im finally getting around to doin my freeze plugs in my 77 k10. i found a blazer to build and i need to get my 77 runnin so i got somthing to drive. now my ? is that most of the freeze plugs popped on it. but, 1 or 2 are still in the block. how should i get these out or shoold i leave them in? im not sure if they will leak. but, i would like to replace them while i got the engine out. also is there any internal freeze plugs that would require me to tear the engine apart? i never done freeze plugs b4. any advice would be appreciated. thx
