Hey fellas, Recently removed intake manifold in order to replace a whole bunch of fun stuff. Under close inspection I noticed that I'm missing a part. I've searched high and low across forums, youtube, etc. but haven't found much useful information beyond superficial. I messaged BMW directly...

Hi everyone, I had 2882,2883 codes fuel trim adaptations problems with my 2004 325ci couple weeks ago. I did check everything and found some vacuum leaks under and behind the intake manifold and also fuel pump needs to be replace. Im replacing all the vacuum lines, fuel pump, fuel filter etc...

I discovered a couple days ago that both of the coolant hoses that fit beneath the intake manifold are leaking. Well, one of them is, but I'm replacing both just 'cause. Is there anything else that I should replace while I have the intake manifold off? (vacuum lines, for example) I don't want...

Hi fellow bmw enthusiatst! Im having a odd problem with my modified m52tub28. To have a idea of my setup: K&n inlayfilter 330i filterhousing/maf, intake manifold/camshaft. Ebay headers, m3 exhaust system (post cat o2 delete), m3 6spd gearbox, 3.38 diff, 19” m3 rims, bilstein b12 prokit...

e46 m52tub engine. The previous owner for unknown reasons decided to drill a hole in the intake manifold, stick a vaccuum hose in it, connect that hose to the fuel pressure regulator and plug the vaccuum hose that goes to the ccv with a rivet. Does anyone know why would you that? And what would...

Hi all, I bought an e46 BMW 330ci model 2001 one week before and there was an excessive leakage of coolant from the heater inlet pipe which was in worst condition you can see in the pictures. I went to mechanic yesterday to change this with new one which I already purchased so they removed...

Hello everyone. I'm getting ready to reinstall the intake manifold on the 2001 330ci coupe, manual transmission. I know which hoses go to #1, #2 and #3. But the two locations denoted by the arrows. I don't recall anything being connected to them, whatever they are. I'm under the impression...

I was taking off the intake manifold and after removing the it from the engine, these two small plastic pieces fell off of somewhere from the manifold on to the starter. The pieces say R L on them. I've looked through the diagrams but couldn't find them. Please help. 2004 325ci - M54

Hey guys! Already done some searching on this and couldn't really find anything, plus I'm not sure exactly what to search for. I have had a vacuum leak for a few months and have slowly been replacing things trying to fix it. It has gotten better but is still there. What I have replaced so...

Hey guys, would it be worth it to remove my intake manifold during the winter? I have a coolant leak right under it, and Im pretty certain its coming from the heater hoses. I already have the o rings for the hoses, but I still need to order the manifold gasket. How many hours approx. did it take...

Hi, Recently the heater inlet pipe busted on my e46 325i 2001. Unfortunately the only way to reach there was by removing intake manifold. Now I see that intake manifold has all those carbon soot and oil spill (dried) all the way. I used a light to see that and actually when i touched a paper...

After I got my front tires replaced today, I came back home and saw my neighbor working on his 2004 BMW 325i. I went to ask if he needs help. To my surprise, I saw a really weird engine in the engine bay. He has 2004 e46 325i with N46 engine on it or something similar but everything else in the...

Okay everyone I want to start off by saying this is my first post/thread here.. so be gentle. I'm not stupid, but I am rookie, so please excuse my ignorance. I've had my 01' 330Ci for about 4 years and ever since I can remember I've had a problem with my idle and SES light mainly during the...

Starting this past Friday, my 2001 330i starting giving me issues. While driving, the engine would all of a sudden take a dump. RPMs would drop down, and the pedal would be unresponsive. I would have to completely let off the pedal, then slowing press the pedal to regain control and drive...
