Later Alloy Body Oil Pump in K0 Bomber
MrDavo:
It looks a lot like the one I took out, and am probably going back to.
Like when I get gout in my big toe, the exhaust cam suffers because it is the furthest thing from the pump, and the last thing to get oil on starting from cold. It is concern about this that makes me want to increase the oil flow.
Johnwebley:
on the question of cold start,and oil getting to the important bits ,could you use a modern 0w-40 oil ?
this will give good flow when cold,and "body" when hot .
runs away to hide behind the sofa !!!

Why hide behind the sofa ?
I had not good results with 0W40 oil regarding cam issue's. The layer of oil seems not strong enough to resist the pressure of the tortion bar.

Am looking forwards to the outcome of Jensen's tests on the fully synthetic oil, that shows some real potential. I have looked closely at Ash's NOS oil pump and there looks to be subtle differences to my NOS item. How can you tell which version of pump you have, and what are the differences, and do the differences matter? I have posted some photo's below. By the way Ash, mine was a little more than £40 but as you know you have to grab these things whilst they are there. ;) Thanks all.

Jensen kindly explained to me on the phone yesterday that the hole in the gauze filter on the original version of the steel pump was caused by fatigue of the wires due to the oil flow, which is pretty incredible. I plan to put the NOS later version in my engine and put the alloy body one I bought back on eBay.
Jensen has bought one of the early carb. upgrade kits from me and is going to evaluate on his bomber, in due course. Thanks for all of your sterling efforts Jensen !!!
