I know the 3.3 came in a lot of vehicles, but I was wanting to know some more on valve train wear. Who here has had one apart and inspected the rockers and rocker shafts on a high mile 3.3/3.8? I got a little bit of clatter from the top in the rear and also it sounds like the timing chain might even be sloppy. The engine looks clean if you peak in the V/C through the oil fill hole and I haven't skipped an oil change, but with 190k on it the slight clatter is a little unnerving.
