3.0 noise
my problem is the noise I get when the engine is at higher RPM like right before it is about to shift. the noise only seems to occur when the the truck is in drive and moving. It sounds kinda like vavle noise to me but its hard to tell for sure when it only happens when it is moving...it is a tapping rattling kind of sound.3.0,180000,auto any help or ideas?

Is it always, or just when it's cold or been parked a while? Mine does it too, but with a 2.5. I think I've got mine narrowed down to a throwout bearing or something in the trans, because it sounds like it comes from lower and further behind than the valvetrain.

Well I found the problem..I think... it seems the camshaft synchronizer is the culprit,I pulled the CPS and found it was dry inside the whole thing so a couple of squirts of WD and the noise went away

WD is NOT going to fix that problem. It is more of a solvent than a lubricant. I predict you will hear it again soon. The synchronizer most likely needs to be replaced.

I would have guessed that what you were hearing was detonation (a/k/a "pinging").
In any case, nice find. I agree with Tom, you should change out the cam synchronizer assembly ASAP if it is making noise. It is important to note that 1996+ 3.0L vulcan engines have a gear on the camshaft synchronizer shaft which interfaces with - and spins- the oil pump drive shaft. Which means that when the cam synchro shaft fails and stops spinning, the oil pump drive shaft also stops spinning, and the pump stops pumping. In such case you can pretty much say goodbye to that motor.
