As the title says, the noise does sound alot like tappets, and it is in time with the revs (Faster as it revs faster). However! I adjusted them not long ago, and it ONLY does it when its in gear and moving. I tried jacking it up and putting it in gear but cant hear it, its only when im moving.
There is a little crack in the manifold (Shh) if that might be causing it...but i dont see how!
