K&N Intake issues
I've been working on getting my jeep engine dialed in, and theres a few things that concern me that I'm trying to work out. First and foremost, my K&N intake. Ever since I put it on, I have noticed the sound is... interesting. It doesn't sound like air being sucked through a filter, there is almost a metal on metal grinding sound that comes from it. It gets louder as you accelerate. I have checked out multiple jeeps with variable intakes and they all seem to have the same "air being sucked through a filter" noise. Mine has a grind that I can't put my finger on, and does not sound like it should be there.
IAC, CPS, TPS all replaced within the last year. Engine has good oil in it. There does appear to be quite a bit of oil slung around the bottom of the jeep and has a noticeable amount of oil built up around the bell housing. Plan on getting all new seals eventually, but wheres the best place to start? Thinking the main seal will be first, but what would the list of things you would do to your engine to get it "up to speed," and the best order to fix these issues in.
In case it helps: K&N intake, Magnaflow cat, magnaflow muffler (Not as "jeepy" as the flow master super 40 was, i miss it)
