Right under the valve cover??? I'd say it's possibly a rocker arm. But lifter or header leak could sound similar.....if it's not coming from within the valve cover.

Possibly a valve hitting a piston. Thats what the source of the noise my car had was.
We thought it was a bent pushrod until pulling the heads off.

ok sry.ive been bussy,i could try to get a video id have to get my friends camera,,,,,,i have piece o shat headers from flow tech,im runnin with copper gaskets,i thought the same thing but u can almost feel it in the valve cover, i run open headers,i wouldnt think a leak would sound so pronounced,,it was doin this when i drove to holy smokes with it last time,,still drove fine,good power,,i run mobil 1 synthetic, 5w30, with lucas stuff...if it is the lifters,rockers or pushrods that wouldnt be that bad of a fix no?,,maby time to upgrade them but i herd on 86 motors that theres no valve reliefs so would i be able to run bigger rocker ratio and maby get a little more gargle out of it?,,this motor has just over a 100k on it

I heard on the 86 model, the flux capacitor could have shorted out causing your right foot to stick to the floor board causing the engine to over rev. When the over revving occurs you tend to bend a push rod (something gotta give) . This will make the rocker arm to lose tension and it wil produce a ticking sound. Esp with 100k motor. My friend had a 86 and that is what happened to him. Dave has a point with the lifter as well. It could be hanging up on you. If you run synthetic and change regularly, im not sure this is the issue. Your not going back and forth with synthetic and regular oil are you?

They are bolt down rockers, it may be a lifter. You can take it apart to see if you can find anything and it would not hurt to do a compression test and maybe a leakdown test as well.

You run open headers???

so i can just pull the rockers off and put them on without a problem? im only gonna check those and the pushrods first,im hopin its a loose rocker but with my luck its much worse, i have to check my tool box and see if i have the gauge for the compression test.like i said tho,it still runs like the day i got it,i dont feel any power loss with this noise,, whats wrong with open headers? they work fine

Two of the biggest things is you have zero back pressure and it sounds like balls.
