Twinspark cambelt advice
My twinspark has had the metal tensioner fitted to the timing belt at the last change. It has since done 3 years and just under 30000 miles so I'm replacing the belt next weekend.
My question is: with this new tensioner design, does that part need replacement? I know the old plastic ones used to fragment and that is now not possible. The only other possible failure is the bearings.
I feel this is unlikely, so I was going to leave it another 3 years.
Has anyone experienced bearing failure of this kind?
The idler on the other hand is plastic, so I'll replace that.
It brings the total cost down from £80 to just £35.
Edit: I have a feeling the responses might be unanamous about this...
