Default Engine problem?

I was headin out to the beach the other day and the engine started acting wierd.

L83 Crossfire

There is a ticking from what sounds like under the left side valve cover. The exhaust started sounding like I had a high profile cam. And some power was gone. The problem has been coming and going for 2 or 3 days now. The oil is good, hasen't overheated or anything.

I was thinking that possibly one of my injectors wasn't fireing right. But they are both flowing good. Could it be a rocker arm? Spring? Sparkplus not fireing right? Any help would be awesome

If you think it is coming from under a valve cover, pull it and have a look.

It could be a lifter that is not holding pressure giving your engine too much valve lash and costing you lift. Pull the cover and see if there is excess clearance and go from there.

STOP driving it before a valve drops into the cylinder and destroys everthing.

That happened on my 85 and it was a rocker arm stud pulling out of the head.
