Can anyone recommend me a breather system that doesnt require the drilling of the cam cover? im having a t35 and Siemans 55lbs blacks fitted so need standard system binning.

 

Bailey mirror image breather

 

I use the airtech one breathing from both sides of the block but you will need a return into the sump and this must be below the oil level.

 

You mean this one?

Yep that's the one plumbed in as per Harvey gibbs instructions, he said you must have the return to sump below the oil level or it will just act as a third breather, the fittings for the block and small filter came from e bay.

 

Any links pal ?

 

These are the fittings I used for the block,
