    Gear looks fine.  you need to check the advance springs, pegs, slots, points pivot, contacts.

    A good friend sent me a replacement OEM harmonic balancer and unfortunately it broke in shipping.  However, I compared the one I took off and the one sent, 13.2lbs vs OEM at 12.2lbs.  One can definitely see an overall size difference as well.  My questions;  1) are the engines internally balanced?  I believe they are but I’m not 100% sure.  2) would the weight difference of the harmonic balancer effect the engine? 3) does anyone other than Wildrick’s sell the btonze cam thrust washer?  I’ve called multiple times & can’t get the basic question answered, “does the cam thrust washer fit both the 6 cylinder as well as the 8 cylinder?

    Yes, thrust washer fits all models. I would use the original dampener.  All Hudson engines were dynamically balanced.

    You can think of the splasher 6 and 8 as pretty much the same engine with different numbers of cylinders. Going forward from the front of the block everything is interchangeable, front plate, timing gears & cover, thrust washer, pulley, pulley spacer.

    I need to locate the bushing / sleeve that the timing cover seal rides on anyone know where I can find it or can I just flip mine backwards?  How much play should there be With this sleeve against the crank?  I’m a little worried it maybe worn too much on the inside to flip it.

    It is held firmly in place by the crank dog, so just turn it round to get extra life.  otherwise buy a new one from Dale Cooper.

    Try and use sealant to stop any oil or water leaks where bolts go thru anywhere on the motor/gearbox/diff. Its been a long journey for you with all the repairs but the enjoyment at the end will be worth it. Also others have also learnt a lot because of your pain :)

    So as I looked at the cam head I was wondering how much, if any, I could move the cam forward with just a small prying of the head against the block?  Now the distributor & oil pump are still in place & not removed as are all the valves, springs & lifters.  

    So I very gently pry’d and with only very gentle pressure, like a pound was all, the cam head moved forward a lot!  I slipped a 1/8” thick washer behind the head with room to spare.  So is the cam supposed to be able to do this?  Is this a sign of some kinda problem which needs fixing?  Once the cam thrust washer is in place (& everything back together) at only 1/16” thick, what is going to keep the cam from pushing forward & bounce forward & back in the 1/16+” of space I’ve just found?

    The peg that is sitting in  the nose of the cam should have a strong spring behind it, and the peg bears on a thrust pad on the timing cover.   The angle of the gears ensures that the cam will be forced back against the  thrust washer during use.
