is the crank bolt breaking also or just the alinment pin on the crank gear? the crank bolt is a one time use only bolt with a very specific torque.

Just the alinment pin is breaking off.

how have you fixed it so far? has the crank gear or pulley been replaced yet or are you just trying to replace the pin?

unfortunatley thats probably the cause of the continued breaking. the pin is made into the crank gear and not available seperate from the manufacturer. ive heard of replacing the pin with a roll pin from the hardware store, but it doesnt sound like this will work for you.id replace the crank gear and probably the crank pulley also. if it hasnt been done yet it would also be a good idea to replace the timing belt if its past 60,000 miles
