Well, a very faint knock got really loud this morning. It's there at idle but not very consistent through the rpm's. Rev it up and it's there through around 2 grand then it's less noticeable but let off and it disappears until it returns to idle.
I'm pretty sure it's a rod bearing but a co-worker would have me believe it's a spark knock. Either way I'm taking it to a local shop tomorrow to confirm my fears and I'll decide what I want to do.
So, does anyone have a good source for a quality 06+ 4.2L vortec in michigan?
Thanks
