Feck sake thats a shame! Its possible the number 3 valve and guide where damaged by incorrect timing causing a valve to be bent and then subsequent damage from the bent valve moving up and down inside the guide.

Possible but this would happen pretty quickly would it not? I've done almost 15k in this. Ar and it only started burning oil in the last 1k. Surely it would ruin the guide pretty quickly after the belt was done last?
