truck sounds like a mini deisel!
1986 22rte regular cab 4x4. 306k miles complete rebuild around 300k however that was about 5 years ago.
I have had the truck since january. When I got it it idled super smooth and quiet.
About 6 weeks ago my headgasket blew(old coolant, crappy gasket)
I replaced the gasket with a toyota one and replaced the chain/guides/tensioner with metal backed guides.
Since the headgasket the truck has a really noisy idle...it sounds like a deisel. It starts up quietly in the morning but after a couple minutes gets really noisy.
Its mostly/only noticeable at idle especially when warm. After the headgasket it would do it about half the time and it has gradually got to the point where its all the time.
I have done several valve adjustments and replaced the adjuster screws without any change.
I'm getting very frustrated and it does not sound healthy...
Any ideas?

probably been thought of but your hg replacement did it have all of the oil passage holes in the same spot. im not sure if they are the same as a 22re but there could be minor differences. again just a thought good luck. also heard the rockers can tap the valve cover

I've stethoscoped the whole thing...the noise is loudest without a scope...timing cover is quiet, cylinders at the spark plugs are quiet, oil pan is quiet,
I do hear a clack clack when I put the scope on a couple of the valve cover nuts...the intake side I believe...and the noise changes in volume depending on what side of the nut I have the probe on... It doesn't sound like the noise I'm complaining about...and I don't know what a healthy 22r is supposed to sound like... And it hasn't changed between the valve adjustments. I don't know if it was there prior to the headgasket
The problem noise definitely wasn't there before the headgasket...

check your valve clearance and adjust them, mine did that after i did my hg and I just adjusted them like the manual told me and it purred after that

Have you checked the cat converter? I have had them run fine then suddenly begin to make noise. Hit the bottom of cat with your hand. If bad you will hear rattle. Of couse only do this when it 's cool not hot,
