And yes - aluminium is also a metal - we do of course mean STEEL backed pump -

dont think that's a dig at moi ! I wasn't trying to be funny or anything, just that the blinking stuff (plastic) gets everywhere.In the mower world where I ...sadly... get involved, I have come across plastic camshafts and ...wait for it... conn. rods!!

So- the bog standard £16 oil pumps from Minispares are ok to use in any circumstance? The thing that puts me off the expensive ones is that they will wear out even faster if they are machined to better tolerances and of all aluminium alloy, with the unfiltered oil passing through.

MinI Spares GLP138 will be fine for your engine, O.P. That is a steel-backed pump
If you have a really high-performance engine a Metro Turbo pump is then ideal and most of us involved in Historic motor-sport use the Turbo pump. Any excess initial pressure is bled off by the PRV, but when the oil is very hot the greater pump capacity is good for keeping the oil flowing in high volume and thus helping with the cooling as well as maintaining bearing protection.
A note of caution when fitting a 2-bolt oil pump onto a block drilled & tapped for a 4-bolt pump. Always make sure the holes for the 2 unused bolts have not been drilled into the water jacket. If that has happened the oil can get into the water. If that has happened, plug the redundant holes properly.
