I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Sounds like a timing belt tensioner. Usually as you rev the sound goes away, that is because the belt has enough momentum to loose the slack and stop the slapping of the belt all over the covers. Saying that it is worse when cold is also another sign as the oil that is left in the TBT is sluggish and the piston wont move as well until it is warmed up

Since you already have the cam gears showing, check to see if there is slack in the timing belt in any area, that is probably a indication the tensioner is shot.

It could be either, or both. You guys probably figured this already, but since the timing cover is off the sound is less muffled. Certainly not my area of expertise though.

Kid Hauler:
