I had a small tick that you could only really hear at idle, not even loud enough to be bothersome! driving last night and it turned into a tick loud enough to turn heads as i was driving!!! Found issue pretty quickly and was able to fix it at no cost! Was all my own doing! When i had head off i removed air rail! I plugged all the holes in the heads with plugs but one as hardware store only had 5, remaining one i simply crimped the pipe about an inch up and cut it off! apparently i only finger tightened it!!! if fell out!!!!
Felt a bit foolish as like i said it was my own fault, but on the bright side its fixed and the remaining plug i need to buy is back on my shopping list!!!

This is why i need to write stuff down!!! memory aint what it used to be!
