Intake manifold dirty, how should i clean it?

As stated, my intake manifold is dirty. Seems to have some oil in there as well as sludge buildup along the sides. Im young and haven't the experience to know if this is normal in vehicles, or if it is cause for concern and I should clean. Is there any good ways to clean it besides removing and just spraying it with carb cleaner?

I'm assuming your speaking of the inside?Unless you want to do it the best way by pulling the intake, then all you can do is purchase throttle body spray cleaner and go at it.

You need a can of throtle body cleaner, rag, Q-tips, screwdriver, chair, and a beer. Remove the throtle body from the motor and clean it. Takes about 15 minutes so you might need more than one beer

He said he was young. He may have to wait until he's 21 to do the job

do not use carb cleaner, Throttle body cleaner only. Sea foam works good too. Crank the car and wait about 5 mins then pour into intake, at first you will think you just blew up your car because it will smoke like a Cuban with a cigar but it will do its cleaning job and make you Jeep run a lot better.

I actually already seafoam'd it last week. I didnt get much, if any smoke. It was more like someone smoking a cigarette at best. But I believe that is because my CAT may be clogged, which is a another project another day. Right now I am checking my exhaust for leaks first, which is why my intake and exhaust manifolds will be off.

I also removed everything I could off the throtle body to help get into all the little holes.

Im talking about the intake manifold.... not the throttly body. Its definitely not a ten minute job to remove that and clean it. Taking the throttle body off is a piece of cake.

Anyway, does everyone else have their brake lines (i think there brake lines) sandwhiched between a piece of sheetmetal that is bolted into the bottom of their intake manifold? I have this twice. These bolts are 9 mm and are stuck pretty good. Broke 1 socket adapter already and neitheer are even loose.

Also, anyone know what http://www.dailydriventj.com/images/mfr/43.jpg that is? the guide im using [Repair] Exhaust Manifold Replacement Guide says on step 12 to undo these bolts. I couldnt find them...
