Just a little update....
Now have the original cannister oil filter fitted (thanks again to tinweavel) and I am at last leak free (bar a drip from the crankshaft oil seal).
Little bit of nonsense (but with a story).
Put this Shell Antifreeze sticker on:
Story goes that my best friend from High School had a Saturday job filling cars with petrol at a small filling station in Cowes, he had rolls and rolls of these stickers, being Juvenal we stuck these all over Cowes, lamposts, postboxes, parked cars, shop windows etc etc.
This one remained with me for the past 30 + years, still on it's backing paper, so today I stuck it on the car (though the sticky had long since dried out).
Oh..incidentally, there was one lampost (of the aluminium variety) that the sticky residual from one sticker remained until around 5 years ago when the Electricity people finally upgraded it to a more modern variety but when I passed it always made me smile.
*EDIT* Just been out to the garage and the offside front tyre is as flat as a pancake. Oh well
