Hi guys while driving hope the engine in my county started to have a pronounced rattle at the time this happened i was sitting on 90 kph so i droped down to 60kph and drove the 3 klms to my house.
The engine still runs smotthly but there is a deffenite tap tap tap sound at idle but goes faster as the revs go up, and when i do the old long scew-driver to ear on to engine trick the tapping noise is coming from No 1 cylinder.
My question is what to do next? remove the injectors, rocker cover then head? or maybe is it a small end bearing i dont know. The engine has 340000 klms non turbo and gets regular oil changes with good quality oil.

I found it was a loose alternator pivot bolt.

Well tryed the above and the only differance was a miss while the No 1 injecter was cracked open a touch, took the roccker cover off and nothing broken valve springs all intact there is a little play in the valve adjustment but nothing extreme?????????
My worst case suspicion is maybe a gugen pin thats moving about or broken piston rings? I guess its time to remove the head!

Set the valve clearances before going any fyurther - especially as you say the clearances are "a little loose". I have had cases where there were bad rattles and knocks that completely disappeared when the clearances were re-set.
FWIW

SubscriberA while go I had problems along the same lines as you are having. Was a three part problem. All had similar symptoms, a tap or rattle from under the bonnet. One was a uni joint gone, second was a dud head gasket and the third was a shot ejector. Might be a good idea if your motor has not had them done for some time to have the ejectors looked at. Only cost me $400 for mine to be reco`d Certainly caused my motor to rattle and then when the one sus ejector finally gave up it missed fired.
