Well it's odd, before I brought it in it had an engine knock sometimes only, and it was faint. But after he got it running, he told me over the phone that the engine knock was very loud and gave it weeks, not months if I drove it.

I haven't heard it yet with my own ears, I'll be looking at it tommorrow. I'll see if it goes away when warmed up.
