My car is using a little coolant, getting bubbles out of the radiator only when I blip the throttle, and only smokes a little when it's warm. I did a compression test and all were the within 5lbs except #4 and it was about 7-9lbs lower than the rest. And there is no coolant in the oil yet (thankfully) So, would you say that is the Gasket leaking? And, since its stock injectors, would it have ran lean enough, and blown just 1 cylinder? Do you think the head will still be flat, or will it have warped it a little? Thanks a lot, Will
