Tapping noise Options

[dabbill]

When my car is first started in the morning there is no noise, but after i drive it a while after its warm. It makes a sound mainly around 3k rpm. Sounds the same as a rocker tapping on a v8 engine. If I step on the gas it goes away and come back like 5200rpm. Also when the engine is warm, and I rev the engine you can hear it when the idel is comeing back down. Last night I pulled off my valve cover and checked my cams, they are tight. I just droped a new engine in it about a month ago. Stock one imported from japan. Suppose to have 25k miles on it. My old engine made the same sound. The only thing the same between the engines is my full intake and exhaust.

Just pray to god its not rod knock....is it pretty audible or is it fairly quiet? Some engines have an audible tap coming from the valve trane.. the 22RE in most Tacomas have a really audible tick...I'm not quite sure what causes it but last time I check our engines don't have a very loud tick but if you listen closely it is there. I would try a valve adjustment and see if that does anything for you. Its pretty simple and you can do it in an afternoon.
