Re: wrangler towed in gear
That is not a good thing...
Anyway the pump quitting sounds like it is a coincidence or maybe when
the head gasket blew, the water went low and the pump bearings burned
out would be my guess.
I would be pulling the plugs to see which one is really clean. This
clean one(s) will be the one with water in it.
A compression test is in order. Testers are cheap and it can tell you
if it is a toasted head gasket or worse the rings or a piston broken
too.
The head has to come off anyway by the sounds of it so doing a wet/dry
compression test can tell you about the rings usually. If the rings are
toast, the engine will need a rebuild

Re: wrangler towed in gear
Thanks Mike. We weren't really sure the head gasket had blown, after
finding out it was only the pump leaking. With the smoke though it
looks more likely. We have a service manual and i'll need to get a
compression tester and a tourque wrench. I've never pulled a head so
this should be interesting...

Re: wrangler towed in gear
Mike and John,
Here's what we found. We bought an Actron compression gauge and
checked the compression of each of the cylinders today:
#1 151 psi
#2 155 psi
#3 152 psi
#4 156 psi
We cranked the engine about 8 times per check and the meter would go
to the maximum reading after 2-3 revolutions.
We took pictures of the plugs and posted them here if you want to have
a look. I didn't see any oil today but on Sunday the #2 plug appeared
to have some oil on it:
http://public.webbox.com/680000/
As we tested I watched the other 3 open plug holes and didn't see
anything coming out.
What do you think of those readings?
