Vacuum pipe question

Post by shadyracer01 »

Hi All, Im after some guidance on which vacuum pipe goes where really. Got through most of my issues getting my 323i running again but need clarification with both vac pipes from distributor and the vac pipe from T piece in engine breather hoses.
All vac pipes are black in colour, can anyone help by telling me exactly which ports on inlet manifold to connect to please?, at distributor theres an outer and inner port on vac diaphragm casing, (inner being closest to engine block).
Its a Uk spec 1982 323i k-jet with manual box and no emissions add ons.
I also just want to say how invaluable this forum has been for me, thanks to the info and advice all you guys have shared on here, its only now Im having to ask for help, most of my other issues resolved by reading, understanding and having available spares.
However, I couldnt quite find the answer to my question so here I be. :)

So I had a similar issue, I dismantled the engine to have it rebuilt and didn't note down the locations very well, which I regretted big time.. I then downloaded loads of images of 323i engine bays from all angles and then found a local owner who has a rusting 323 baur parked in the drive, I asked he allowed me to spend a few hours to take pics, and note exact positions of all pipes on engine. That's how I managed to sort the problem, maybe you have a local owner or attend a owners meeting, and take details from their engines.. I hope you manage to resolve the problem!

Thanks for your reply Vic, I did same as you and whats worse is I have 2 323's but have lost any pics i took for reference and have probably borrowed a bit of hose to repair something else in the 10-14 years ive owned them..Doh!
I dont know of any 323s in my area,(east Scotland) but hopefully I'll figure it out with a bit more research :stupidme
