They are an important part of your emission system. This traps moisture inside the separator, eventually clogging it. This leads to increased oil consumption and smoking. The fix is to replace the oil separator as well as the hoses going to it. Our kit includes everything you need to replace the oil separator in one package. Additionally, you may want to consider upgrading to the cold climate version of the oil separator.

This version includes extra insulation around the separator to help prevent condensation inside the separator. All kits contain the following parts, in addition to those specifically listed in the description: New Oil Separator New ventilation lines New silicone hose. The EGR system recirculates exhaust gas back to the cylinders, helping the car to meet emissions regulations. Part of your car's emission systems is the vapor canister.

Order Online or Call: If that 3 hose is the same hose in the picture, one end should be the plastic F connector and not the L connector shown. Is the diagram wrong? I looked again today, and I 'think' the realoem diagram above is wrong it shows an L-connector instead of an F-connector.

It would be nice if someone who knows can actually confirm that Over in another thread, we confirmed the realoem diagrams are wrong: - Might we be able to list, with pics realoem diagrams ok of ALL E39 vacuum lines? In the third diagram down titled "Vacuum control - Engine" shows an elbow 6 which in reality is the "F" connector on most E46's. Someone, who was apparently missing the small hose on the lower arm of the F connector, asked today WHERE the other end of the small hoses goes: - M54 vacuum hoses Does anyone know where that hose connects to?

Emissions Equipment

The answer of which I hope to leverage here The small hose connects from the F connector lower spout to a metal pipe which is secured on the wall just below the shock mounts under the driver side air filter housing. Thanks for the information about the smaller hose on the "F" connector. Mine is not actually missing, but is brittle. I plan to replace it before it breaks.

So this answers the question why the vacuum port on the CCV is capped when used on the M On the M54, the FPR is on the fuel filter. The second hose on the "F" connector supplies vacuum to the FPR. I suspect the "L" connector was changed to an "F" connector on the M The vacuum port on the CCV was capped on the M54 because it is redundant.

For others following this in the future, what Steve is referring to is the wondrously informative revelation he proposed over in this detailed thread: - Am I blowing smoke with this new CCV vacuum hose manifold port endcap theory? The vacuum hose doesn't show any connection whatsoever!

BMW capped off the CCV vacuum port In this case, they didn't modify the diagram at all so it's wrong in that hose 6 is actually endcap 15 not shown on the diagram or in the parts list BMW changed the L connector to an F connector so that the hose that previously got suction from the CCV would now get suction from the F connector Again, they didn't bother to fix the diagram; so the diagram is confusing at best and dead wrong in many ways!

These changes are partly the reason for all the confusion which is noted on other threads - but which isn't fully outlined in any! If you have the M52 engine, I'd expect to see: Your fuel pressure regulator is in the engine bay Your CCV vacuum port is connected to that fuel pressure regulator Your rubber elbow has an L connector on top Is that what you see?

I broke the smaller hose and went to Autozone but they said they do not have the same size. What size is it and where do you guys get it from? BTW, some say to just bring the hose to Autozone The better method is to find a better source. Part K, they are an on-line and catalog industrial supply house.

In the process, the lower tube that goes into the top of the rubber boot broke. I attached a picture. Does anyone know what the broken tube is called or what the part number is? It looks like the connection piece broke. Also, the diagram shows that the fuel tank breather valve is vertical, while in reality it is mounted horizontally in the front of the intake manifold. I asked for a "F" connector 13 32 7 When a crankcase breather valve begins to fail, engine drivability suffers. You may have a rough idle, hard start or a check engine light that is ON with fuel trim faults.

If your engine is consuming oil or smoking, checking the crankcase vent valve is a good place to start. The crankcase breather has also been known to emit a honking or wheezing sound from the engine when failing. It is mounted to the back of intake manifold, near the firewall. The crankcase vent hose that runs from the valve cover to the crankcase breather valve is the hose I find broken the most.

