What is this engine part? (Getting to know my M54 engine bay)

Over time, I've come to know (by necessity) almost every large item in the M54 engine bay ... but some items still are unknown to me ...

What is this engine part?

Fuel tank breather valve, aka EVAP purge valve ...

From this thread today:
- E39 (1997 - 2003) > EVAP Purge Valve Flow

Adding JimLev's information to the diagram in this post #17 of:
- Might we be able to list, with pics (realoem diagrams ok) of ALL E39 vacuum lines?


Note: I'm having trouble finding an E39 charcoal canister photo, in situ.

Do you have one handy?

Thanks to added value by Bomb5 today in this thread:
- M54 vacuum tubing ... what diameter ... what brand ... what material ... what length?

... we, for the first time (that I know of), have an in-situ picture of the three M54 engine vacuum endcaps that are listed in the parts list but (frustratingly) are not shown in the diagrams!

Quote:

  • This diagram loosely intimates there is one capped vacuum port:
  • This diagram outright says there are three capped vacuum ports:
    • Engine => Intake manifold => Intake manifold system
    • #15, Cap, D=3,5MM, Qty=2, 11611437560, $3.39 (between 1/8" & 9/64" ID)
      • One of these is probably for the CCV valve vacuum port on the M54
      • The other 'may' be if the M54 does not have an air pump, then it would cap off that vacuum port in the back of the engine where #7 hose would go in the "Air pump F Vacuum Control" diagram.
    • #17, Cap, D=7,0MM, Qty=1, 11611727176, $3.39 (between 17/64" & 19/32")
      • This clearly is the rear vacuum port behind the sucking jet pump on my M54

EDIT: Steve530 added additional pictures showing the SAP electrical valve taking one of the hoses that appear to be capped above:

I wonder what the air filter looks like? Rather dusty where that vehicle is operated.

Here is a picture of the old engine-air filter and the new filter side by side.

The old one looked OK but I replaced it anyway.

It won't rain here for the next 10 months and I take the bimmer for a drive over the mountains at least once a week, so, there is a lot of dust in the mountain roads.

Do you guys actually "wash" the engine? I've never done that as I'm too afraid I'll wash the oil out of things that need grease and electrical components that aren't supposed to get soaked.

I wipe mine down with a damp cloth, that is about it. I don't do that often either. I've never been one to detail an engine, I just don't have the time or energy to devote to it.

I clean mine two to three times a year, I've done it on all my cars and my wife's as well. I use a generous amount of Simple Green from a pump spray bottle, a soft paint brush for stubborn spots and a stiffer brush for really stubborn spots (like around the power steering cap and bracket) and a gentle spray from a hose to wash the grime/dirt/grease away, top and bottom. I will dry what I can with a towel or rag then drive the car until the engine bay warms up enough to dry the remaining water. Sometimes I will "condition" the plastic and rubbery parts with a protectant like Armorall. Be sure to cover your power steering reservoir cap with a plastic bag to prevent water from entering thru the small weep hole before spraying anything! You may need a few paper towels to soak up the water that will accumulate in the wells on top of the struts, too.

Armor All contains silicon. Silicon is deathly to the O2 sensors. Not worth using that stuff and having to worry about it being sucked in somewhere into the airstream going into the engine.

Good advice, I'm sure. Silicone is a double edged sword and not appropriate in every situation. My mistake for generalizing.

Following your caution, it makes sense for me to recommend the use of Meguiar's Silcone Free dressing or a similar product. Works the same on rubber, plastic and vinyl without the danger (and it won't discolor tires, intake ducts, etc. if used often, as Armor All would).

Been using it for years, how much could really be sucked in and where could it be sucked in from.

I mix up a bucket with very warm water and Dawn dish soap, Wet the engine bay down first with a light spray of water, then use a wash mitt and the Dawn mixture to suds up the engine bay, then rinse it off with a light spray, and blot it dry with a few old towels. The dawn cuts grease and oil quite well, but if you get it on the body of the car it will also remove every speck of wax. In fact, I use it for stripping wax when I'm doing a full detail on the paint. As far as water causing problems, a light spray isn't a problem, but NEVER use a pressure washer or coin-op high pressure on the engine.

And yes, you can go crazy and detail the entire engine compartment:

Wonderful work. Exactly what I aspire to. The trying part is I have to overcome the PO's years of "neglect".

Oh my! I'm never posting a picture of my (dusty) engine ever again!



PS: Is it silicone or silicon that you are worried about for the 02 sensors?
