I'm told its by shims-an expensive process, even by exchange. WARNING: Special tool req'd, ALWAYS insert shim with writing DOWN! (so it doesn't rub off).

They are adjustable but rarely need adjustment. The B23E engine, like all B23XXX engines made by Volvo are noisy beasts and that is the nature of them.
You asked about a good Volvo mech. in Sydney in another post- I can't tell you of a good one but I can sure tell you a bad one. Precision Automotive in Mascot/Botany- they rip you off plus they do very poor work. They have f**cked me around a few times, never again.
I have a 240 and do the basic stuff myself. For more complicated stuff I go to Killara Garage at Killara (on the Pacific Highway). They know Volvos (a couple of the older blokes worked at SVM Lindfield) and seem trustworthy. They're a bit pricey but I think it's worth it.
I used to have a Volvo with Kjet an it also had a rough idle- they all seem to. Don't worry about the motor- the B23 is one the toughest Volvo ever made- just clean the flame trap and change oil and filter regularly and they will go forever. The later version B230 is not as strong.
Also, another good Volvo website is www.brickboard.com and also www.turbobricks.com.

The B23E shouldn't have excessive valve noise. A lot of the engine noise comes from the v-belts. If the noise is bothering you, you can fit a hood blanket from a 240 turbo which cuts the engine noise significantly. As Manxman said, the valve clearances are set with shims. In most cases, you only need to change a few shims as you can swap your existing shims around to get the correct clearances. You can do this yourself-take your time measuring all the clearances and shim sizes. There's a special tool for pulling the shims out with the cam in place but you can take the cam off and replace the shims that way if you want. If you take the cam off, it would be advisable to change the timing belts if it's old.

Thanks guys, I know Killara Motors well, I grew up 2 streets away and used to know the owner etc. People have mentioned cleaning the flame trap but I still have no idea what it is or where it is, can someone help me? It's nice to hear the B23 is such a good motor. mine doesn't drip or burn any oil at all, just a bit tappety. My biggest problem is the worlds noisiest main fuel pump, it's driving me nuts. I am doing the inlet manifold gasket tomorrow, maybe that will kill some sounds and improve the idle a tad. The car is in such good nik I feel responsible to make it work perfectly and I am a bit fussy I guess. Keen on the hood blanket idea also but not sure what it is?

I have just replaced the head on my B23E engine, and found that the shims were a bit tricky to remove, but could be done with your fingers. Just that they are such a clean fit, they need to be drawn directly upwards, and they should then slide in/out fairly easily.

If there is any noise there, possibly it is the hushers underneath that may be worn. These are small rubber gizmos, like an o-ring that sit on top of the valve stem, dead centre of the shim.

I don't really see how it would be possible to remove these with the camshaft in place though, special tool or not.

There are actually 2 special tools that you need. 5022 which presses down the tappet and 5026 which is a pair of special pliers for removing and installing the shims. Sorry for the confusion.
