Im sorry for the bad english:/ Im from Norway

I am building a catch tank setup, and i have the design of the tank and venting of the top (vavle cover) finished. (tank is under construction)
But as far as I understand it would be beneficial to vent the bottom part of engine also. Is there any places where I can do this without drilling into something? If not, where is the best place to tap in?

I have tried searching for this but it seams few has vented the bottom part.

thanks

Sideways

The bottom is vented through the valve cover. There are several passages through the head.

Oh, so there is no point in having a vent to catchtank from bottom part?

I'm trying to find a test t1 race did. On a b series you always vent the back of the block. With (4) -10 lines, 2 on the valve cover and two on the back of the block, he only saw 0.5psi of crankcase pressure. The s2k engine is more efficient due to more passage ways but who's to say its NOT beneficial.
