ATF = Automatic Transmission Fluid

a lifter sits between a camshaft lobe and a valve. cars with solid lifters must be frequently adjusted for valve clearance. cars with hydraulic lifters use oil pressure to 'pump' a lifter up to proper clearance.

when an engine ages, hydraulic lifters can gum up a bit, causing them to sag. this creates a gap between the lifter and the camshaft. this gap is the source of 'valve tick.' the ATF can, in some circumstances, clean the lifter to a point where it functions properly again.

additionally, saggy lifters can be caused by low oil pressure (worn out oil pump, worn bearings, etc).

but my clicking noise is pretty much constent...like as long as i have some throttle...the wheel of fortune wheel sounds is there.....from my understanding..from ur explaination...it is only suppose ot click ONCE..when i step on the trottle correc tme if i am wrong

thanks!

CV = Constant Velocity
