I have a 1989 IROC with the L98 350. While the car used to be my daily driver, it has been off the road for about 5 years. I would periodically take it out to start it up and clean it. This year I decided to start driving it as a weekend car and I've noticed a persistent ticking noise both while idling and driving. My guess would be that it's a sticking lifter or valve since I hear it coming from near the passenger side valve cover.

Now I've heard of people using 1/4 or 1/2 a quart of ATF in the crankcase, or Marvel Mystery Oil, or Seafoam to deal with sticking lifters?

What would you guys recommend? Any tips or tricks that may help alleviate the ticking noise without having to tear apart my engine?
