Well i got up 2day and taxd,polished and waxd the tits out my stage 3 saff. Took it its 1st blast for 6 month and after acelerating strongly through 2nd 3rd into 4th i slowd down to notice a slight engine noise. It seems to be kinda taping/rattling once iv revd it and the revs are cuming bk down.i lifted bonet and it seems to be coming from back of engine,no4. I did notice in the past coupla year that thers been a dodgy lifter in no4 somwhare as it ticked now and then so wondering if lifters packed in? I left it roughly half hour and took it down to pick up the chinky and it seemd ok,never revd it hard tho (feert to lol) am also thinkn it might be sumthing in bottom end but it got rebuilt 5k ago with ACL mains and big ends and no expence spared. So going to take a run 2moro n see wot the script is. PLEASE wish me luck
