Thanks on clarifying the breather to air filtration. Blow by what i meant was while driving i noticed smoke not blue oily smoke more whitish coming from the rear of the car I pulled over when i could and then noticed a ruff idle as well thinking i may have had a water leak i popped the hood no water leak little more oil than usual on top pan rim not a lot but a little. restarted car sluggish start to ruff idle limped home did some research quickest cheapest was check the PCV it was making the clicking noise but would sometimes stick i cleaned it with a squirt or two of break cleaner took it for a ride fired right up ran smooth no smoke at all ( i will replace the PCV ). thats when i read the 2.25 exhaust was a benefit. 91XXXmiles just looking for ways to minimize this from causing me extra money down the road. and thanks for your reply:thumbsup:
