I just finished a long night at the races when I noticed my car was making a clicking noise, I took the valve cover off to discover one of the valves was missing the locknut to it's tensioner. I looked all around under the cams and everything and can't find it, where did it go? and is this a common thing to happen on honda engines.

 

check your oil pan.

 

check in your pants

 

check your oil pan, just be glad it didnt get wedge between a spring. No thats not normal
