I posted this in the diesel section.
It’s a few questions about my 1986 HJ60.

I am replacing all of the gaskets/seals/o-rings in my exhaust system and just have 2 questions:

1: the o-rings that are to be installed in the two part exhaust manifold get placed under the snap rings in the grooves, correct? (I have new snap rings and o-rings).
When I popped it apart, there were no o-rings to be found, so my guess is that they were under those snap rings at one time.
Can somebody clue me in on that, please?

2. When I reassemble the two halves, should I use some kind of lube or anti seize to pop them back together smoothly? I read something about some copper anti seize, I think.
What have you guys used?

All of my studs and nuts appear to be in good condition. I figure I’ll just make sure they’re seated well in the block and start putting it all back together.
Any thoughts on reassembly?

Thank you guys in advance.

I dont know if the 2H is the same as the 2F...but the 2F has two sealing rings and two spring rings per exhaust piece. The spring rings go under each of the sealing rings and the sealing rings get wound into place much like how you install compression rings on a piston. (carefully).
