Hi, just took the engine apart, cleaned, painted and put back together, now trying to identify all parts and connections and am stuck on the below. Are there any people with the same engine that can assist?

There are 2 thin rubber hoses coming from underneath the intake manifold, I think they would usually both connect to the vacuum for the exhaust flap, is this correct and if so can I just block them off?

And What is this part and where does the tube shown connect to?



Thank you

that bit looks like conduit for a cable,dunno about the vac hoses,just see if you have and spare things to plug them onto

As soon as I read your reply above my question seemed stupid, so I thought I'd have another look to see whether it had any references on, and it did which from a search on google states it's a fuel tank breather valve! So this might help me find out some more stuff about that part, will keep searching for ideas about the hoses from the bottom of the intake manifold

Hi there, I one put one of these engines into my E30 - you'll be fine blocking the breathers on the inlet I did this in the E30 and it ran fine!

That looks like a tube to go to the carbon canister (which absorbs fumes from the tank and releases them into the manifold when conditions allow).

So I guess that on a kit car it's not essential and is another part I can remove and plug up the hose leading to the intake manifold?

Its not the vacuum hose for the brake servo is it? On my M52 engine it comes out of the side of the inlet manifold and all that I did was block it off with a short piece of hose with a bolt clamped into it. You can just see it to the left of the top if the dip stick in this photo. The other bits of pipe that are around the same area connect to the idle bypass valve, the cooling water for the throttle body (2 pipes) and, as already mentioned, the fuel tank evaporative emissions control carbon canister.


Description

Thanks for the reply, it's not for the brake servo although I do need to block that off to! It might be for the carbon canister, I might just get the engine started ASAP and see how it runs without it as from what I've found so far if I don't have the bmw tank etc then this part isn't essential and it will only throw up a code if the pipe that goes to the bottom of this part is disconnected.....I think

Even if it does throw up a code, my understanding is that the ECU will just log it to be looked at during the next service rather than going into a limp home mode that would effect your enjoyment of the engine.

I don't have it either and my engine works fine.

Perfect thank you, that's exactly what I needed, it will be a couple of months before I start it but i will remove the part and block any pipes for it at the mo, thank you
