i love these cambelt threads when people who no nothing about engines or pd cambelt loads (as it gets a lot of load when it compresses the fuel in the injectors ) also did you know the bottom pulley is oval on most pd to allow more of the belt to be in contact with the pulley at injector firing point and at vw were i work and do a hell of a lot of belt and engines £300-400 is a lot cheaper than a smashed engine. because some ones not listening it been 60k or 4years for a long time at vw and there the the same engine as yours but hey don't listen and don't cry when it all goes tits up
I guess you've done hundreds, are you saying there's no more strain on a PD than a petrol engine , I ve never seen an oval pully but some do have teeth missing (on purpose) VW training doesn't negate everyone else's experience however silver you may be
