Ok, just had a weird thing happen with the 33.
Hasn't been driven for over a week, so i take it for a quick spin around the block. Get home and can smell burning rubber, popped the bonnet and the power steering belt has decided to walk off the pulley by one rib, but only on the pump pulley?
Belt is not over loose (possibly a little loose, no adjustment left, time for new shorter belt!)
Going to check harmonic balancer bolt, just to be on the safe side.
