    Guessing its as simple as getting the #1 plug in the right spot....There are are even fire vs odd fire distributors, its not just a difference in the cap. It has to do with the cam lobes/flats on the distributor for a traditional points set-up....although when it comes to HEI, maybe that doesn't matter?

    Different pickup coil in the distributor for OF and EF engines.

    I will look into that, but I think we had the coil/cap thing figured out.

    I also remember changing some sort of a module in the distributor itself.

    I'll just start over again using all the odd fired parts, and see what happens.

    One more question, and I'll quit for now. lol

    If I'm standing on the drivers side looking at my HEI distributor, with the tach wire connection at the 1 o'clock position, where on the cap would your number one plug wire be attached?

    Here's something I find kind of interesting.
    I have 2, 1967 225 v6s, 1 stuck, 1 unstuck.
    On the 1977 engine that's in my cj right now, there is a GM casted into the block where the casting numbers are.
    On the 2, 1967 blocks there is no GM casted into the block. Hmmm

    I would think that's because jeep (kaiser) owned the tooling in 1967, but in after AMC bought jeep, they sold the tooling back to GM in the early 70s.

    Buick motors are notorious for low oil pressure and flat cams. Very common for just one or two lobes to wear down and cause many different issues.

    Don't give up though! When you do get it right, you will drive it and think, "This is the best engine ever manufactured for a Jeep, hands down." I owned AMC V8 Jeeps, AMC Inline 6 Jeeps, 4 bangers of Iron Duke and Willy's heritage, and this Oddfire V-6 is the best engine they ever put in a Jeep. The next closest in my satisfaction level was in my 68 Gladiator plow truck that had a 350 Buick in it. Push a blade full of snow with a hopper of salt in the back and not care a bit.

    I had two lobes going out and the rest were fine. I guess I caught it in time because my oil pressure and compression are good. The grit produced will wreck your bearings. When I did my cam and lifters I cycled atf through mine with a drill motor and cleaned the pan afterwards then installed new parts. I noticed oil supply is not great to some of the rockers farthest from the gallies. I took the rockers apart, cleaned and check the clearances and that helped.

    As soon as the rain quits, I'll get back to it. lol
    Took my oil pan off out in the yard, I can't drive her in my shed right now, so I get to wait.

    There were a couple of tiny pcs of metal in the oil pan when I hit her with a magnet, but I figure they won't be going up the oil pump, so no problem. lol

    I haven't given up yet, not much left to replace. lol

    Important picture for HEI distributors: I don't have one blown up handy

    LEFT is Odd Fire - RIGHT is Even Fire


    Notice the uneven lobes on the OF pickup - also three points on the shaft.

    Even fire lobes are evenly spaced and Six Pickup lobes.

    Frankly - I would double check the cam based on everything your talking about. I've had mix and match motors in the past, and the '51 is a 225 OF with a 231 water pump on it, so timing marks are off. You have to know what your doing when you mix parts and some people are not that careful.

    Sun shining today, should get a chance to work on her again.

    Warloch:

    Another helpful pic, that should clear up another question.

    Thanks for all the info guy's, again very helpful, but I'm guessin I'll have more questions after today. lol

    Warloch gets an A++.
    Even fire distributor, in an odd fire engine.
    Thanks, I would have never figured that one out.

    Is there a way to convert the even fire to an odd fire?

    Checked with Rock auto, they are out of stock on oddfire distributors.

    Any other suggestions for a supplier.

    Maybe someone out there in Willys-World, has one they want to part with?
    I have a hardly used even fire setup that is more or less brand new, that I could trade. lol

    Now, I'm feelin like we might get her fixed yet. lol

    The bonus of all this is that this engine had an HEI originally.

    I had no idea they made an electronic (HEI) dist. for the oddfire. Something seems wrong. Hope I'm wrong so I can go buy one Lol. BTW, If you end up with a points unit, get a tach/dwell meter if you don't already have one.
