Lightbulb Rocker Arm Assembly (Discussion)

Well was one big step for EF_GuY yesterday. First time i've pulled apart the rocker gear on falcons.

I decided on this easter break to findout myself whats causing the slight tap tap tap in my engine. I'm now 90% sure what the problem is and getting parts on tuesday.

I found out that the EF rocker assembly uses thrust washers between the rocker pedestals to space them out as well as wave washers.

Whats weird is teh EA-EB1's and EL's use the rocker assembly without the trust washer.Seems the pedestals are made abit bigger 1-2mm to make up the difference.

What i found out on mine is the trust washers have worn the grove in pedestal to the point that the washer has movement thus making the rocker move slightly as well.
So mechanically the car runs A1 but becuase these trust washers are loose they make a taping metalic noise.

I think thats the reason why on the EL's they went back to the trustless washer assy as it's a much more robust design.
Perhaps the trust washer design was put in the EF because they run a more aggressive cam than the EL's. I've always noted that EF's have a slightly rougher idle than EL's.

Anyways i'm probably boring everyone here but just thought i'd like to share my experience.

Corrrrrr. Sounds like you have had more experience with Ford I6 Rockers, Valves, shims, Lifters, etc, etc, in the past month, than an average mechanic would have in an entire life time !!!!

Good to hear that you found the problem !
Even better to hear that you found it out yourself !!!

Congratulations on your good work !!

Cheers
Matt

Hope your diagnosis of the problem turns out to be correct although I have my doubts that a worn thrust washer or pedestal would cause a noise as you describe. Have you checked the valve clearance between the rocker arm roller and the camshaft lobe?
