Re: Dead Jeep
I found the problem. I just am wondering now how it happened.
I had some friends stop by and they were turning the key while I had the
distributor cap off. The rotor was not turning over at the same speed at the
starter, it would skip a beat every so often. We removed the distributor and
looked down the hole while someone was bumping the starter. There seems to
be a few teeth missing off the distributor drive gear on the cam. The gear
on the cam didn't seem loose, but I will be able to see it better once the
timing chain cover is off.
If anyone has a clue as to why this would happen, I would be glad to hear
from you.
Thanks to all.

The only thing that can hold the rotor back with any force is the oil pump
but then there is a 70psi bypass. I've had the rotor tick against the cap
before but that was due to a worn bushing.
It could be due to a defect in the cam or distributor gear, but even then
it's not something I've ever seen. (not counting engine bits being sucked
into the oil system after shredding a main bearing.) >_<
At any rate your looking at quite a bit of work to fix that problem.
(yes, the cam can be pulled from the front without dropping the pan but
with missing teeth your time ahead to drop the pan to check everything.)
I'd probably do it again, but rotate the engine via the damper bolt.
Just so you can get a better look at the teeth on that cam.

Re: Dead Jeep
Hi James,
The oil pump by-pass was smashed and jammed by the differential
housing. You need a new timing chain cover:

to keep from breaking the distributor, oil pump drive gears:

Thanks for the links Bill.
The guys at IFSJA gave me these links:
http://www.froadin.com/forum/phpBB2/viewtopic.php?t=34
http://www.bulltear.com/forum/viewtopic.php?t=2039
http://cgi.amcforum.net/cgi-bin/yabb...num=1089730100
I had no idea this was a common problem. In addition to that, if I don't fix
the cause of the problem it will keep on happening.
Unreal.... I need to do some reading before I tear into it.
Thanks all.
