Common Valve train problems

Lately I've been hearing a slight ticking coming from the drivers side valve cover. At idle she ticks softly but as I start rolling and begin picking up speed I hear this thrashing noise that sounds pretty bad. The motor also shakes like I'm running on 5cyl's after it warms up. Detonation has been with this car since I bought it. Changed plugs, wires, EGR valve ran 100oct gas with no effect.

My conclusion is the rocker arm assy, lifters and/or pushrods are the culprits here. My problem goes to anyone who might had something similar going and corrected it or anyone with some insight. I just what some direction as to what to look before I start pulling parts. Know what I mean?

Also living where I do makes it difficult to even do a oil change so I have to choose my jobs wisely. Thanks!
 
It sounds like a problem I had once. The rocker is loose for some reason and you wont know why till you get the valve cover off. Several thing could cause it.
1. Rocker arm bolt backed off.
2. rocker arm bolt broke.
3. Rocker arm worn out.
4. pushrod worn out.
5. lifter shot.
6. cam lobe worn down.
