The issue was all the vacuum lines were cracked so i replaced them but i cannot figure out where one of the lines go. It is the line going upward from point #2 on the diagram attached. If you can help me figure out where that goes i would greatly appreciate it. The other thing i am contemplating making a secondary air pump simulator to simplify things. If i made one, do all the vacuum lines in the picture need to stay? or i can i remove them without any issue. | | | 04-17-2014, 08:36 PM | #2 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Is the one in question off the hard line? Then it may go underneath the upper intake manifold. At least it does on my M42. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 04-18-2014, 12:55 AM | #3 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | I'm planning on pulling my intake to check/replace the same hoses on my M44 tomorrow. I'll look and take a few pics for you. Ask Johnboyxxx about the simulator. __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!

From what i gather, M44 is a different setup then the M42 because it does not have a secondary air pump but i don't know how different the lines that do run are. And BlackBMWs i would greatly appreciate pictures. I've been trying to get this thing to pass emissions and this one little code is the last thing holding me up. When i got the car the check engine bulb was bad and didn't know. 2 Cam position sensors, intake tubing, gas cap, vacuum lines and and a few gaskets later i am almost done. | | | 04-18-2014, 12:56 PM | #5 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Quote: Originally Posted by smiller6120 328ti, it's off of the T-fitting, but the hoses are all rubber vacuum lines and sits underneath the lower intake.

The M42 doesn't have the t-fitting. Thought you might have been talking about the other hose. And yes, they don't have the secondary air pump. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 04-20-2014, 05:26 AM | #6 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Quote: Originally Posted by smiller6120 And BlackBMWs i would greatly appreciate pictures.

I recall when I swapped motors a vacuum line going down and looked at the diagram for the fuel. Hose 16. http://www.realoem.com/bmw/showparts...30&hg=13&fg=10 I hope you locate the other end of the t. I believe the other end of the t goes to the intake manifold. Good luck!

There was a cap covering the vacuum port on the TB and i didn't think it went there as the cap looked like it had been there a while and was factory. Finally my SAP code went off. | | | 04-25-2014, 06:40 AM | #8 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Quote: Originally Posted by smiller6120 Thank you for your help.
