Thoughts on Crank case evac systems?

[NateD4]

What kind of oil do you run?

I don't understand why your oil is trash after only a few hundred miles...

Never used them but you still see them now and again.

I've got to modify my headers this spring for a different exhaust setup anyways so i was thinking about adding in one of the old school crank case evac systems like the one that Summit sells. http://www.summitracing.com/parts/SUM-120108/


My ITB setup combined with the cam cause very low engine vacuum at idle and cruising speeds, my oil is trash after only a few hundred miles. I'm sure the PCV system is doing very little.

Most reports on these types of setups say you can usually pull 2-3" of vacuum in the crank case at the cost of some exhaust smoke. Mechanical and electric pumps are out of the question for this season


Anyone have any direct experience with this setup?


Thanks
