Last week I was doing my annual check on the polyrib belt and idler bearings. I had my Bentley Manual on the bench & 101 Projects next to the car. After removing the lower idler, I reverted to the 101 manual (closest to me) for the bolt tightening torque which it gives at 46Nm. Before the torque wrench got to that setting, the bolt snapped off in the crankcase......
I'm sat there with the idler pulley in my hand and the bolt sheared flush with the crankcase. When the shock subsided, I checked the Bentley Manual - it says the bolt should be torqued to 23Nm - exactly half the value the 101 Manual states.

I contacted Wayne Dempsey to let him know the mistake and he is altering the remaining unsold manuals and notifying Pelical supplied manual buyers.
I guess mistakes happen (just ask my wallet) just double check everything you read in 101 Projects.
