...detail and show pic if you can? i need to see pics/video showing how its done and location of the part and how to do it right.

tgo to the supra forum there are instructions there for the 7mgte very similar engine

well you put this ? in the wrong place but i think you need to take it to a shop cuz when you replce the head gasket on some cars you need to get the head machine and the bolts go in a certain pattern so i really suggets you take it to a shop it is going to cost you some cash probably around 5 to 8 hundred maybe more but make sure that it is the head gasket and not a crack on the head or it will cost you alot more and if it is a crack your better off replacing it instead of having them well the crack cuz it will break again i tell you this out of personal experiance good luck
