Im wanting to remove the intake manifold to clean it up a bit and paint/powder coat. I have a 98 outback 2.5, i havent seen a how to or anything of that matter on removeing it. The thing im a little nervous about would messing up something on the throttle body (heard they are set and dealer only kinda mess) any one have some input all would be helpful.

Well, you need to drain some coolant for the lines on the TB and IACV, depressurize the fuel system and unhook those, then unplug everything and remove it. Probably an afternoon job.

Depends on what your current level of experience is with your car.
Do you feel comfortable replacing the timing belt or would you say that is a bit over your head?
Removing the intake manifold is a bit time consuming although I am sure it can be done in one evening for a first timer.
You just need to be sure to label all connectors and vacuum hoses. Same with all bolts/nuts that you take off.
The throttle and cruise cables are easy to remove... I havent re-installed them but it looks pretty straight forward.
EDIT****
FYI I have a complete intake manifold with all sensors, injectors fuel rails ect off a 2001 Forester S (2.5L)... Someone will have to chime in here but I am pretty sure it is compatible with your 98.
If you want... I can sell you the manifold itself so that you can do whatever you want with it, then swap it on when you take the other one off... that way you wont have as much downtime waiting for paint to cure ect.
PM me if you are interested.

Thanks for the info guys.
harry: I wouldnt feel safe with me doing the timeing belt if i saw it done maybe once or twice ya. Im one of the guys that can watch it be done once then be ok. Ill keep that in mind i mean its no biggie about down time if i pull it fri night and put it back sunday night or so, but i do thank you for the help.
Anothernord: thats kinda what I had thought was involed just was wondeiring on the throttle body part of it casue of what i had read about the dealer haveing to be the one to set the cables and such.

Phase I and Phase II intake are different... At least the intake I have are... No EGR system on my 01 motor...

Oh... The intake is not that hard to take off. For someone that knows what they are doing it's about a 20 minute job.
The hardest part is the fuel lines and the cooling lines under the intake. You also wanna make sure not to drop anything down the intake ports, that could be a bad day...
Nothing you remove will change adjustments, if you do it the right way. There is no need to remove the TB to pull the intake. I never have on a Subaru unless I'm doing a motor swap or something.
Not as hard as a T-belt for sure, but it would be a good idea to get a manual. A Chilton or a Hanes will work just fine.

from the looks of it I can just unbolt the throttle body from the manifold and lay it to the side right?

they're talking about the TPS on the throttle body, just don't remove that and you won't need to have anyone adjust anything.

If your taking the intake off, then removing the TB is extra unneeded work.

Ok so maybe not AS hard as a t belt... but you need to be familiar with reading service manuals and being meticulous about hoses, sensors ect.

Here's a good tip. If there is a pick n pull around your area, bring tools and pay $2 and you will learn so much there. Does'nt matter if you mess up since its not your car lol. Use the cars there as guinea pigs. You can remove something there so you feel comfortable before you work on your car. The cheapest place to learn unless you have a friend you works on cars

LOL tell me about it. I just started going this year. They have great prices but some are just ridiculous. I suggest to cross reference their price with parts from aftermarket parts from ebay. Some parts are not worth the trip.

You guys just thought of that?! LOL!!! I've been doing that since I was 16! Last thing I wanted to do when I was 16 was mess up parts on my 67 Chevy! Pick and Pull is a good place for self education for sure. The more you play, the more you learn!
Every time I have a dead motor I change out, I take it apart to educate myself each time. I'm almost to the point that I feel I can split a block and put it back together with how many motors I have taken apart.
So yeah, go to a yard for a day, even if it's an old Loyale, you can learn from it. Subaru's are my most favorite car to work on since they are so silmple, but it took me working on them to lose that intimidation factor you have. :smt023

The fuel rail is attached to the intake manifold as are the injectors. All you have to do is unhook all connectors and the fuel lines coming from your fuel filter.
The whole intake, fuel rail, injectors comes off in one piece.

If you could, I'd recommend finding an intake from somewhere and get that prepped and painted/coated. Unless your subie is parked anyways. Don't wanna rush anything!
