Thanks for all the pointers, saves a lot of time and trawling.
.............great site for info, keep it up!
Quick one on the filter - remove rubber seal, smear of grease or oil on BOTH sides, refit and screw up tight BY HAND(S) and it won't come off. Use a strap or hex and you'll need a hammer/screwdriver to break it loose - very messy!
