Ok guys, it's been a while so you may need to go back to page 1 of this post and look at my progress but I started looking at my car again this weekend. I rented a compression tester from autozone and tested all my cylinders. They all went up to 110 PSI and stayed there for 2 minutes no drop in pressure. This makes me thing there is no head gasket problem now... I am at a loss. Why am I still losing antifreeze via the overflow? Is there a way to test my radiator for functional problems? Is there something else I should test?
