My 225 has been clicking at a regular rate at idle. "tick, tick, tick..." Rev it up a little and it goes away, calms down and click returns. What is it and what should I do about it? Thanks!

Need more info - could be anything from a loud Timex to a belt, an alternator, lifter, wrist pin, or flex plate.

Where's it coming from - front, rear, middle, left, right, how loud, cold, hot, both etc. Missing, what engine, what trans etc.

Then maybe ---

Coming from inside the engine, hot or cold. 225 w/ TH400

Could be a lot of different things, has it been getting progressively worse? My old 71 w/225 had a habit of eating timimg chain tensioners, when it had chewed through the composite block on the tensioner it would tick on the metal backing. Check to see how much slop you have in you timing chain. Could be something else, but that's pretty easy thing to check. You don't want to throw a chain, it could get ugly.
