Relating to the matter of bushes for the light 15 water pump, look carefully at what you get from your supplier. They are supposed to be sintered brass or bronze, you fill them with oil and gently squeeze the ends between your thumb and fore finger and watch the oil ooze out of the pores. The bushes I was sent were NOT porous, I had to drill a hole down through the oil feeder to get oil in. I have since discovered that these porous types of bushes are available from most bearing suppliers and not only that there is something even better now available, read the following extract,

“Composite bearing material conisting of 3 bonded layers; Steel backing bonded with porous sintered bronze interlayer which is impregnated and overlaid with polytetrafluroethylene (PTFE).
Operating Temperature -200o to 280o Celsius. Maximum load 250N/mm2. Requires No lubrication, provides maintenance free operation. Exhibits low wear rate, Seizure resistant. High Static and Dynamic Load capacity, Good frictional properties with negligible stick-slip. Resists Solvents, Compact and light. No water Absorption, Electrically conductive and shows no electrostatic effects, Good embedability and is tolerant of dusty environments.”

I am in the process of fitting these to all the dry linkages of the gear selectors which should take out a lot of the free play for the gear changes and keep it that way.
