Engine Knock

[winstonwilliams]

I have a loud knock coming from my engine. The knocking is very loud some times and almost goes away other times. I could not find a stethoscope around town, but I went ahead and ordered one off of ebay. I tried to use a rubber hose to funnel the sound to my ear, but I could not find exactly where the sound was coming from. I did notice that the knocking was louder inside of the valve covers. I would think that if it was a lifter or valve problem the noise would be louder under one valve cover than the other. But to me they sounded the same... What do you guys think?

Thanks

Winston
