So I started this today and took pics along the way. As far as the parts # for the hoses your better off looking here http://bmwfans.info/original/E30/2-T/318is-M42/USA/L/M/1991/04/mg-11/ill-11_1272/

Special tools?
I didn't have a 11 mm deep socket for the intake manifold
Other related parts?
throttle assembly gasket (2x)

Take off the throttle cable. You need to be careful since the rubber is hard and brittle.

Air hose
(http://i25.photobucket.com/albums/c57/m42sport/318is018-2.jpg)
Theres a C shaped bracket under the opening of the throttle assembly that needs to be unbolted to access the 4 nuts that attach the throttle assembly to the intake manifold
(http://i25.photobucket.com/albums/c57/m42sport/318is019-1.jpg)
Undo the 4 nuts that hold the throttle body housing to the intake manifold. you need a 10 mm long socket.

Once you undo the coolant hoses on throttle warmer? Get ready for more coolant flow from the drain plug
(http://i25.photobucket.com/albums/c57/m42sport/318is025-2.jpg)
Now remove the intake manifold. They are held in place by 11mm nuts! So you need a long 11mm socket. Also there is a bracket on each end of the intake manifold that holds it inplace. Sorry no pics
Also this bracket
(http://i25.photobucket.com/albums/c57/m42sport/318is003-5.jpg)
After the intake manifold is out, you need to take out the lower portion of the manifold. there are 5 nuts. Here I already loosened it and moved it out of the way.

all the connection were brittle and cracked. I did not order this part so its gonna set me back a couple days.
Ok so got some new parts today!

Nice pictorial writeup... what is that white/blue L connector you have on your vacuum line? That line goes to the booster???
-
I made the same mistake. Pulled the plastic coolant junction out and most of the plastic stayed inside my old coolant hoses. Great pics!!
This is sticky material
-
Thanks I'll keep updating when my parts arrive. Also, after this I'll think about tackling the timing chain with a writeup also.

You mean this one? I don't know. The clamps look original so I don't think its ever been messed with.

Mine has something similar. its not colored blue.. its black plastic on my car..
-
^It's clearish plastic on mine... It's blue/white on a different m42 e30 I looked at the other day so I was wondering. I'm trying to look at everything possible to find the cause of my start idle problems.
-
My idle was a bit irratic when I was stopped at a traffic light. Most of my air hoses were cracked and loose fitting so I replaced them. I guess I'll find out if I fixed the problem once I get a chance to start the car.
-
Finished it hoses up today.
(http://i25.photobucket.com/albums/c57/m42sport/318is008-7.jpg)
hooked up one end. I'm pointing to the same hose here.
(http://i25.photobucket.com/albums/c57/m42sport/318is010-6.jpg)
Hooked up one end of that u pipe with the 50 hose fittings!
Sorry didn't take a pic of the middle attachment of the waterpipe. It goes to the radiator around the drain plug.
(http://i25.photobucket.com/albums/c57/m42sport/318is009-7.jpg)
new lower intake gasket
(http://i25.photobucket.com/albums/c57/m42sport/318is001-7.jpg)
Connected this hose from the edge of the engine block to the bottom pipe on the firewall
(http://i25.photobucket.com/albums/c57/m42sport/318is002-5.jpg)
Already showed you where this hose comes from.
(http://i25.photobucket.com/albums/c57/m42sport/318is011-7.jpg)
Now mount your lower intake manifold.
(http://i25.photobucket.com/albums/c57/m42sport/318is012-6.jpg)
pull these two pipes out the opening.
(http://i25.photobucket.com/albums/c57/m42sport/318is013-3.jpg)
just showing where the hell this hose is coming from
(http://i25.photobucket.com/albums/c57/m42sport/318is015-2.jpg)
this is what the mess of hoses should look like
(http://i25.photobucket.com/albums/c57/m42sport/318is017-3.jpg)
got a new air hose under the intake boot.
(http://i25.photobucket.com/albums/c57/m42sport/318is019-3.jpg)
Mount your intake manifold and reattach this bracket
(http://i25.photobucket.com/albums/c57/m42sport/318is020-3.jpg)
attach your ICV and attach the longer air hose to
(http://i25.photobucket.com/albums/c57/m42sport/318is021-3.jpg)
the U shaped hose.
(http://i25.photobucket.com/albums/c57/m42sport/318is022-3.jpg)
connect ICV wire
(http://i25.photobucket.com/albums/c57/m42sport/318is024-3.jpg)
tighten bracket
Mount your throttle assembly. Sorry no pics. Dont forget to reconnect the water hoses to the throttle warmer (?) or whatever that part is called.
(http://i25.photobucket.com/albums/c57/m42sport/318is027-1.jpg)
remember that C shaped bracket on the lower half of the throttle assembly? well its there to hold the lower half of the throttle warmer to the throttle assembly.
(http://i25.photobucket.com/albums/c57/m42sport/318is029-1.jpg)
then reconnect this bitch of a air hose.
(http://i25.photobucket.com/albums/c57/m42sport/318is031-1.jpg)
Then the throttle cable. I might have missed a connection or two in the reassembly...refer to my dissassembly pics. BTW anyone know the part # for these two parts? Both were crusty and brittle and are falling apart. Thanks.
-
Well documented write up.
-
Damn man you are very detailed! I always forget to put the surgeon gloves on when i work on my car.. i have a huge box of them that i always forget about

Nice write up but this is all incredibly pointless and expensive when you can bypass the mass of hoses with a single 9" piece of coolant hose. Mine just passed visual inspection part of smog check in California without any of this stuff. The tech said they don't care as long as nothing is leaking and all the emissions components are in place and functional.

