    So I'm about to send off a new old stock HO cam to Crane cams for a regrind. I was looking over the cam and something stuck me as odd about the cam.
    The cam rattles like something is inside it and after looking over the cam I found many holes in it for what I believe are oil passages.

    Are the cams for the first gen escorts hollow? And is there suppose to be something inside them that moves around? My guess its something to do with the oil passage holes. Or maybe its just a bad cam?

    I'm not all to bright on cams, more so cams for such a new motor so I have to ask.

    They're hollow for oiling just like the crankshaft

    Not sure what's loose inside yours, sounds scary....
    On the distributor end there is usually a worm screw or a cap pressed in like the frost plugs on the block. Double check there's still something there.
    On the pulley side the cam sprocket bolt is what seals that side.

    It's a plastic stick thingy that takes up space so that the oil doesn't take so long to fill up the camshaft tube on start up. It actually has a Ford part number.

    Surprisingly, I found a few of them for sale at Green Sales (NOS parts suppliers). As if someone would ever need one.

    I thought it was something to do with the oil passages. But it sounds more like a metal piece inside it.
    Either way it doesn't move much inside it and one end looks to have a worm screw on it.

    Joey do you have a picture of that tube? None of my 1st gen CVHs seem to have one in there - or at least nothing's loose in them to make me think there is

    The camshaft I took the part out of was a second generation, 1991 or '92, so maybe the part is different in the first generation cars.

    I took a look for it with no luck. Ford calls it a "Camshaft Oil Flow Control Rod", part number F1CZ-6B273-A, indicating a 1991 model year introduction.

    I couldn't find the part in my junk, as it's probably been ten years since I looked at it. I may have discarded it, like the damaged camshaft I took it from. I keep way too much old junk, but I figured the old damaged camshaft was really not worth hanging on to.
    Then I became interested in using an early HO camshaft in my '92, which doesn't have the lobe to trigger the camshaft sensor. Of course there was a perfectly good lobe on that camshaft that had no value, and therefore was discarded.

    I guess I need to never throw anything out, ever!
    Here's a link to the funny rod:

    Austin, is there any chance that Crane could measure up your cam and then you post the stock specs before they grind it?

    As EXPert has posted, there's a lot of uncertainty about what the stock specs are.

    I finally have a camshaft with one of those tubes rattling in it

    My 1.9 SEFI has it (and it is heavy judging by the sound and feel)

    Literally all my other CVH cams (all 1st gens) Don't have anything loose in them so either it's a 1.9 only thing or they're in all/most of them and just aren't loose for whatever reason

    Not all my 1.9l cams rattle. Maybe the plug just gets loose?

    I imagine that the rod doesn't rattle much when it is completely immersed in circulating oil in a running engine.
