my problem? you can hear a very slight tick, like, if you pay attention really hard you can hear it. but only when the engine is cold. the guy said that my head gasket was going and antifreeze was leaking into the oil and oil into the coolant. he said the tick was coolant freezing in the cam where oil should be. i think its a lifter sticking. i need to change my oil soon, so its getting kinda sticky.
