About once a week when I start the car it seems that that top end of the motor (cams) are dry. it make the noise for about 2 or 3 sec then stops. 86000 mile oil change at 5000 mile intervals.

 

Are you using Synthetic?

 

Some on this site have mistaken that noise as a "dry start" noise. Then it actually was found to be an odd serpentine belt/tensioner clattering noise.
Double check where the noise is coming from, just to be sure.

 

No synthetic. I'm changing the belt wen. Ill check the tensioner then thanks

 

Check the TSB's, I seem to remember something about upper engine noise.
