Coolant/ Water leak 1992 3vz-e

HEY guys.... I've been through some forums and was unable to find anything really useful to aid me in what seems to be a malfunctional gasket of sometype in my engine. About 20k miles ago my engine started leaking water into the cylinders, but not into the oil, and no oil into my cooling system. I tried to jerry-rig the problem by just pouring a few cans of radiator leak fix crap into my radiator and that soon solved the problem, but only temporarily. Now the leak is full blown and i can't travel more then 20 miles without all of my coolant leaking out somewhere. Now it leaks out of a hose that feeds into my heater core, but not because it is cracked, but because pressure builds up inside of it and it just shoots out the end of the hose, squeezing under the clamp. Anyways another leak i saw was a bunch of steam irradiating from under my top part of my intake manifold, but i took it off and i can't seem to find any broken hoses or anything, anyone got any suggestions? It would really help.

You almost certainly have a blown head gasket. I had one on a 91 3.0 and it didn't leak into the oil either. When I replaced the HG I saw why, it was leaking directly into a cylinder and steaming out the exhaust. Your other problem is probably caused by the stop leak blocking a water passage and now you're getting a build up. Good luck with it.

hooray such lovely news.
well it took me like two hours to get the manifold off, the rest should take me about a day, hooray for weekend projects. About the heater core thing though, I wonder if i can just use some type of radiator flush to clear what ever is blocked, i'll give it a try and let you guys know.

sounds like the stuff u used to fix the leak got a caught in the heatercore. you may be able to run it out after the head gasket change.
or you can run a hose threw the heatercore while you have the topend off, thats what i did just in case i had anything in there....cheap way of cleanin shiat up...

also.. remember to check your freeze plugs under that manifold. I also at one time thought i had a blown headgasket, turned out that those three freeze plugs near the knock sensor had corroded away.

good luck!
