ls...oil breather chamber?

[rex559]

hi everyone, im building an ls vtec setup. while i was working on the ls block, i noticed that it didnt have and oil breather chamber in the back. so my question is should i just leave it like that or should i tap it and put in one from a gsr? hope im being clear with my question. thanks

i run my lsvtec without it but a lot of pressure is built up and really you should do it. there is a buildup on here by gsxrsi and he adds an endyn can which is the best method. The Old One - Energy Dynamics

thanks for the info, i purchased an oil catch can from ebay and was hoping to incorporate that into my setup. do you think that i should just tap the back of the block and put a pvc valve between the block and the catch can? im going to run turbo on my setup so im affraid there is going to be tons of pressure.
