While its out it wouldn't hurt to replace the water pump since its just right there unless u have already replaced it. I would also highly recommend to do the timing belt damper since they are the ones that wear out and will make u do the whole timing. These are just things i would do while its out. Just so much easier than when it sits on the car. Good luck
In my eyes, you get bonus points for not destroying the wire that goes to the knock sensor. :th_thumb-up:
