[QUOTE="Marcus Bowden, post: 131686, member: 3287"] It certainly wasn't fitted with a Honda oil pump as my cams are well into their third 100k miles, the next Comet engine ("C") will have a plain floating bush B/E and the Honda pump feeding drectly into filter housing so all oil is fed into the timing cover with a seal around the quill so keeping as much pressure as possible as I want to see at leased a few p.s.i. at the cam rail,but with cylinder supply blanked off. The "A" Comet that my mate Bill has just assembled is fitted with a plain floating B/E bush, with the supply oil pump increased by half as much again by increasing the width of the gear wheels by 1/16" from 1/8" so now 3/16". Mr Vincent mentions in his autobiography that he wished he had kept his original pump design as it was certainly superior with more and a constant flow to the intermitant post war design. bananaman.
