Okay, you lost me on this. Water shouldn't come out of the timing chain cover. Are you sure that is the part that is needed?
If you are, expect around 4 hours of labor and a used cover shouldn't be more than 20 dollars. You will need gaskets, so add aprox 30 dollars for them.
Please understand that the cost may be different based on where you live. Also, yes the bolts can break, but they shouldn't on the timing cover.
Let me know if you have other questions. Also, sorry it took so long to get back to you. I was out of town for a couple days.
