Outer Limits 4x4 Board

Hey all well i noticed yesterday, when the motor is warm and running i have bubbles comming out of the head gasket on the intake side of number 6 cylinder, i dont know if it is water or oil, i looks like oil but i thought if the head gasket was on its way out it would be water.

Oh so confused!!! i go to fraser next saturday, whats the going rate to get a head gasket changed???

What are peoples thoughts???

Where the arrows are, they are little bubbles that the camera couldnt really pick up properly with the lack of light and heaps of zoom.

if there is no water in the oil or vice versa, and compression is good, id put a bottle of chemi weld in the water and see if it stops, if not then its probably oil. head gasket about 100-200 for the gasket (depending on car and supplier) and about 1k of labor maybe a little more.

Its a 1hd-t 80 series cruiser. that was sort of the price range i was expecting. what causes a head gasket to go?
