Plug #3 out of a 2000 jeep cherokee 4.0L. The engine stopped running last night while towing a trailer. Check engine light came on blinking, sputtering started, ran very rough for about a mile, then died. Now I can't get it to turn over, even with the plugs removed. I have not tried to turn the crank manually, or back it up.
Plug looks like there is something loose in number 3, valve broke off or something. Anyway:
Worth trying to fix? What Do I do next?
Thanks for the help...

What do I do next? I plan to pull the oil pan as mentioned before, but what else?

Have a 1988 jeep Cherokee 6 cyl 4.0 4 wheel drive
I have a rear main seal leaking and need to replace it
i have been told that you can pull oil pan and go through there and change out seal without having to pull tranny
because the seal is a 2 piece
Was wondering if anyone had done this and could
share any info or suggest ens or warnings.
thanks in advance

UPDATE: here are pictures of what's under the valve cover.. I can't see anything too alarming, but I don't look under here often. Nothing is loose or appears to be broken, missing, etc. the ONLY alarming thing is that there appears to be coolant mixed in the oil.
What do I do next? I plan to pull the oil pan as mentioned before, but what else?

Since I have the valve cover off, i have not tried to crank the starter- for fear of causing more/possible damage.
There is some coolant in the oil-- one local shop thought possibly a torque bolt got loose somehow or something-
Or if coolant got into engine maybe there was some hydrolock of some kind...
I think there is something broken or bent - there has to be something to cause number #3 sparkplug tip to bend over like that..
So the engine isn't siezed technically, but it doesn't exactly "turn over"
