O rings

Mine are the most I've heard of: Stainless .051 wire with 18 thousands protrusion.

The one's in all the local trucks here are .035 stainless rings with .011 protrusion. Have had good luck with them.

I just did one with .041 stainless wire .012 pertrusion. Seems to hold 85psi just fine
 
Jefferson State Diesel just cut my o-rings and it is holding great
 
So all I have to do is give those specifications to the machinist and they can do the rest, or should I have the rings already handy and give them to the machinist?
 
hey jim do you run into problems with the HG not sealing up the water and oil ports with that much protrusion
 
I ran that setup since the spring of 03' with zero head gasket issues, I have run it with both 12 and 14 mm's all it requires is a little more attention on the initial T/Q set, call it one more head cycle/retorque.

My thinking now is that either wire .041 or .051 with at least 10-12 thou should be fine as long as you have a flat head. Mine was cut like I said way back when. Also I have run that with both .010 over and .020 gaskets.

Yeah... that's wright about the copper HG!!! :hehe: How bout a reciever grove? When i build gassers with o-ring's, i cut grove's in the block and head. That way it lock's the top and bottom of the HG. Kinda like a toung and grove type thing!?!?!? Didn't know if anyone was doing this or not.
 
I have used 041 ss wire, 041 Inconel wire and 051 ss wire.
The Inconel is so much easier to work with. I Like to end up around .010-.012.
 
I'm working as an aircraft engineer and the wire that you are talking about look's like SS or INCONEL aviation lock wire' is that right ???
