Laying under the jeep doing my oil change i noticed they i have a few droplets of Antifreeze hanging off the bell. Is there a freeze plug on the back of the block behind the flex plate? I already checked the plug on the back of the cylinder head and it shows no sign of coolant. when it sits it leave a little spot about the size of a silver dollar. I went to walmart and bought some stop leak and added it in hopeing i would get lucky. I just had the intake/exhaust mani's off replacing the 5 freeze plugs on the side of the block (they are dry). i have since put 7K on it. Those plugs were 1.5" does anyone know what size the one on the back of the block is if there is one? and can it be replaced with the trans dropped?

Ouch you should never use stop leak. That stuff i one of those thing that is great the first year then messes everything up for years to come, water pump, thermostats, heater cores... Ugh I would flush that chit out as soon as you can.

Yes there is a Freeze plug on the back of the block. I think I have pics...

You can see them pretty clearly here

X2 on getting rid of the stop leak....Friend of mine dumped that crap into his Pontiac back in high school to get his radiator to quit leaking. It sure did stop the leak, but it also stopped the rest of his cooling system from working in the process. Water pump, hoses, tstat...you name it...it was replaced because of it.

well at this time its my only option till my buddy comes back into town to give me a hand...how much of a pain is it to pull the engine..?? and leave the tranny in the truck? i need to also install new motor mounts and have a minor weep from the WP gasket.
