sury someone can help i have cleaned a blocked rocker cover breather an it seems ok now could it have been the breather?

If the rocker breather is blocked it will cause inside the rocker cover to pressurise.

The t-piece is supposed to be connect to the PCV valve on the manifold. Not sure of the technical reasons but the valve has a one way style bearing in it that can become coked up.

Definitely worth taking the valve off and making sure it is clean inside and refitting the pipe to it.
