Rocker arm pivots

[mpowerdog]

It's been quite a while, & I'm finally getting back to it.  Pulled the Al cover bec of a noise that seemed ta be comin from there, removed a set of arms ta find off-white, 'delrin'/nylon? pivots.  Huh?  Seemed ta be a 'lot'? of back/forward movement, & I couldn't find any info about them, so, I figed someone here must know something about them.  Are they a noise reduction idea?  Replace them?  With metal?  Arms & pivots?

Thx

I never saw them on i forget how many 6es i ripped apart. Go a shop ask them what the h e ll. Maybe different push rods?
Post a pic of a cleaned one please. Thx

Ditto on what Mudkicker said.   I've never seen such a thing, and I've been messing with AMC's for decades.    I'd also like to see a pic!

I'll post a pic tmrow.  Even checked a jeep joint, & they never heard of.  Does it matter that the mtr has hyd lifters?  It appears ta be a stk, finned, Al cover.  No after mkt drilling. I'll also verify the yr on the title. Thx

hi, those may be the "umbrella" style valve stem seals. good luck, gz

Duh me.  No such things.  It was dark, & I hadn't wiped off the creamy condensated oil

Now, back ta gettin her runnin & find that noise that I didn't like.  Sounded like something knockin on the Al cover.  Took a bit ta get her started; new motorcraft, blew out the fuel line, new pump, filter, and got my new hei a few days ago, but not installed.  Gear conflict from what I read

Thx

hi, if you bought a decent HEI, as in from DUI or CRT, there should be no gear problem, good luck, gz

Swp ultra fire from skip white performance as a direct replacement, but will compare the gears before installing

Thx for the heads up

Well, started to close her up tstrdy, wrong gasket.  Was for plastic cover, & Al cover gasket @ CarQuest was $36.55, Felpro, 'rubber' encased metal.  Now that shouldn't leak
