Well guys im back yet again, with yet another problem. The water pump let loose while dring down the interstate, evidently i didnt notice the temp gauge maxing out quite quick enough. We replaced the water pump fired it up and heres what we got... #1 when cold the engine doesnt knock, and once warm and under a load it doesnt kock, but when you let off the clutch it is a very loud fast tapping noise. #2 It has a severe power loss, but idles fine, starts fine, and is fine until warmed up. I believe we're going to take the valve covers off and check for a failing lifter etc. Thanks :SNSign:
