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.

There he is, once again proudly displaying his ignorance!

That picture was the only one I could find, and it's not a 4.0L, but
it was meant to indicate loacation, and that's what it does. It may
not look exactly the same, and it's hard to see with the serpentine
belt in the way, but it is there whether YOU can see it or not.

>

Unlike you, I only post when I'm sure I'm right on. You need to go
take a closer look at your Jeeps. Maybe find a good mechanic to point
it out to you.

Or, ask DougW. He will tell you it's there.

The notch locks the housing in. It doesn't, however, insure that the
rotor will be pointing in the right direction. You need #1 at TDC to
install a distributor correctly. The OP found a way around it, but
the marks are there if you need them.

In fact, around 1988, they issued a TSB that dealt with a crossfire
condition caused by rotor misalignment. The fix was to use the timing
mark on to put #1 at TDC, then cut the notch off the distributor
housing so it could be rotated to properly align the rotor with the
terminal in the cap.

The mark is there, it always has been, and was still there on the last
4.0L used by Jeep.

Guys .. Hey... I believe you (sounds lke some threads in the Dodge
group .. :). After looking the situation over, I didn't need the
mark, anyway.

Bllsht's post:
"The trailing edge of the rotor should be just PAST the #1 terminal at
TDC."

That post saved the day for me. When I put it in the first time I
centered the tower and it ran like crap. I thought I remembered about
the trailing edge .. re-checked the posts.. and set it like Bllsht
said. That cleaned it right up.

Thanks Bllsht!! :)
