There is a some knd of a clicking/ticking noise when I step hard on the gas. I think it could be a noisy valve. How do I check for that.

Eg. I am driving 40 mph on the 2 gear(5 spd) and the Rpm's are mid to high but not at the yellow line (5000). When I hit the has it makes that noise for a half a second and then it is normal.

This only happens at high RPM.s

Ps. The car has 100,000 miles, always oil change on time,

Any sugestions would be aappreciated.
