NEED HELP figuring out + fixing coolant antifreeze leak might be head gasket not sure
1966 satellite 361 BB with headers and edelbrock intake .
i am having trouble figuring out where exactly the antifreeze is leaking from . it seams to be coming out from the front of the motor . . i dont think its any of the water pump bolts . ( but could be ) where i think it is leaking , or about where i think it is leaking ( see photo , A is where i see it being wet , then appears to go down the side seam where letter B is , the "housing" between water pump and engine block , were the "housing" meets the block , it then goes onto the crank pulley where it squeals when idling , and puddles up on kframe front center . ) , the only thing that makes sense to me is the head gasket , but i am just guessing . i never had this happen before . unfortunately i do not have a pressure tester . sometimes when the car has been sitting for too long . there is a bit of smoke from the headers that slowly burns off . i assume this is another coolant leak from the header bolts . could this somehow make its way just to the front side of the engine ? i was trying to get this through inspection , so i tried silver seal ( a copper version ) and it did not seem to make a difference . the leak stops with the cap off , comes back when cap on . ( under pressure , 13 lb cap , drips about 1 drop per 2-3 seconds under pressure ) also , when cap was off it did seem to foam up a bit , not sure if thats from the silver seal or air coming in somewhere . no coolant in oil ( on the dipstick anyway ) , nothing coming out of tailpipe thats visible . i dont know too much about all of the internals of engines , but is there any way for it to be coming from an INTAKE manifold bolt ? all help is appreciated . someone i know suggested bars leak , though i am reluctant to use it . i did not want to even put the silver seal in it . mainly because i worry about them clogging up other things than the leak . but , what about "water glass" ( sodium silicate ) ? any thoughts ? thanks .
