    Default Rocker Arm Cover Pad

    I am assembling a 1953 FL. There are two 'Rocker Arm Cover Pad', p/n 17507-48; rectangular felt pads with two slot.

    What is their purpose and how do I attach them to the heads?

    Thanks

    I think they just glue to the inside of the rocker covers, noise dampening?

    The felt might dampen some noise. Felt is also used in lathes, mills and other machinery to wick/drip a constant oil supply to certain parts.
    I have no idea how much oil is actually held in the Pan rocker area (that would be an interesting experiment ) but I don't think it would be much as the oil return hole is a good size and the oil is quite runny by the time it has done it's job up there.
    The felt would soak up oil that is splashed around by the valve spring caps and drip it onto the front and rear intake oiler tubes.

    Forgot to add this to my post...are the oiler tubes readily available?
    If the answer is Yes to aftermarket, do they fit and work correctly.
    I have a few sets of Pan heads in line for rejuvination.

    I experimented a while back with different glues. Glued per directions using felt and test aluminum pieces, then soaked in oil. I tried yellow 3M weatherstrip adhesive, Weldwood contact cement, Devcon all purpose adhesive, and Gorilla glue. The Gorilla glue worked best so I went with that. I also made a block with steps to match the cover so I would have even pressure across the whole felt, put a heavy piece of metal on top while glued tried. I have not put them in action yet, but glue has held well for a month now. Every cover I have taken off you can see the stud and nut impression in the felt so I don't think they move much.

    Steve, I bought some of the aftermarket oilers. I have not used them, but like most aftermarket they look pretty cheesy compared to original. I'll check later to see how they fit on the studs and let you know.

    Is there any documentation explaining the purpose of the pads?

    They hold oil and prevent valve covers from resonating.

    Gorilla Glue it is, thanks for the explanations and tip.

    Can I install the rear rocker cover in the frame or does it need to be installed on the bench?

    Any tips on the oiler tubes? I have what appear to be original equipment that direct oil over the rocker-arm valve stem interface.

    On the bench, it cannot be done in the frame.

    Just make sure they are clean. Intake only.
