightened, the caps will seat properly. I actually gave them a few taps with a very small brass hammer. You're able to turn them by hand when they're installed. I have not measured their temperature since running them.
