Awesome, thanks for all the advice.
yarrgh, good point about the rear cover. It was leaking quite badly. I thought it was the oil pan gasket, but it turns out it's that cover. +1 on getting a new one.
I'm not sure about the pullys.
the one with teeth spins freely but is loud like a skateboard wheel
The other ones are quieter but seem slightly off axis,
The tensioner seems ok. Doesn't spin for a long time
Water pump seems a little jerky when you spin it
but the good news is that the block mating surfaces are flat.
the bolts all mesh really well, no problems there. the only defect I found on them are:
I think they should be ok to be reused. It looks like a manufacturing defect rather than threads getting warped.
So how's this for a shopping list?
- fel-pro gasket set
- rear crank case cover
- pully set (no tensioner)
- timing belt
