Totally Dissapointed!!!!!
Depending on how well it idles, some shops will say lose the PCV, as it's adding oil vapors and that it's a vaccum leak on an engine that doesnt need the help. I disagree, and always run a PCV. I havent gotten to the level of needing an evac system, but I'm sure eventually I will. All PCVs are not the same iether. If the one you have really hurts the idle, a smaller oriface one will lket it idle better, and does much the same amount of pressure relief. The hardest one I ever wroked with is a stroked 2.4L Toyota with a hybrid turbo in a 4wd truck. It idles very roughly, and I had to buy 3-4 PCVs toget the best fit. If it's not stock, a stock one may not be what you need.
