Hi guys. I've joined up as I've just had an almighty argument with my brother whilst changing the cambelt on my 2000 Bora SE 1.9 yesterday! Hopefully someone here can help me win the argument and prove he's a muppet We had a crank locking tool and cam locking tool in place and had got the new belt on the sprockets ok and were at the stage where the belt needed tensioning. He wanted to loosen the three bolts that hold the camshaft on (the ones for altering the cam timing) so he could tension the belt. I told him not to as it would alter the cam timing and could cause all sorts of problems. He couldn't see this and that's when the foul language started! I let him do it just to get the job finished, but I marked the pulley first in case it did move. It moved a bit, then returned to its original position so all is well. So, am I right in thinking it was a bad idea, bearing in mind that we didn't have any equipment to check the cam timing? Is it better to just remove the locking tools and wind up the tensioner? Thanks.
