Oil problem**Update**
I have an oil hose problem. As seen in the pic attached, there is a hose that runs under the intake and connects to something. I can't see the other end. My question to you folks is: What needs to be removed in order to replace the hose?
TIA

You almost certainly have a strong smell of oil fumes inside the car and oil mist over the left camcover.
Your missing hose is a breather and is in parallel with the similar one with the hose clamp on the extreme left of your picture. IIRC they connect together below the airbox. Pull the airbox and see if the missing hose is still there. With luck this might be an easy one.

The breather hose that always goes first, to replace you can either take the intake off or try and remove the thermostat housing which will give you the required access also.

Chris . . I figured either or. What's easier? Either way it's got to be fixed. Oil is all over the place. I've run through a bottle of simple green already just cleaning the inside of the hood. If I go the T-Stat route, what gaskets will I need?
Thanks for your help.

Schocki . . It does but it look like the T-Stat housing has to come off. I was just outside looking at it again. If I take off the intake, I can clean & replace other hoses WIAT. Removing the intake looks like a whole lotta fun.
Thanks for replying.

Ron, Schocki's right:
To replace that hose you will need to get the intake 'lifted' up or go through the front from the coolant cross-over. However, IMHO, you cannot get the x-over out without lifting the intake. YMMV. And doing it from the front is going to be a lot more messy.
To lift the intake, you'll need to pull the fuel rails, and unbolt the intake. You don't have to remove the other hoses. You will need to disconnect the 'non-intake' end of them. Once you can move the intake up about an inch or so, you will be able to get to the back-side of the filler neck.
Be careful with the vacuum lines, and harness connections to the MAS, throttle switch, knock sensors, etc. If you disturb them too much you'll be doing the full Intake Monty.
My intake R&R tech article on the OC website has step-by-step instructions.

Ron,
I would let the engine cool down and use engine degreaser to clean it. Let the degreaser sit a little while and spray the engine clean with a water hose. I always start the engine and let it idle while I'm cleaning it with water. Make sure not to spray directly on elctrical connections and use some engine detailer afterwards.

I heartily recommend removing the intake, replacing all the hoses, replacing the knock sensors, cleaning your rotary idle actuator, testing your WOT and idle contacts, cleaning the Vee of the block, replacing the vacuum elbows, having your injectors balanced and blue-printed, replacing the oil filler neck gasket, replacing the intake-to-head gaskets, the 10 intake bolt rubber pressure gaskets... When you're done your beastie will run like a new car (unless there's something else wrong of course...)
It's just a question of how deep you want to go and how much you want to spend on rubber bits. I was - perhaps incorrectly - assuming you were looking for the least-intensive means of getting that breather fitting connected.

It may very well be that the manufacturing of my intake and crossover resulted in pieces that were a little too 'over-size.' Or that I lacked appropriately-weird tools for the job.
In the end, and since I've gotten to the point were I can remove a 32v intake with my eyes closed in about three hours, I just decided it was expedient to spend the hour to get the intake up and back by the inch or so necessary to get to the back bolts on the x-over and to get the 'feet' of the x-over unlocked from the 'feet' of the intake.
So, I'm not saying it cannot be done - just someone who's BTDT should post.

Dave . . I don't mind spending as long as it saves me from doing (almost) the same job twice. Call it a clean sweep, rather do it now than later blah blah blah. I just want to "gitter done".
