I noticed when doing my timing belt the camshaft sproket bolts were not in the centre of the oval holes. The bolts are quite near the end of the ovals but not quite. It has not to my knowledge been off before i replaced it. I just put it back how it was.
Why do the bolts need to be i the centre of the oval holes (or that hole in the toothed inspection window thing) need to be in the middle.
The bolts are best positioned in the middle of the oval holes because it means they have room to move one way or the other. If they're at the end and you need some adjustment range the belt would have to come off so you could move the sprocket over. The toothed window is the same thing. It's just a mark to help you figure out how camshaft timing is. Check camshaft torsion value in engine measuring blocks with VCDS and you can confirm camshaft timing.
