Head Gasket testing methods
After taking my 4 Runner to the dealer for a missing problem, he said he needed to do a whole list of things and if that didn't clear it up he would have to change the head gaskets.
My question is: Is there any way to pinpoint a blown head gasket from the start?
Note: No sign of oil in the coolant and no sign of coolant in the oil.
Thanks, Bruce

I would think that a compression check would show the blown head gasket. A gasket blown between two cylinders would make both cyclinders down on comperession ( weak )
It is possible to blow a head gasket and yet keep the oil and water where it should be.
Just my two cents worth !

There is a very neat tool sold a most car part stores it is a dye that you put in a in the tool ( looks almost like a turkey baster ) ant with they radiator cap off you pull the hot gases out of the radiator into the tool (not coolant) and if the dye changes color you have a blown head gasket or cracked head. what changes the dyes color is when you have combustion gas in the coolant and thats not good
