I have a 2007 Chevy suburban LT Z. I was driving home on the freeway and the engine suddenly started tapping. My oil pressure was fine and my oil level was fine so I took it into a mechanic to get it diagnosed.

The mechanic determined that a lifter on the number seven piston has "collapsed".

I assume that I am not the first one to ask questions on how to remove the cylinder head and change the lifters. Can anyone direct me to a good thread regarding how to do this? Or maybe there is a better solution…
