So today I figured out what this weird vibration was that was coming from my engine bay. It was a wrench that was still connected to my header bolts. When I first heard it I didnt think much of it, I wasnt really worried about it. But then today I was adjusting my valves and putting my phenolic spacer on and BOOM, there it was in plain sight lol. It was on there for about two weeks and it didnt fall off. I feel like an idiot!!!
LOL!!!
Haha NICE!! I would hate to have to go through draining all that again and taking the rad out just for one bolt.
