Hey guys,

I am having an issue with my car that I think is the result of insufficient crankcase ventilation (it's a 2.4L with a FP GT3582R).

My setup is as pictured:

Basically it's just 2 lines, one from the PCV and one from the valve cover to a vented catch can. I'm getting hardly any blow by (driven it 600 miles and only got a teaspoon in the can) but have a lot of pressure in the crank case.

I had to put a spring on my dipstick to prevent it from shooting out (a common issue, I know) and now oil is coming out of the oil fill cap, dripping onto the valve cover and eventually burning off. The result is that I'm burning a noticeable amount of oil from there and not only does it smell, but it worries me that I will run it low (a long shot, I know).

Could my issue be insufficient ventilation? Would -10AN to a catch can be beneficial? What have you all done on a setup like mine? I'm flowing 58lb/min at WOT right now.

I'm very green to DSMs but have a little understanding when it comes to PCV systems.

Thanks.
