Thanks. A little update on the process. I drained the oil and saw what looks like reddish oil. Looks like the oil is mixing with coolant. I always thought it would come out milkish but that might just be when mixed with green coolant. Another question by the way. What is th failure rate on cracked heads or cracked blocks. I dont have the money to go to a machine shop so i was wondering what i could do to test it at home. If it is warped then i will loan money to resurface. If anybody knows any good shops in sac let me know.

if the motor has not been overheated then your heads will probly be ok. would be a bummer to not have them checked and do the job to find out they are warped so the head gasket would blow again in short order.

I am not sure what you are showing? the part of the gasket that is stuck? or what looks like an o-ring on its last leg. What you are showing is what i would expect to see on an orginal intake gasket that old.
I am not sure what the reddish looking oil is but anti-freeze and oil always looks like a milk shake and the milk shake goo will be al over the inside of the valve covers.

thats not oil, it is old gasket that needs to be cleaned. The o rings where BAD they had cracks and peices missing. That part of the gasket looked like it overheated real bad. The oil is from my hands

So i dint pressure test. 208k miles with original head gasket ima replace it while i have time even if its good right now. I know that gm coolant is notorious for "disappearing" and with no visible leaks and a high rate of intake manifold gasket failure im just going to replace it either way. So i took off all the accesories, left valve cover but i cant get the last bolt under the engine lift bracket. I'm stuck for now. Any help? Also im thinking of running my car without a thermostat. I have remote start so i dont mind letting my car warm up in the winter. Old mechanics say get rid of thermostats as soon as you get the car. New mechanics call them idiots. Any idea on what will happen if i run without it?

removing the thermostat can cause the motor to run hot or overheat, coolant does not have time in the radiator to cool and the coolant runing though the motor faster gives less time for heat transfer there as well.
