L67 Tap or Knock

Recommended Posts

Ok, I've got a 2005 L67 monte, I was starting my car this morning (Its cold) and noticed a tap or a knock noise when i was in front of the car. I popped the hood and could not hear it at all the intake makes to much noise. When i got over on the passenger side and leaned down I could hear it more.

 

The sound to me sounds like something in the valve train. But I don't want to blow something up, So if anyone can help me figure out if its knock (ROD) or Valve train i would appreicate this..

 

The other reason i think its the valve train is due to my higher shifting points. if thats the case I've got some INTENSE fucking problems......

 

I plan on swapping out the current rockers for 1.85 split ratios but thats not in the books for next year. So any help is GREATLY appriecate
