my 95 4runner just started running (abnormally) hot when pulling hills. no evidence of leaking antifeeze, radiator is full, system was flushed and filled 4 months ago, i don't smell af on the dipstick... thought maybe tstat was sticking, but why only on steep climbs? i also sensed a noticable loss of power as the truck began to run hot..... any help would be great....

Head gaskets are there too make an air tight seal and keep the compression you build inside the piston chamber. If there is a leak in the gasket you will loose compression and overall power. Have you heard of people increasing the compression in their cars? Either by making modifications to the engine components or by forced induction (i.e. turbo, or supercharager) which forces more air into the piston chambers causing more compression and air pressure, which results in more power. So if you feel you are lossing power then you probably have a bad head gasket. Not always the case though.
And yeah, a compression test should be the easiest way to find out if your head gasket is bad or not. I believe you can buy a compression tester which hooks in where the spark plug goes. You have to get the piston to the bottom dead center and the proceed to have it go to TDC (top dead center) to get an accurate reading.

No, they don't always show up that way. I never use it unless it has a miss, If your car doesn't run right then do it, it could be blown between cylinders, they won't even hardly run. the only fix is a new gasket.
Usually it's a loss of water that's the concern, vapor out the tail pipe is a sure sign.
If you car boils out water within a few minutes of starting, it's because pressure is getting into the radiator from a blown head gasket or cracked head or block.
I don't usually work on other peoples cars, just my own, and if it isn't worth a new engine I just add sodium silicate and run it for 20 minutes, if it holds it's water and doesn't boil over, it's fixed.

hi,, yes a compression test will tell a blown head gasket and condition of the rings.. so you kill two birds with one stone. i think you have a carburation problem more than anything else thats causing the loss of power when hot. its tuned wrong. do a lean drop method on it. make sure all your vacume hoses and diaphrams are good before doing any work. pulling hills will make this vehicle run hot but not on the red zone. when you say abnormally that will tell me you are on the red zone. which i dont think so. as long as you are not on the red it is still in the normal zone for this vehicle specially when pulling hills. i suggest an auxilliary fan if you do this pulling often. :)

The simplest way if you know nothing about it yes. Other than that if you use a machanics stethascope to hear the leak that will work also. Or try ising a whose. The leak is normally between the headers and the pipe itself (normally). If itst a head gasket you will be able to hear it easily with a thin tube to your ear. try it,.

failing a compression doesnt exactly mean you blew the head gasket. It could also mean your valves are not sealing.
Check the coolant, if its got oil in it, you blew the gasket. If you are losing coolant and you cant find the leak and the car is blowing white smoke then you blew the gasket.
