Head gasket will cause white smoke out the tail pipe, plugged fuel filter, absolutely a possibility, try to blow through a brand new filter and then one that has been in a vehicle for 80,000 km, you'll have an anurism before you are able to blow through the used one.
That's why there's a filter in the vehicle, if it never got plugged, there would be no need for one.
In GM vehicles, a plugged filter change was usually the cause of the fuel pump packing er in shortly there after, have seen it dozens of times.
Had a gm truck 89k 2500 that could hardly make it up a hill without the throttle being floored and even then, brought it in, changed the filter and voila, back to full power.

it'll smoke if the broke gasket is leaking into the head...if it's leaking out of the head there will be a loss of compression and loss of fluid.
It smokes because it's burning coolant. So if it's not burning coolant, it won't smoke, but will still loose fluid and power.
Also, if it wasn't loosing power before the cooling problem, then chances are it's not the fuel filter.
I got my cavalier at 140,000Km and it's now got 210,000 and I've never changed the fuel filter, and never lost any power.
But what would I know I've only been woking on cars for 12 years.

Oh yea, don't let yer tank get to E and you won't have problems....especially with a used vehicle because you don't know what's in the bottom of the tank.
I thought that was a given, everybody should know that.

I have seen many head gasket leaks into the coolant passage (thus white smoke), and an external coolant head gasket leak, but very rare just a compression leak or both at the same time as the coolant passages surround the cylinders, not that it can't happen, but as I said, rare. The weakest point is around the metal band surrounding the top of the cylinder and the coolant passage right next to it. 99% of the time that's the problem. I have seen cracks in heads, causing coolant loss, overheating and white smoke, and then very rare the block near the head at the top, but it can happen.
have been an automotive tech for almost 20 years.
ps: wasn't trying to get into a tizzy or offend, just giving a fellow audio enthusiast some possibilities and advice as to what it may be based on my personal experience. Some repair facilities are less than honest, so a heads up is always a good thing, IMO.
and once again, very difficult to diagnose anything not in front of you, so best guess... right

My head was cracked on my car recently and the symptoms were loss of coolant and the cooling system would pressurize, then heat gauge would go to high.
I could let the pressure off by opening the expansion resovoir and drive another three hours or so before the heat gauge would go abnormally high again.
It turns out there were three cracks around one of the exhaust valves and the exhaust gas was pressurizing the cooling system
There was no white smoke on my car when this was happening, so i thought i was safe then 1200 bucks later....

I've actually seen it a few times myself, that's why I mentioned it.
Also, I can't remember but I don't think he ever mentioned white smoke or coolant coming from the exhaust, therefore I just assumed that he didn't know, that's why I said to check it.
Sure would be nice to have the vehicle here to see though, pretty hard, like you said, to diagnose a problem without the vehicle present.
Aren't those 6 banger jeep motors notorious for head gaskets? I personnally try to stay away from Jeep, they are a pain in the ***.

So...after driving for a few days....things actually do seem better - temps are normal, pretty well never get above half (which i think is labelled as 100). Granted i haven't done any distantce highway driving, i do have a short spurt where i get up to about 130 for maybe 5 or 10 minutes.
Could be wishful thinking and it most likely is, but the engine does seem to have a little more go (it was cooler this morning...could also be it). Even stranger, the engine seemed to rev down faster, meaning that if i was driving "at a faster pace" I wasn't being so hard on the tranny.
All in all, i'm fairly happy again, and will likely not go off road into some intense mud for a good while (that lil stint has now cost me about $1000 (some of which may have been considered regular maintenance, but even that i think came earlier than it otherwise shoudl have).

lol,
new radiator cap
new thermostat
remove radiator - gave a throrough cleaning
flush system
pressure test coolant system
they also, checked over the exhaust, all fairly new (within a year) upgraded to a larger pipe than stock and checked fuel pressure
