Got's the 01 S40 with 148k miles, with 3 inch aluminum air intake injen dry filter, 3 inch cat less down pipe to 3 inch exhaust with one free flowing cat and injen muffler. Sitting on the H&R lowering springs, big mistake! Should of went with the coil overs for sure, oh well. Silver paint with black carbon fiber wrap on the hood and trunk, blacked out stock wheels and windows with a low windshield brow. Oh yeah, and trans cooler which solved the shifting issues.Any how, recently replaced the pcv system with the IPD kit. Still getting a bit of oil by the new ipd fill cap. So that got me thinking about doing a oil catch can. Seems like some are for it and others think its a bad idea.... just like the air intake, which by the way was well worth the hassle! Has anyone done the catch can? Any thoughts or first hand experience would be greatly appreciated!

 

Just did a catch can deal on my 07 s60, no more blow by and seems like best idea against pcv

 

Looks good! Where in the pcv system did you loop it in?
