The first thing that popped into my mind was to check the motor mount. Can be loose, can be cracked, can have something inside that rattles about.
Beyond that, it would be helpful to know if you have either or both Weeks kits installed. (what egr components are left)
Serpentine belts, can develop cracks / defects that will make many odd noises.
Does your power steeriing fluid reservoir have proper level?
Engine vibration can cause the transmission dipstick to tick against the coolant recovery tank, and, if present, the engine cover. If it's popped out, it can also tick against the end of the tube.
power steering is great.
the engine cover is gone.
I will need to check the transmission dipstick. I'm not optimistic this is it.
I tuned out the egr. no weeks kit.
My thought relative to this, That an exhaust leak can often make a ticking sound very much like a failed hydraulic tappet. If the tube that passes from the rear of the exhaust manifold, around the back of the head to the EGR valve, can have a split, crack, rust hole, or other leak, even if the EGR valve is electronically disabled, it will make an RPM frequency sound, quite like a ticking noise. The Weeks 2 is the kit that disables the exhaust at the rear of the manifold. It is not difficult to install, but you still would need a block-off plate at the other end of that tube, to prevent potential leakage of pressurized charge air from the FCV / intake manifold. This, again, is not difficult. WWDiesel has posted the dimensions many times so they are readily available in many threads. The weeks 1+2 combination has the beauty of allowing the complete removal of both EGR and FCV, replaced with a smooth, light, high flowing elbow, and everything necessary to eliminate potential coolant leaks, and all the advantages of being free of the EGR/FCV problem. Is it worth the price? (*shrug*) I can't answer that for you. For me, it was.off topic: is stage 1 or stage 2 weeks kit easier to install?
Stage 2 is easier, but without the stage 1 or a block-off plate on the other side, it won't accomplish your goal. A shop said the mounts are fine. If it were mounts would noise go away when motor hot?
I don't know, but I've seen mounts make really weird unexpected noises, and it seems these are no exception.