Its a one way valve to maintain vacuum in the brake booster in case the engine shuts down.
Maybe this is a good time to clean out your throttle body.
good luck

If you're referring to the grommet where the cable passes through the bracket..
Grommet
Part number: 35 41 1 152 744
The clip where the cable attaches to the TB actuator arm (?), I'm still searching for.. I needed both pieces, myself ;)

It only cost me ~50 dollars for every single hose under there, and it looks very clean TO EACH HIS OWN :confused:
-
^I prefer it deleted as well, but lots of ppl keep them original. Which is cool too. I just didn't like the way the original stuff cracked and corroded out. The less points of failure the better in my book.

Thanks. I figure this will help someone else so why not document as I go along.

Yeah I sprayed it down with brake cleaner before reassembly.
-
wheres the bleeder screw located?
-
On the driver's side of the radiator... don't put too much torque on it, they break really easily.

Ok thanks.
I like to ring the guys neck who allowed this hose into production. As you can see the hose opening is clearly too small to fit on the radiator. I spent about 30min trying to muscle it in. Lets see how long this will hold!

hey I should've put this the writeup section.
-
Nice write-up and pics. I don't necessarily think this vacuum / cooling system is not good. I just like not working on it, and not looking at it. Make sure to tighten your hoses. ;)
-
Haha that's funny someone else noticed the hose connector problem! I ended up cutting the old hose (which was still in good shape, at least on that end), and splicing old and new together right under the airbox. That solved my connector problem, but it pissed me off that I had to do it.
I too like having things oem. That's how I did mine when I did it a year ago. Nice write-up! Brings back memories.
-

I was thinking that maybe the vacuum hoses crack so often is that they are being heated beyond what they would normally be by the hot coolant running through the throttle heater hoses. The vacuum lines run right next to them in those 4-way hose junctions. I'm using oem replacement vacuum hoses, but deleting the TB heater mess, so I guess I'll find out depending on how soon they crack again.
-
You have two hoses reversed, the little stubby hose that connects to the nipple on the bottom of the throttle body needs to go to the crank case vent, not the icv. There is a reason it is angled backwards, as air moves by the hole it will create a vacuum thus relieving the pressure in the crank case
-
nice write up, good pics
i too dleleted all that stuff, but good write up all the same. this is also a good time to setrvice the icv valve. there is a write up on it someplace, but its simple, basically just shooting carb cleaner through it a bucnh to free up the slides, as they will get full of junk from vacum, and stick, causing idle issues
and yes hat stinking hose to the radiator is a nightmare, even got mine from bmw as I did not think the aftermarket one was good, ends up the bmw one was just as bad/tight
so I heated mine with a hair dryer, then put some oil on the nipple of the raidator, adn slid it on, not easy, but easier then when it ws cold
another britlle piece is the throttle cable adjusting nut
and like mentioned above the big black plastic pipe
also a good time to replace the injector seals, or the injectors themsleves.but thtas a whole other issue and expense
but you saved money by doing the delete so you can afford the injector seals (http://www.m42club.com/forums/showthread.php?t=2742
which of course can lead to different better injectors
if your not aware of that one, its a different write up, but better fuel atomazation, better gas milage, and better throttle responce and better idle, my 4 upgrade bosh injectors with seals cost me $80 ( for all 4)
I look at it like this.....the car is 20+ years old, if this piece of rubber or seal is going, the others are not far behind, if im right there with the parts in my hand , Ill replace them,
nothing sucks more, then redoing something a month later

do you know a good site to order all those parts?

Sorry to bump an old thread. Can somebody please help me pointing where the other end of these 2 hoses are connected? A picture would be great. Please note I did not do the mess under the intake thing. Thanks.

I got lucky and found you a "before" shot. If you draw a line (on your picture) from the yellow #2 to the yellow #1 you will see the opening of the hose that #2 connects too. Should be a plastic 90 there. #1 goes down to the Check valve on the Carbon Canister.
(http://i361.photobucket.com/albums/oo57/rjcaptsbmws/Photo0294.jpg)

Thank you. Would you know where is the other hose on "90 degrees elbow" connected? The hose that goes underneath the intake manifold? Realoeam doesn't show a clear picture where it is connected. Thanks.

It snakes under the intakes and toward the front and comes up and connects to the valve cover. In your picture, you can just see it directly to the left of the intake manifold.
