Hello all, decided to reseal the head on the d6, got all the parts together including some "super 300 permatex", was wondering if the ferrule direction in the block made any difference, noticed that one side is tapered almost as if it was made to jamb in one side or the other; any thoughts on this?

I never asked why they were that way. I just put the blunt end in the block and the tapered end up. I figured the block was stationary and the head varied/wiggled a little as you set it on the block and the taper was to compensate for that.

Install with the ferrule rolled edge towards the head.

Don't forget to check cylinder sleeve projection.

ok, just wasn't sure and am trying to do everything right this time around, even bought a new core from costex( very happy with quality by the way) compared to the prevous one from general radiator that broke after 100 hrs. caused me to overheat and blow the headgasket.😞crossing my fingers that the head is ok.

Forgive my ignorance,but what would i do about the sleeve projection, when i originally replaced the liner rings, if i remember right i just bottomed them out and figured that the tourque would do the rest am i wrong?

Anti-sieze the prechamber threads and use a light amount of o ring lube on the ferrules. Use some permatex around the right side of the head on the block and head where the pushrods come through. I assume you have all the torque specs also?

Was just about to research the tourque specs; read alot of old posts today on sealers and the consensus seemed to be that the # 2 permatex formulation had changed and the next best thing or better was the #300. which remains pliable. Just use it around the outside edge though?

The liners on these aren't too critical but you could check them with a mag based dail indicator, they should be within .004"-.006" in four spots around the liner. if im correct Ole Mag can correct me if not lol

Mainly around where the pushrods come through, they always weeped oil around that area. I don't have my service manual handy but the other members on here will have the torque procedure and torques I do know the chambers are tightened to 200ft lbs.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
