Update
-Valves adjusted
-New 911 chip with pump gas tune
-Timing chain tensioners checked. Looked new in there. Chain was tight
-new plugs
At first start up I heard nothing. But then it crept on and was still there.
Stethoscope (amazing) used. Everything sounded great and even. But this knocking noise was most noticeable on the fan house. Honestly. I could not hear the knocking until I touched the fan housing. Could it be the alternator? I’m going to let it cool and take the belt off and see.
