My CJ7 is having fits on me!

My CJ7 is having a bad week.... I have been neglecting it. Grrrr....

My wife and I had a chance to get away last weekend so I figured I would
put a new air filter in it and a gas filter while I was there. It also
was acting like a bad distributor cap when it was wet out so I got a cap
and rotor too.

I open it up to get going and see my rad has broken again. The side
rail snapped off roading stretching the tubes out and splitting some so
I bolted it back together and soldered up the splits. It must have
snapped again last trip and was leaking slightly in the bottom corner.
This is at 5 PM on Friday so I just went and got some Gunk stop leak and
made sure I had the soldering gear on board which I did and plastic snap
tied the rad frame back solid. I also got extra coolant and pre mixed
it.

So I put the new filters in and change the cap noting the old cap still
looks new, but.... there is this crack on the inside of the coil wire
tower letting spark out sideways off the rotor post. Ok, that has the
wet start issues fixed and the hesitation/drinking gas from a plugged
air filter and half done gas filter.

I open up the rad cap to put the stop leak in and start to let it warm
up again and it is just sputtering and going on so I figure I got a wire
wrong. Turn it off, smell gas and see gas coming out of every crack in
the carb and pouring out the throttle shaft. Say what? Crap, the float
or needle is stuck so I take a rubber mallet to the carb and it mellows
out....

So now as I watch after I start it back up with the rad cap off and the
coolant rises and flows backward..... I shake my head and look really
close at the pump to make sure I don't have the wrong one in there or
something. I have been having odd overheating issues ever since I put
that pump in 5 years ago.

Well it finally starts to flow a 'little' in the right direction if I
rev it up pretty good so I poured the stop leak in and let it run a
while. Should have kept it at high revs it seems.

Then we pack up and leave at about 1:00 AM Sat morning after my wife got
off work and for sure 1/2 hour into this trip we lose the freakin' heat
totally and the temp gauge starts climbing. I figure crap the stop leak
didn't work so it has leaked out on us. Along comes a Husky so I pull
off expecting an explosion when I shut the key off. Stop, open the hood
and the hoses are hard with the heater core hoses ice cold....

Ya, ya, stop leak I know, but crap 'all' the heat?

I wait a couple minutes and crack the rad cap expecting a steam blast
and only get a short burp of air, no boil or anything. It is still
full.....

I run it again and again only have flow above 3000 rpm with the cap off.

So we put on the warm winter clothes (this is the first winter with
'real' heat because I got the hard top and hard doors on this body for
the first time so we are used to driving cold. Don't like it, but 'we'
can do it ok, my wife is a Jeeper big time) and kept on going north to
the bush with no freakin' heat. It was -25C. If I dropped to 3rd and
stayed at 55 mph I had some 'warm' coming out of the vents and the
temperature gauge would drop to medium instead of hovering just below
overheat.... We still could see our breath in clouds....

I think my waterpump impeller is slipping sometimes on the shaft. This
engine has overheated at the oddest of times and lately it gets too hot
over 70 mph for extended periods.

So by the time we got there the top heater hose had some heat and the
lower was luke warm due to no flow so the stop leak stuck there.

We were going to a relative's Cottage and the local handyman had the
heat on and the outdoor hot tub waiting at 102 F. It was nice......

So we started back, it was at the top of the H for about 20 miles and I
pulled into a gas station and still no explosion although the hoses were
really hot and hard.

I got gas and started it back up and it dropped to normal, I got half
heat and it only hit H twice on the trip with a gear down high rpm shot
seeming to make it pump again. Counter right?, overheating is usually
cured by low rpm...

Carb float crapped out again today....

It's a Jeep eh, it has a warped sense of humor some days...
