if its ticking like a really fast seconds hand on a clock it could be your valve clearances needing adjusted. had that problem on my M3. wouldnt think so at 48k though. try using a thicker oil maybe. no idea where the ICV is though o_O

Just another thought, the tapping wouldnt be coming from the A/C compressor by any chance? if it is then its on its way out.

yeah it does sound like an IVC. Maybe try and search the net for an exploded diagram of your motor or ask honda themselves. it would be an easy answer for a honda tecky. to be honest ive had 2 vti's and the first one was quite tappety, especially on start up, and that only had 38k on it when i got it. think some engines are just more tappety than others. and to be honest vtecs do sound a bit dieselly especially when cold. wouldnt worry about it. just test the performance now and again. if it still pulls well and theres no smoke or funny knocks then it'll be spot on.
