Project with no name here!
So I took the car on the highway last night, did a 3rd gear pull and the car hit a brick wall at 7k rpm. This is what I found when I took the valve cover off...
Shim...
Cam position as is...
Cam position after I turned it a bit. Notice the bucket didn't spring back up toward the cam...
Parts are all aftermarket besides the shims and buckets. HKS cams, HKS valve springs and Ferrea valves.
Now, I'm not sure what started the chain reaction, did the cam throw a shim or did something else break which caused the shim to get tossed? Did I break a spring? Bend a valve? I'm confused. I wouldn't think that the cam would throw a shim at 7k, my cam to shim clearances were in spec as of the last time I checked so I'm not sure what happened.
I wanted to post this to hear your thoughts before I take the head off, which is a given, but still.
Thanks
