Hey guys,

I've been searching ausmini and also googled it, but havent found an answer that satisfies, hence raised another thread on it. :oops:

Do I need the breather at the back of the engine if i have one on the rocker cover? In otherwords, how many breathers do i need?

Its a 998, upgraded head, 1.5SU and extractors. If that makes a diff.

(I have found lots on where breathers should be vented, atmosphere or back to carbie and I have decided I will hose the breather from the rocker to the carbie)

Thanks as always.

If the one on the back of the engine is a crimped pipe, that's an air inlet and not a breather. Leave that one open to atmosphere.

If it's a canister, plumb it and the rocker cover to the carb vacuum port.

On a 998 you don't need tons of breather capacity, if the rings are in good nick the rocker cover will probably be enough but it doesn't hurt to have more.

Ok, thanks for the quick reply!

There are two blank covers at the back of engine, but I do have a cover with a canister thingo in my spares pile.

I'll plumb the rocker breather to the carbie and leave it at that.

Cheers
