ok so me and my dad just put a new 2.4 twim cam into a 96 cavalier 5 spd. i took it for a test drive and bubbles were being blown into the coolant resivoir causing it to leak out the cap. so we took off the head and changed the gasket and cleaned it up a bit, and the same problem persists but after we put everything back together the engine started clicking like the lifters werent oiling or something.can anyone help me with my problem?

 

anything anyone?
