LS7 breather again

[Watto GTR]

Hi Guys i know we have had this thread before but i just want to get it right (or try at least) At the moment i have a pipe from the crank case to the vaccum port on the inlet manifold and pipes from the rocker covers back to the top of the oil tank. This causes a vaccum in the oil tank, is this correct?
Thanks
Keith

If you want to do it as per factory recommendation - You need a breather hose from the top of the dry sump tank to three rubber breather hoses - one to each rocker cover and one to the MAF housing elbow.
