Why does my 93 sound like a diesel?!

[Dr. Dyno]

Thanks for all the replies! I was listening a little closer to my engine and it sounds like it's mostly coming from the top like valve train noise. Do the rocker arms ever need adjusting like on Chevys or do they need replacing?

The rocker arms are non-adjustable but if you hear ticking directly under the valve cover, it's probably a sign that the rockers and/or the pushrod tips are worn. This is more likely if they're not getting adequate lubrication because there's sludge accumulation in the engine.

My '01 with 42k miles makes a sound most of the time that sounds like a faint timing chain rattle. Sounds sort of like a diesel.
