i know my numbers are not normal, but at 7000 feet above sea level where the atmosphere is only 11.2 psi where at sea level its 14.7psi, the math would make sense wouldn't it? and it seems like i'm having the problems under boost as well, and the pressure test on the cooling system remained at 20psi when we did the test... i guess i'll have to assume i blew a gasket then.. but how would blowing an intake gasket cause such significant problems? just curious on that one (by no means am i questioning your knowledge, just want to learn more about it)

because once pressure inside the cooling system reaches 16 psi the cap pops off excess pressure and releases it into the overflow, a liquid once heated expands, hence coolant overflows into bottle, your methood of testing for blown head gaskets is not always a proven methood for revealing the truth, block check kit will test for hydrocarbons in coolant = next test you should do.

Thermostate, this time put it in correctly. BTW 90-100 compression is good if you have 7 to 1 pistons.

that was a really bad judgement considering i had the thermostat in for over 4 months before it did this and still continued to do this after i removed it... it had nothing to do with the thermostat.

This is a very dumb comment! before you get pissy please explain how psi converts to a certain c/r and how a piston is any certain c/r! You are showing your ignorance with this blah blah attempt at an insult!

OP you have your answers and explinations, your coolant system will reach 16lbs normally about 240* plus a leaky intake or head gasket could allow boost pressure to enter the coolant system!

the gasket might not be completely blown could just be seeping and then under boost casue your problem!

you were exactly correct, it wasn't completely gone but the material was missing between the water passages and the cylinder, took care of all of it in a parking lot and took extra time to make sure everything was clean and she seems to be running great, i'm not doing much until i change the oil, but thanks!
