man, sounds bad. pull the valve covers and pray valves either need adjusting or new lifters.

the quality sound of the video is bad, is just a little "less" noisy.Yesterday i put the additive for hydraulic tappets in the engine oil, and now you can hear, only a clear "click,click,click"...

well, try new tappets if you want to go that far, or live with it

thx a lot for your help, you're the best scotty! :P
