My fto started a slight knocking/tapping sound on starting up. It used to only last a few seconds and sometimes didnt even happen. Now the noise is lasting longer. Any ideas what it could be?:blink:
Without hearing it, it's impossible to be 100% accurate but it's most likely the cam followers. This is a common fault which no amount of oil changes will cure. The way ahead is to fit new followers, along with good oil and a new filter.
