oil leak
Just bought this car, it has a vortech supercharge. It didn't have a pcv so I put one and hooked in to the tb. Firstwant to know if its connected to the right place. Second I think it was building alot of pressure that oil is leaking between the lower intake and the block, on the front and back. Can not having a pcv cause it to leak or probably some thing else caused it. Don't want to think that it coming from the heads gasket.I really need the advise. Also need a good mechanic to do the work in the houston area. Would like to do it my self so I can learn but im working 12 hours 6 days a week.

first your pcv valve gets hooked to your upper intake manifold make sure you have the pcv filter as i am finding out now, also yes not having a pcv valve can cause it to leak i would replace the lower intake gaskets though.
as to why it causes leaks is because it cant release the pressure so it pushes oil out where ever it can

PCV is Positive Crankcase Ventilation. It's a smog device, to suck blow by gasses out of the crank case, and run them through the engine again. It requires vacuum to operate correctly. I'm not an expert with a blown engine, But I would think that hooking the PCV line to the TB would pressurize the crankcase. That's a bad thing. Probably why it was left open by the previous owner.
If you really wanrt to use is, Put it in the intake side of the blower, so it see's a vacuum. But, if you can get away with it, vent it to atmosphere via a catch can or air/oil seperater.