If you are doing a repair where this hose may be moved or bumped, have a spare on hand, because it will break. When replacing your crankcase breather valve, I suggest replacing all the vent hoses and the oil drain hose to dipstick tube. They become brittle over time from exposure to engine oil and heat. When removing, the parts are likely to fall apart in your hands.

Have the parts shown below before you begin in order to avoid vehicle down time. Early M54 6-cylinder engines utilize an external crankcase breather. This tech article shows how to replace them. On late 6-cylinder models, the crankcase breather valve is integrated into the valve cover or external. This will be covered in a separate article.

Squeeze the collar and pull it straight off red arrow.In which I solve the case of the missing engine oil, and dig deeper into the belly of the beast than ever before.

The following error codes were all encountered prior to resolving the issues detailed within. These engines, I reasoned, were bulletproof. Meanwhile, the check engine light had become a constant in my life. I recall that the check engine light had been intermittent back then, and it held off just long enough for me to pass inspection. I did this while waiting to have my vehicle inspected.

I drove the car following the inspection, only to find myself faced with the check engine light once again. It was time to get my hands dirty once moreā€¦. I pulled the spark plugs, starting from the front of the car. Observed that the top, where coil sits, was covered in fine carbon buildup, kind of like soot. Exhibited corona wear. Threads were fouled up as well. Pulled the DISA valve and found the flap loose.

Fortunately, the vacuum pot was still functioning. On this inspection, I observed that the end of the rod had shorn off, leaving the flap inoperable. I also saw a pretty cool project that involved replacing the M54 valve cover with an M56 valve cover. My original plan was to pull the old CCV and replace it along with the various hoses.

I ultimately pulled the intake manifold. For reference, the measurements above indicate the inner diameter of the hose, followed by the wall thickness in millimeters. ID x t wall. I decided to redo the vacuum hoses with silicone. While searching, I turned up a Contitech part that fit the bill perfectly. The 7mm vacuum cap on my intake manifold was also in need of replacement. The original piece had a break near the lip, and two hairline cracks running partway down the length of the cap.

Someone had suggested that using a zip tie on a failed vacuum cap around its base would help, so I installed the new vacuum cap with a zip tie for reinforcement. I should have checked this before placing the order. Prior to removing the intake manifold, I trashed the insulation Armaflex? I ultimately stripped the cold climate CCV of its insulation entirely. It probably works out okay, given the low cost of the cold climate version kit when compared to buying individual parts, but the whole mess could have been avoided with more care.

My magnetic pickup tool came in handy on more than one occasion.

If you don't understand it, it's not my problem". Could also be fuel tank breather hose, secondary air pump hoses or the suction jet attached to the brake booster.

What's the last 7digits of your VIN? Post pictures of where all the loose ends are connected. The vacuum lines on the M54 are very simple compared to most other engines. There are three vacuum ports on the rear of the intake manifold. Two a small and a medium are capped off.

The third small, 1. The secondary air valve mounted on the head, just above the exhaust manifold is the only control system. Most of the length is a rigid tube surprisingly expensive -- avoid breaking. The tube and components are connected by short lengths mm of flexible tubing. The two vacuum draw lines are for the Evap system and the brake booster. The evap system has a solenoid valve mounted on a bracket behind the alternator, close to the electrical distribution box. A short hidden hose goes from behind the valve to the intake manifold.

A hose with a quick disconnect goes from the body to the valve. The brake booster vacuum line is slightly more complex. Unlike many engines, it has a "jet pump" to provide high vacuum even with continuous open-throttle engine operation.

Thus it has an extra vacuum hose to the 'F' fitting on the intake boot. The venturi jet pump itself is mounted on a clip aside the throttle assembly.

The main vacuum tubes all have band crimps. You should never need to break these. If you have to work on the intake, disconnect the fitting at brake booster.Recover Lost Password.
