You do have vacuum for various functions such as climate control etc. They are small diameter rigid "hoses".
Get a can of spray carburetor cleaner. Yea, you don't have a carb, but find a spray can at your favorite parts store. Start the engine and spray it near the hoses. When the engine speeds up, you have found your leak. You can buy new "hose" (Toyota will probably have exact replacements, for an awesome price) or depending on the break, electrical tape may solve the issue.

Very well diagnosed. You are right. I had a good look over the air inlet side (I'm not a mechanic at all).
Saw a couple of worm drive clamps holding 2 areas. Took a #3 phillips screwdriver, one tightened up about 1 1/2 revolutions. That is a lot, the other less than a full revolution, that is a significant.
Idle speed is stable now, it's not sucking air in where it should not.

Congrats

A vacum hose leak will cause engine to run rougher it will interfere with manifold pressure sensor. Idle will be all over the place yet this can happen with high KMs as Idle Air Controller valve carbons up which doesn't allow it to work properly.

A vacum leak will be really noticeable at idle and small throttle openings when vacum is higher. At full throttle a vacum hose leak doesn't make much if any difference.
It's not something you will hear unless bonnet is open and you're searching for it.

Vacum is highest with 0% throttle opening.

That said all rubber hoses have finite life after about 15 years they can be questionable.

I had a radiator hose split once coolant pissing out i used electrical tape wrapped around it like a tight bandage to get home after topping water up. With older cars probably wise to keep a roll of electrical tape in it.

With high kms it could be worn bearing in alternator or water pump as setanta suggested.

Thanks guys. I agree all the hoses should be changed. If that one had 'changed', others are close to that too.
New water pump is a good idea, I asked the garage about one 3 years ago, it was ok then. It had a new alternator , radiator and tensioner pulley about 3 years ago.
Could be a good list for the next garage visit.

1/ replace air inlet hoses where possible.
2/ Install new water pump. (Preventative maintenance)
3/ Stop oil weep around rocker box.
4/ New spark plugs due?

They should have put new radiator hoses in when replacing radiator if so they should be ok.
Heater hoses use coolant from engine to firewall about inch thick they would be the weak part of cooling system.

It's consequences of failure to consider.
With coolant leaks it's engine meltdown if you don't turn engine off.
Vacum hose failing means engine running rough misfires etc at less than 10% throttle opening and idle, provided you're not driving hundreds of km you can get home.
There is a thicker vacum hose to brake booster if that fails you lose power assist meaning brake pedal needs double to 5 times force to get it to stop.

We should be able to rule out what you have replaced.

The water pump will get really noisy before it fails i wouldn't replace that just yet. Older cars (70s-80s) with engine driven fan on water pump could send fan blades into radiator when pump failed. Modern cars have electric fans it doesn't happen with them.

It depends how much rocker cover gasket it leaking if it's only a little bit i wouldn't worry. Sometimes nipping bolts up a little tighter cures it. Modern cars have rubber gasket they're really good older cars had cork ones that didn't last.

Spark plugs last a lot longer in modern cars better materials in them the longer lasting ones cost more so if car isn't misfiring i wouldn't replace them. EFI means car runs better for clean burning so plugs last much longer.

As for the noise open the bonnet get someone to hold revs in range where you hear it and follow where noise is coming from. If you can hear it while driving you should be able to trace it with bonnet open. If you locate source of noise and don't know what it is post a pic.

If your dashboard lights up with faults for engine gearbox or ABS SRS etc some Supercheap Auto shops do diagnostic scanning for around $30 takes about 10 minutes they will give you printout with fault codes and what is wrong. It's the cheapest option for diagnostic scanning most charge around $80-150 with Mercedes being the worst around $330 to plug scanner in to tell you what is wrong.

Thanks Baron, that is great information.

I took it to the local mechanic, he has worked on this car for a about a decade.
He said it is fine, that is a normal noise

I'll see if I can tweak down the rocker box cover

Start with the middle bolts and work your way to the outside in bigger circles when tightening things up.

Thanks, will look at it in a few days.
It's a good old car, we are recently retired so the longer it runs well the better.
It's probably worth $5K, gets us wherever we want to go, is quiet, smooth, low repair bills, good highway car.
If it runs well for another 3 years that will be a big help to our budget.
