I have read several threads with clatter and valve in them on several boards and yes, I still could use some some of your help. (short version: will adjusting the valves help?)

I am chasing down several issues to try to get my aftermarket cruise to work,
I have also recently noticed some valve clatter since it is warming up. This is my first summer with a 22re truck so maybe this is normal.

When I am throttling up, light foot or heavy, I sometimes hear a mild valve clatter, that doesnt seem to increase or decrease in intensity if I floor it or baby it. I am worried about it being detonation. It never clatters while idleing or reving the engine. It only makes this noise under load.

I recently changed the TPS (never returned to 0), cleaned the throttle body, and plenum (yuck), and set the timing by the book (FSM) and a new fuel filter

and 2 or 3 months ago the EGR valve (old one was stuck), plugs, distributor cap, spark plug cables, new air filter, PCV valve and gromet, and did a FSM by the book systems check of everything related to the EGR system.

I was getting 21 MPG, and suddenly I am getting less but I am driving in town more, and using AC so it may just be driving habits.

ANy other ideas, thanks

 

22RE's just tick, thats what they do and underload is common. If your worried about the valves clicking too much, you can just adjust them a little bit if you want.
