Oil catch can to intake

I don't understand what it was saying about oil contamination. Is it saying you can contaminate your pistons if you have the catch can going to the intake or if you don't

If it needs to be hooked to the intake to relieve pressure and stop contamination I think I'm going to build one like this.

Anyone have any thoughts on the benefits of the oil catch can having vaccum coming from the intake. Most catch cans seem to just have a breather but this doesn't give a vacuum just relievs a little pressure. Someone said that with a vacuum it relieves pressure from the gases/fumes the head or engine produce at high rpms.

Damn good find Kanuck. Will deffinately work. More invoved, but will work.

The catch tanks that have a breather on them are intended to be used on an engine that have some means of crankcase evacuation other than the intake tract such as a vaccuum pump or valves in the exhaust. The correct type of catch tank if you are going to keep it tied into the intake tract does not have a breather.

Right.

Mine now has a breather but that doesn't give any negative pressure it just gives the crankcase more room.
I think I'm going to top off my breather with a cap and have a hose connect to the intake.

Makes since that you could contanminate the pistons without sucking out the fumes/gases.
