The reason I asked if your primary was a breather type way, way, WAY back at the beginning of this thread is because when oil is allowed to transfer from the primary case into the engine, the incidence of oil wet sumping goes WAY up. The reason: clutch debris, which the c/s seal typically keeps out.

So while the engine may have oil wet sumped first, and then blown the seal out. It's also just as likely that the oil seal blew out, then allowed clutch debris into the engine, THEN the engine oil wet sumped.

No way to tell at this point. smirk

I'm thinking of buying a rotary oil pump http://www.morgo.co.uk/rotary.html#triumph_rot to put this issue to bed forever on my machine.

The rotary brings its own set of problems such as losing prime and where to send the surplus oil, its for racing not for roadwork.

How would one be able to tell this ? Are the Map / Triple filters like this what is "the right way " for flow on these ?

Hi,

If, by "this issue", you mean oil seals blowing out, you should read John Healy's past posts on the subject before you part with your money. If I understand John's posts correctly, the Morgo rotary pump will exacerbate the "issue", as well as bringing a few others of its own. frown Fwiw, as a long-time triple owner, I too thought a rotary pump on my 500 would be A Good Idea; thankfully, I read John's experience before I parted with my money. whistle

The filter cartridges made to fit the compartment in the Triumph and BSA triples' crankcases do not have "a non-return flap" as such. However, certainly on the triples, the oil enters the hole in the centre of one end and flows through the filter itself from the inside out; this way, any filtered matter is held in the centre of the filter - instead of dropping off the outside - when it's removed for replacement.

Hth.
