Is there an after market site for all vacuum hoses or do I have to go to the Dealer which is an hour away ??
-
Get the part #s and order from BMA, Bavauto etc. I imagine the dealer will rip you a new one on pricing as usual.

i've had a decent bit of trouble locating all of the part numbers for the vacuum hoses...either that or this isn't that many hoses to begin with!
I sent patrick an email requesting that he look up the part numbers for me.
I gave him a huge list of stuff...:D

Well, half the things that break are connectors, not hoses.
Let's see here. On http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=11_1272&hg=11&fg=35 (http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=11_1272&hg=11&fg=35)
parts # 14, 15, 17, 25
On the air flow sensor page http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=13_0307&hg=13&fg=15 (http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=13_0307&hg=13&fg=15)
parts 11 through 17.
On the Cylinder head cover page http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=11_0264&hg=11&fg=15 (http://www.realoem.com/bmw/showparts.do?model=AF93&mospid=47305&btnr=11_0264&hg=11&fg=15)
parts 10 and 11.
I think that's about it, but I could be wrong.

i ordered all of the hoses from the first link...i was doubting that any of the part numbers there could be vacuum hoses because its found in the water hoses section..
i guess that might be all of them?
Thumper bought a set from a local dude...maybe he has some p/n's..
-
I copied this from another post - forget where. I have used cloth braided fuel injection hose for some of the small water lines like #'s 11, 13, and 16 from the head to the throttle body heater plate. They're about $30 from the dealer. $2 a foot at the parts store. #14 is an inch long and costs $6! (http://www.m42club.com/forums/attachment.php?attachmentid=381&d=1156043563)

FWIW the red quetion mark area is connected to the charcoal canister. I seriously HATE this part of the m42 as it was severely over engineered. I'll take a pic of my by-pass this w/end and post it up.You save a couple of $$ as u dont order useless hoses.
-
while we're on that diagram..

does anyone know what the part number for that?! i broke mine when pulling it out of the spare motor.
-
11531717620 $30.13
I also have thought of eliminating the siamese hoses and using reducers to duplicate the ones change sizes. I don't really see a reason to pay $$ for hoses that can be duplicated with off the shelf items for about one fourth the cost.

Yea , they got some odd ball stuff under there that's for sure.
-
it lists part number 11531717620 as # 2 in the image..
that looks like the lower radiator hose.
are you sure thats it? the piece im talking about comes out of the block right by the alternator or by the left engine mount.
-
Always on the lookout to save a buck, I came up with the following. I hope it's right and if not someone will be in the know. I divided the maze of hoses into circuits:
1) Out of the head and through the throttle body heating plates and back into the lower thingie into the radiator.
2) Valve cover to throttle body.
3) Idle control valve to bottom of intake bellows.

The diagram makes it look more confusing than it actually is. I wish I took a pic of my setup.
:::Valve cover to the Throttle Body - 1 standard hose with a connector.
:::Out of the plastic coolant pipe straight to the head. - 1 Standard hose from BMW which has 2 different sized ends. Due to the bend I used a coolant/hose tape from HD to seal it as the factory mold doesn't like to be bent awkward. It will leak if you don't do this. I learned the hard way.
::: Intake bellow to the ICV - 1 hose
::: Eliminate spaghetti junction of hoses under the intake manifold, they all serve as an intake and exit for routing the coolant flow for the throttle body. You can remove the adapter plate and the pipes.
All this you do at your own risk. I'll try take a pic of what it looks like assembled :rolleyes:
-
What is the purpose of the heated plates around the throttle body and what effect does removing them have? It sure makes that mess less complicated. Couldn't the head outlet and the lower inlet simply be capped off if the plates are redundant?
-
The coolant running through the heater plate prevents the throttle body from icing in severe cold. Some have stated it's related to emissions as well. I deleted in on my m20 as well when I lived in NJ as they have a cork gasket which is actually a major PITA when it goes out on the 6 cyl cars. I have done this mod on one m20 and 3 m42s and never had issues with my throttle sticking or not being able to pass emissions.
You can cap off the entry and exit for the heater plate as well. That's what I did on my other car. This time around I decided to eliminate everything related to that mess.
-
I just got through puting the intake manifold on my car and had none of the coolantlines or vacuum lines and ended up building what I needed from good scraps.
Just like dclay said, three circuits. The P.O had capped off the coolant ports on the block and coolant pipe. I made the throttle plate heater hoses in two pieces so I could disconnect those in the middle and pull the complete upper intake off as a unit without a lot of hassle.
I guess it's nice to have all of the original stuff, but it did seem to me like there was way more pieces there than necassary. The one hose I bought from the dealer was the one that exits the heater pipe up top and goes to the throttle plate heater. It's tapered. I went to the junk yard and pulled coolant and vacuum lines off of a bunch of BMWs and VWs. Got a whole garbage bag full for ten bucks. Just used a rag and some WD40 to clean them up and make them look new. I paid more for the new tapered hose by itself. A couple plastic elbows and a razor knife and I had a nice tight fitting discrete install. Its amazing the shapes and bends you can find. Some of these hoses were probably 20 bucks new.
While I was poking around on realoem I saw that you can get short throttle studs for the intake manifold that are for "tropical" use. Specifficaly for the throttle heater delete.
-
A couple of years ago I had an Impala SS. One of the "free" mods on that car was to bypass the coolant lines to the TB. Everyone claimed it was worth ~5 HP. I'm not so sure I belive that, but I am sure that anything that makes that maze of hoses simpler can only be good.
Also, fwiw, most piston engined aircraft have a carb heat feature, in the form of routing a small portion of exhaust around the carb to prevent icing when desired. I can tell you from experience that applying carb heat results in a loss in power. Of course, it can also keep your aircraft from an embarrasing "unplanned forced landing".
Apples to oranges, I know, but the same principle.

Sadly our cars don't gain any hp from TB coolant line delete (not that I have noticed in my past experience with the m20b25/m20b27 and current m42b18) processes.
Here are some pics that show the set up I have. One car still has the TB heater plate (capped off at the bottom) The "u-pipe" you see is the stock pipe modded to allow coolant to flow out of the plastic feed pipe and then back into the head. If I have read what most of you have said correctly - it is possible to totally cap both the exit point from that plastic pipe and the feed into the head of totally?

Second set of pics show the heater plate delete. Notice the longer studs look goofy :rolleyes:. As mentioned above you can get shorter studs. Sorry for the dirty pics. I haven't had time to pretty up the engine bays in a while. :D

If you want silicone hoses ima give these a try

I like this thread ... I'll be tackling this job shortly and the silicone hoses look like the way to go. Bimmer, have you used the product you listed?
-
not yet but im going to order them tomorrow and try them. but i know silicone is way better then rubber ill be getting some blue hoses so you can see where there at. i just think silicone is more reliable then rubber
-
I talked to them a while ago about the M42, I'm glad they finally went with a kit for us. Let us know how it works out - post some pics too - I'm planning on the same thing sooner or later.
-
of coarse i will
-
Any news on this? Pics Bimmer! We demand pics!
-
I just ordered a set of red from Hiperformancestore.com ... Dave I'll be looking you up if I have questions.
-
hey sorry im kind of holding off on the hoses for a bit due to that had new tires put on my car and im short on money but ill will get them soon and post pics. sorry about that
