need help with overheating 88 100q

[Hoffman Anthony J A1C 552 CMS/MXMVC]

There are three thing that go through the headgasket. They are compression,
oil, and coolant. Any number of combinations is possible. In your case, it
sounds like the compression is going into the coolant. An easy check is with
a coolant system presure tester. Screw it onto the top of the expansion
tank, and start the engine. If the pressure goes up right away, you have a
bad headgasket. It should take about 5 minutes for the pressure to go to
that level on a properly running car. 

If the pressure level goes over 20(or starts leaking before), the
compression has probably blown something in your cooling system as well.
Keep in mind, a cooling system is designed to hold about 15 psi, while
engine compression usually excedes 100 psi. Something's got to give.

Hi,

I have been driving a friends 88/89 100q for the past few days, thinking 
about possibly buying it for g/f as daily driver.   The car is in very good 
condition, everything works...  etc...

I was driving in downtown Portland traffic stop and go essentially....
after 
about 15 minutes I noticed that there was steam coming from under the hood.

The temp gauge on the dash was only registering about half  and the fan was 
cycling on and off.  when I was able to pull over I lifted the hood and
could 
hear water spraying somewhere by the bottom corner of the radiator by the 
engine but I couldn't see the  water coming out...  It sounds like the water
pump 
went bad but it doesn't sound horrible.  It looks like the hoses are intact
but 
the radiator appears to have seam seep, and the overflow bottle was empty.

I also noticed that there was water coming out of the tail pipe but it
wasn't 
really steaming and the oil appeared free from water...    Also the car has 
had a harder time with starting lately, it usually sputters and dies on the 
first try and the runs fine on the second try if it is given a little
throttle..

I guess my question is how likely is it that that headgasket is also 
blown?...   Has anyone gone through anything similar??

Thanks for any help
