    I suggested going to the junkyard, pulling the crank sprocket and cam sprocket off of any japanese car with an overhead cam, find out what make and model it is, buy a new timing belt and tensioner and fab up your distributor, those sprockets are precision made to work on a cogged belt and stay in perfect time to drive the cam at half engine speed,which is what you want. you need to rig the distributor with some sort of pillow block mechanism, and find a way to connect the cam sprocket to drive it,and the crank sprocket to be driven off of the crankshaft.

    The 1.6L Escort distributor has bronze bushings and no oil supply - at least nothing like you get in a SBC. There's oil and oil mist in the area on the engine side but no pressure running trough it. Mine had grease in it and was a little worn - muct have been slightly misaligned with the cam from the factory.

    I think the key is to set it up so the distributor bushing not supporting the belt tension.

    I can't seem to find a 1.6L distributor online that has a photo of it.
    Heres what I've found

    i want to do this also, to this exact same engine. Not for whim reasons, but for practicality reasons. So let's continue.

    (Also note: The 2.2 does not have a provision for a conventional distributor. Also, i don't think there is a provision for a mechanical fuel pump.

    1) Tell me all you know about gilmer belts/gear belts, 8mm belts. Mainly, i'm concerned about durability/reliability for a daily driver.

    2) Could a hole be cut into the timing cover (i don't think the water pump on a 2.2 is in the way) such that the distributor's shaft base(the part taht turns, not the housing base) could be solidly attached to the cam gear end-to end? The timing cover would then be sealed around this hole so no oil would leak out and then the timing gears and chain still gets lubrication normally?
    In this way, we eliminate the need for a belt---and the alignment and extra fabrication issues.

    2a) Could a rotary style fuel pump be attached directly to the crank pulley, end-to-end as in the above example? Again, this eliminates the need use a belt, extra fabrication and alignment issues.

    I think the 2.2 does have some sort of provision to mount a distributor.
    I could've sworn I saw a 2.2 motot with a home built sheetmetal intake, a 2 barrel and a distributor. I'll try to dig it up.

    I have another truck now, and I've got the motor out and I'm currently rebuilding it. there is a spot that looks like where a distributor would mount. It just has a little metal cover bolted onto it, and I can see a gear on the crank.

    The 2.2 is based on the old 2.0 the sunbirds and crap had, and those had distributors.

    Here are those photos.




    "we have a distributor from a 84 cav, well 2 actually both are cut in half and welded togather to lengthen them to clear the intkae. and we have a home made custom built intake to hold weber and holley style carbs"

    I used cam and crank pullys from a Lotus 907 to drive my oil pump and fuel pump. Because I had them. Most all timing belts I looked at were 3/8 pitch. Fiat-Pinto-Nissan and Lotus. Belts in many lenths are readely available from Daton or Gates. It's all standard stuff.

    Any luck with this setup yet. I have the same motor with the same problems.

    If you really want a carb it would be way easier to swap to a 4.3

    Previous post was 10 years ago. He's probably shitcanned the whole deal by now.
