2001 XJ 4.0L Oil Pump Failure. WTF?
The Jeep: 48000mi 2001 Cherokee Sport, 4.0L Auto.
The Incident: Driving along, suddenly there's engine light,
followed by check guages light, accompanied by ticking
from top end and no oil pressure reading on the guage.
I shut it off and cruise to a good pull-off spot. Pop the hood,
check the oil, plenty there and not too bad looking either.
The Most Obvious Diagnosis: Oil Pump Died.
Anybody here experienced this or heard about it? It just
seems odd that the usually indestructible 4.0L in one of
it's latest and finest forms would take a dump this early
in it's service life. I've had others that are still running around
at 160k+, hence I bought another one with low miles with
the intention of driving it for a long time.
I'm headed to the alldata site to see if there's a TSB...

Wow, I see I've been away for awhile. No free lists
anymore and redirects to Autozone for parts...
No oil pressure TSBs for WJs of the same vintage...
Hmmmm....

Hi Matt,
Nope, never heard of it, only when the distributor shaft seizes and
breaks the drive gear, which of coarse kills the engine, or drive rod on
other types of engines. Pull the distributor and you can find something
broken. Then use a large screwdriver bit on a drill and spin the pump
and see what happens. Been a little lax on the oil changes lately?

Hi Matt,
I think they always directed you to place that asked for money to
further defined the recall: http://alldata.com/TSB/04/010433d2.html The
1926 Nash engine is pretty well refined by the time you bought it:
