Having trouble with front motor mounts (behind radiator) on 4 cylinder with
172k miles. Top bolts broke in two, think I can drill them out and re-tap. Threaded portions of cast iron bosses broke away from block on two bottom two bolts.Anyone else have these problems? If so, what was the fix? Can I weld the broken bosses back to the block or should I simply have nuts welded on? Car has never been in an accident. Thanks in advance. F
