Bad lifter?How to tell

My friend's 96 Formula has a bad lifter/lifters in it. This past weekend we pulled the intake off, and pulled out the lifter that was ticking. We also checked all of the other ones on the same side of the motor. We replaced the one that seemed to be bad, but it is still ticking. Is there another way to tell if a lifter is bad other than sound? We tried the push the lifter in with a pushrod, but none of them would move, so we know it is not a collapsed lifter. If anybody could help, it would greatly be appreciated. BTW, the ticking is loudest around 2 grand.

Re: Bad lifter?How to tell

all that work and you didnt just replace them all?

for the ammount of work involved, its cheap insurance to buy a new set and install them all NEW...

Re: Bad lifter?How to tell

We are pretty sure it is a lifter, because we adjusted the lash correctly, form what everyone said to do on here. I told my friend to go ahead and replace em all, but he was short on cash, and decided to just do one. Oh well, now we have to pull the thing apart again. Might as well put a cam in while were there.
