Re: 1996 Cherokee 4.0 I6 timing mark. ??
But as there are helical gears on the bottom you have to off-set the rotor
when you first guide it in. To get proper placement may take a couple trys
to get it into the right combination of teeth so the rotor is pointing
exactly at the number one terminal..

The trailing edge of the rotor should be just PAST the #1 terminal at
TDC.

The trailing edge of the rotor should be just PAST the #1 terminal at
TDC.

If it was there, we (3 of us) never found it.
Anyway, it was a no-brainer.
The A/C compressor was in the way on #1 so I timed it off of
#6 plug hole and #6 tower on the opposite side of the distributor. Got
#6 on the compression stroke by the "thumb in the hole" method then
ran a screwdriver down the plug hole and could feel the piston
movement when the crank was being turned with a socket (not the
starter!!!). Got #6 as close to DTC as possible by feeling the piston
stop at top . Set the rotor button to where the trail edge had just
cleared the #6 tower and locked it down.
Presto. It ran like a Jeep! :)
Took about 20 minutes and I now have an extra case of beer-- and a
happy neighbor.
A great big old Thank you to all who responded.

Thanks for the follow up!
You and your 2 friends are correct about there being no timing mark on
the 4.0 engines. I own 2 4.0's.
I just saw --------'s photo over on alt.binaries.pictures.autos.4x4 and
it is -------- just like his posting name. He has shown a photo of what
appears to be a 4.2 engine with it's V-belt pulleys and timing mark.
He is a hard person to follow, sometimes his advise is right on, other
times it is complete --------.
The 4.0 does not have adjustable timing, the distributor fits a notch so
there is no need for anything above a TDC mark.
