Started the old girl up this morning and hear "tick tick tick" in time with the throttle. Got a better chance to listen to it on my lunch. Sounds like it'* coming from one of the rear cylinders (closest to the belt.) What do you think? I'm thinking valves, but??

Something like this is hard to diagnose just over the internet... I just hope it'* not a bottom end knock.

I'm not sure what it is now, becuase when I left to go back to work on lunch, it dissapeared. I asked my boss, and he said that it could have just been some carbon build-up. I suppose I'll get some fuel system cleaner and just hope it doesn't come back.

Might have been a lifter not getting enough oil. Might have had something blocking the flow that has since passed. When did you change your oil last? Have you checked your oil level?

Changed the oil about 900 miles ago. I did use an engine flush though, so I suppose that could have something to do with it.
