once again i have bad news as i was searching for hat was wrong with my car i noticed that air and some gas was shooting out the bottom left side of my cooling head so.. i went to take it out and retighten it then i noticed one screw wasnt tightening it was just spining when i took it out the thread of the hole cam out with it then on the other screw on the left side the same thing happend so now i have two holes without threads and i have no clue whatsoever as to what to do hopefully my uncle whos been a mechanic for a while will have an idea at least. Im thinking about maybe a bigger screw so it is tighter in there or in worse case scenerio buy a new crankcase but which one would fit the piston and all that.plz any idea would be usefull
