yea, please, no splitting of lines.

When mango gets like this, it's best to just do what he says!

In terms of the hoses behind intake mani...you can see pictures of that in my 'intake manifold' thread. I think flashtwosix posted some pictures of her intake mani setup for me...might help you...but you don't want to randomly connect or plug stuff up.

Take your time as mango said. Although he's a fruit, the mango is probably among the most sophisticated...right up there with kiwi, I think.

I would get the F-connector line going to the correct place by itself first. Then you will only have 1 thing wrong. I would then find where the cylinder line is supposed to go to, though it probably doesn't matter since that exhaust valve isn't really needed anyway. Mine doesn't even work anymore, though maybe the PO golf teed it.

Like I said it isn't needed--you are right about that. however the other end of that canister plugs into the manifold. If that port is not sealed, you will be taking in unmetered air (vacuum leak) so it needs to be dealt with correctly. DMAX i am not sure the 323/328 comes with that exhaust flap so i am not sure your manifold pictures would show where that line goes.

i'm sure that info is out there somewhere.

Yeah, unmetered and worse, unfiltered air.

Quick question, as someone who is converting his fuel filter from the external 3/2 way valve to the internal FPR found in the M54 Filter, what material is the vacuum line made out of and can I source it at a hardware/ home improvement store? I already have a Meter of the rubbery vacuum line needed to mate the lines to the F-connector and the FPR nipples just looking for the harder line for less than dealer cost.

I am in possession of the Filter, F-connector, Fuel Rail and the 24#/hr injectors.

Thanks all, I will follow that advice and hopefully I can find the missing plug! If anyone does have links to the schematics of the intake manifold for my car (2001 330Ci) that would really be great, otherwise I will try and track them down and/or break out the mirror and try and look at the rear of the manifold!

If I come into contact with an E46 engine this weekend, i'll try to trace the line and find out where it goes. I think i may even have pictures of an M54 outside of the car that might show where. I'll do some digging.

Bavarian Autosport lists that part for $29. Probably cheaper at some of the other mail order places. 13327561060.

323/328 have no exhaust flap. No extra vac canister. The only vac lines behind the manifold go to the SAP valve by way of a one way check valve.

That would be awesome if you do Mango, it's always easier in my head before I actually start looking!

If you happen to have any links to those pics it would be great... tried searching under your username and "intake manifold" and you've got over 100 threads posted on! Thanks again for the help regardless!

ECS has an assembly for it. That's a bit pricey though. It's more of a plastic than a rubber material, though it's still fairly flexable.

Okay that is not bad. But now I actually think that the vac line on the 3/2 way regulator is the one that runs up to the Fuel Rail on the M52tu. Was underneath it today getting my feet wet before I dive in tomorrow.

Follow up with part# 11611727176 for the manifold plug (from the E39) and part number 51712258519 for the body plug after removing the line from the body of the car..

I don't feel the need to "delete" it unless you think it would be a good idea? Also, now that the cold weather has hit, it is very obvious that my car is quite "jerky" when it's cold, having degrees of lack of power followed by a snap back to power and so forth. Could this be the result of a vacuum leak? The only other thing I did other than replace the fuel filter was to check the DISA valve. Doesn't seem to be a leak there (sprayed belt conditioner all around the seal, which is "highly flammable", and no change in RPMs...) Could a bad DISA give me these symptoms? Thanks again for all the help, just want my car to run normal for once and get rid of this P1192 code!!!

In case you didn't find this already...it's on the back driver side of intake manifold...remove cabin air filter...if you need more room, remove panel that the cabin air filter screws into too...just two screws in either 'corner' of it.
