Too late, she knows, she knows everything didn't you know!
Anyway, I have been just like a women going backward and forwards changing my mind on a whole heap of things so long as I don't start shaving my legs I think I will survive this turmoil.
Today I stripped off the oil pump and then cleaned out the sump and the area where all the gears run, what a bloody thick mess was inside here. So as it is now is good enough. As things came apart I found the shaft that the cam gear runs on has a slot machined in it for lubrication was choked so that part is cleaned up now. The oil pump was hiding so much crud behind it I could not believe that it just kept on falling out as I scraped away. So after cleaning up the pump I stuck it in my hand basin where I work and submerged the pick up of the pump and spun the gear by hand slowly. Nothing happened then wound it back the other way and presto, it works. Spun it faster by hand and the water spun out like a hose so when it get oil back inside it certainly will pump well. I blew out the water and filled the inside with Lanox then sprayed the outside as well. Next was the oil pressure indicator on the outside of the engine. It was stuck in the IN position so with a bit of Lanox on the outside and I turned the brass elbow that connects to the oil pressure line to facing upwards and filled it with Lanox and left it for a few hours. At last the small button that is suppose to extend out when there is pressure was freely moving. So when it is all the way out I filled the elbow with Lanox and pushed the button in and it pumped out the Lanox so this looks like it will work as well.
Next challenge apart from the cam gear is the water jacket around the cylinder, this will take a lot of doing but I have a very cunning plan for it.
