Engine runs very hot, bubbles in coolant with red cap off (do it cold) possible oil in coolant or coolant in the oil.

2 cylinders side by side with low compression!

It will start runnin like crap.If you dont have a lumpy cam then it suddenly sound like you do.It will also sometimes pop thru the exaust or carb,and leak water into the oil.IF suddenly the water level is down and the oil level is up.The water will sit at the bottom of the pan so alot of times you wont even notice it when you pull the dip stick.

i was looking at the motor and it looks like from the left side the back of the head inbetween the head and the block water slips out from there i can drive it around no problem and then when i park it thats when the water starts to come out from inbetween the head its not like o my god type thing but it does come out

If it gets to a cylinder you will see white smoke or steam out the exhaust. Sometimes you may not see it but you may smell antifreeze in the exhaust.

none of those things are happening to the motor but i can see the space were the water might be coming down from imma put some high temp rtv seal and see if that will fix it

Be sure to check the center intake manifold studs where they go into the heads and especially if you have the original early model heads on the engine.  The threaded holes in some of those heads for the intake studs are open to the water jacket and are known to seep coolant if sealer was not put on the threads upon putting the studs or bolts back into the heads at these locations.  That particular seep is easily mistaken for a leaking head gasket.  The later model heads went to a blind hole design in those particular holes which alleviates that problem.

install a pressure tester on the rad when cold let run up to temp and see if the pressure tester goes up, if excessive pull plugs let stand and see if coolent in any plug holes hope this helps shakey pete a newbie canuckSmile

Re: what Ted said.

   The water will run toward the back of the engine. When you're driving it, heat from the motor and air flow will evaporate the water before it gets there. When you shut it off, the engine cools and radiator pressure will still cause it to leak.
