I know the top bolt is bottoming out, it has a pointed tip that got flattened because of this. The bolts came loose and my engine fell, that's why they're stripped, i replaced them with something longer, i can tighten them pretty firm, but they worked loose again, i took them out and the top one has a mystery greese on it. It's grey in color, looks alot like ARP assembly lube, i also found this in my throttle body when i removed my charge pipe. Is it possible i broke through into my coolant jacket? I didn't notice when i rebuilt my engine if the hole for these mounts went through, maybe i tightened into a sleeve and cracked it causing gas, oil and coolant (running small mixed of the yellowish coolant) to get onto the bolt?
