Oil filter
Phil C:
Hello everyone, I thought I'd do an oil change on my 1965 B40F. In between the oil tank and the engine is a modification put in place by the previous owner - basically a valve (an old gas valve I believe) to cure the problem of oil running back down into the crankcase, when the engine isn't running, because the standard non-return valve is not working properly. So when you go to start the bike, as well as turning on the petrol, you must remember to turn on the oil. Anyway, when I took this valve fitting off the tank, rather than find a standard filter, I came across a mesh disc (see photo). In the mesh disc appear to be a few bits of metal. Any thoughts please? Thanks in advance. Phil.

I wouldn't have either in the oil line . Disaster is always looming I have a Morgo filter on my bsa gold star and took the mesh filter in the oil tank out . It dosent make sense to have a filter in either the tank or the line as if it gets blocked the engine is going to be wrecked anyway . On a ride out last year a fellow rider with a norton that he'd had for 40 years forgot to turn the oil tap , he'd fitted in the line , back on after lunch stop and by the time he remembered it needed a full rebuild .
Greybeard:
Why turn the oil off for a lunch stop? :-\ If an engine drains its oil tank in an hour or so there must be something seriously wrong with the pump etc. Surely it's only necessary when the bike's going to be left standing for several days or even weeks and that's normally when it's back home. It's a simple enough task to hang a reminder on the handlebars that the oil's turned off.

Should I be concerned about the tiny pieces of metal? Phil.
