hey I was wondering why you have to cut the lsj gasket?

Yes, for the pcv. These pictures should help you out.

There I go not reading your question correctly. My bad. I thought you were asking if you needed to cut the lsj gasket. Its for the pcv system. Im not too familiar of how it works on an ecotec engine. Its supposed to circulate any gasses from the crankcase back into the combustion chamber for emission purposes...I think.
