I,m looking for the name of a hose that comes off the throttle body pipe that goes to the crankcase on my 2003 9-5 2.3t?

Crankcase ventilation system is used to consume crankcase vapors created during the combustion process instead of venting them to the atmosphere.
Fresh air is supplied through a filter to the crankcase, the crankcase mixes the fresh air with the blow-by gases and then passed through a positive crankcase ventilation (PCV) orificed tube into the intake manifold.
The PCV orificed tube restricts the flow rate of the blow-by gases using a 3 mm (0.118 in) (a) orifice located at the end of the tube. If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow-by gases to back flow through the crankcase vent tube into the throttle body in order to be consumed by normal combustion. Positive Crankcase Ventilation Hose/Pipe/Tube Replacement
Remove the two nuts (2) from the fuel injector sight shield (1).
Lift the sight shield (1) from the front and pull forward to disengage the rear tab from the bracket.
Disconnect the PCV fresh air tube from the left camshaft cover.
Remove the PCV fresh air tube from the throttle body.
Remove the drive belt. Refer to Drive Belt Replacement .
Remove the power steering pump retaining bolt.
With the hoses still attached, Carefully position aside the power steering pump.
Remove the retaining clip securing the PCV dirty air tube.
Disconnect the PCV dirty air tube from the PCV orificed tube.
Remove the PCV dirty air tube from the intake manifold.

Look for big black tub goes to intake should be onside,near RPM cable.

You will have to get the bracket out of the way, just to get the housing off and back on in an easy manner that won't cause a leak.
The hose may be the one from the valve cover area, carrying the blow by and crankcase fumes back into the intake-so part of the positive crankcase ventilation. So that hose could have a lot of carbon like deposits. See if you can twist or work it back and forth carefully. Not sure how it connects or where it comes apart, If it is plastic, sometimes they break no matter how careful- age makes them very brittle.

hello
if you locate the airbox fitted to the Right hand inner wing you will see a large black intake pipe leading to the centre rear end of the engine bay that is where the throttle body is located if you remove this pipe by removing the hose clip securing the intake pipe of the air mass meter and then follow the pipe back to the centre rear of the engine bay and the pipe is attached to the throttle boy with 2 10mm hex bolt once these bolts are removedand the intake pipe is removed the throttle body is evident

under the exhaust pipe where the upper radiator hose goes to the engine. Not exactly an easy/quick fix.

in your car the air ventilation system is freeze up causing a build up of pressure which caused the oil to burst out. there is the mosture sludge build up under the oil fill cap . its advisable to clean everything up and then check out by starting the car. also spray crab cleaner in the throttle body and check out. as per me the problem is causing because of :-- I guess the breather vent tube was full of oil - frozen in there somehow. Must have to do with that sludge buildup on my oil fill cap. This is the one coming off the front on the left side of the oil filter. It goes down under the engine. This blockage caused a pressure buildup in the crankcase which caused oil to blow by the pistons and into the combustion chamber and out into the air intake hose and throttle body. get the spark plugs removed and cleaned up all the oil. The reason it sputter is because of all the oil in the combustion chamber. No air could get in. get the oil change and insulate the breather pipe in case of future freeze ups. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

drain the coolant
remove the 2 connectors on the air duct
remove the air inlet duct from the throttle body to the air box
disconnect the throttle cable and cruise control cable
remove the throttle cable bracket one 10mm nut at the bottom of the throttle body and 2-10mm bolts on top of the throttle body
MOVE A SIDE YOU DO NOT HAVE TO REMOVE THE CABLES FROM THE BRACKET
ok there is a coolant pipe runs across the front valve cover
remove the the hose that will go under the upper intake
then remove the 8mm bolt holding the coolant pipe
then back at the throttle body there are 2 small hoses side the clamps up the you will see a brace on the coolant pipe bolts to the throttle body with a 13mm nut remove that nut
ok now the 2 small hoses will be stuck to the pipe use a SLIDE A SMALL SCREW DRIVER BETWEEN THE HOSES AND THE COOLANT PIPE BE CAREFULL NOT TO CUT THE HOSE
now lift the coolant pipe up at the front of the engine IT HASE AN O RING SEAL
then slide the coolant pipe back at the throttle body back to remove the hoses from the coolant pipe
remove the TPS,IAC and EVAP connectors
then remove the 2 thottle body bolts 13mm
remove the throttle body
you may have to TAP THE THROTTLE BODY WITH A SCREW DRIVE HANDLE TO RELEASE
check the gasket make sure it didn't TEAR or REPLACE IT
now remove the hose to the thermostat housing
there are 2 -13mm bolts the top bolt take it out
the bottom bolt remove 90% the bottom bolt hole is slotted
remove the thermostat housing
REV. porcedure to reassemble
then after you have reassembled
OPEN BOTH BLEED SCREWS THEY ARE 7mm BOLTS one on the thermostat housing and the other one is on the coolant pipe
fill the cooling system till you have a STREAM OF COOLANT COMING OUT OF THE BLEEDERS now CLOSE THE BLEEDER SCREWS
top up coolant in rad and install the cap top up the over flow bottle
start the vehicle up and select VENT,HIGH HEAT BLOWER TO HIGH
let vehicle run untill you have GOOD HEAT COMING OUT OF THE VENTS HOT! NOT JUST WARM
this will insure you have no air locks in the cooling system
good luck and i hope this was helpfull

It's located in the intake manifold under the throttle body, Follow the radiator hose from the drivers side to the engine. The hose is then connected to the thermostat housing which goes under the throttle body and behind the exhaust pipe. 
if you have small hands and the right tools you can get it out with out disconnecting the exhaust pipe or throttle body. 
Good luck and i feel the pain. Keep me posted.

Drain coolant at the radiator drain. Remove air intake hose and MAF sensor assembly. remove throttle cable bracket and disconnect cable linkage. Remove throttle body bolts and disconnect coolant hoses to throttle body. Loosen heater hose pipe and remove heater hose from rear of pipe. Remove radiator hose from thermostat housing. Remove top thermostat housing bolt. Loosen and almost remove lower thermostat bolt. You will need to slide your wrench and hand under the exhaust crossover pipe to gain access. Loosen the bolt until you can remove the thermostat housing, it should be slotted to clear the bolt. Replace the thermostat and reassemble. Bleed cooling system using the two bleed screws (one on thermostat housing and the other on the passenger side of the engine where the heater hose pipe comes out above the water pump.

i would start by cleaning out the throttle body. they collect soot and not have to be a lot either for it to mess up the idle speed, i had trhis on mine soon as i dipped the clutch to slow down the rpm dropped to about 400 to stall, i cleaned throttle body out ( taking air intake off and wipe round inside and the butterfly will be enough) and now it idles and the rpm dont drop below 900
