I think that one of my lifters is making a noise. It is a tapping noise which gets faster as the rpms go up. Anyone know how to check which lifter it is and how to adjust it? Thanks

Mine does this.. and seems most do. Mine has a hard knock when starting cold for a minute.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
I had the same noise in my 4.8, If its a sticky lifter, go buy yourself a can of Rislone from O'reillys and put it in right after a new oil change. It will clean away the gunk that is causing it to stick if thats the problem
