I took this pic 5 minutes ago
fast aproaching 111k miles - Seattle (aka rainy weather)
Mine used to look like that - I changed the AOS

 

Michael - that looks excessive. When I would take short trips during the winter here, I would get a little bit of the milkiness in the filler tube, but maybe a fraction of what you have there. What oil are you running?

 

Hello Whitey

Oil is Mobil 1 0-30?

Can't recall if the 30 weight number is correct but it starts with 0.

Oil was put in by the main dealer 10,000 k ago

 

Is this oily thing the AOS?

 

no - but that doesnt look good....your car has 3.6? I dont see that on mine...

here is a picture... the first is looking from the rear...what you see near the filler cap... the second (with red circle) is the AOS - also know as PITA to remove as you can see its against the rear seat area and there are a few things in the way.. I dont think I can even see mine, and I know where it is

 

That is a pressure relief valve for the crankcase. Connects to AOS and vents to atmosphere if necessary. All the engines have one.

 

since it is dirty - would you guess the AOS is making it do more than it should be doing? or is something wrong there - I dont see that part on PET...

(PS lotta red dirt in AU ?)

 

Part number 996 107 047 51

 

so that thing just looks like a piece of pipe... if it is leaking I would bet either the hose is not installed tightly, the o'ring is bad on the connection or maybe the part or the tube (hose) has a crack... still I dont think that is the cause of the cream........

 

Ivangene "I owned 4 bugs, 69', 77', 60', and a 73'
they are all air cooled, they dont have OIL??"

Did you have many engine siezures? No water maybe, that was my point they made "milk" with just condensation. That said the OPs oil filler looks way too wet.

 

So there may be an o'ring or a loose hose causing the leak in my 'photo. Good to know what that is -- and i I was wondering whar all the fuss was about re getting to is if that was the AOS.

Ivan's pic answer the question for me -- thanks.

I have just done a "suck on the hand test" at the oil filler tube -- results:

Enging cold or hot same results,
at idle take the cap of -- enging immediatly starts to hesitate and run rough but after 30 sec's has not stalled,
put the cap back on, within 5 secondes -- idle is normal,
pull the cap off, place palm of hand over the filler tube opening, firm tug, more than noticiable and less than firm, not enough to make a suck noise no matter how fast the hand is drawn away, same "weight sensation" on the had as say an upturned opem palm holding a baseball.

So, does the "seat of the pant's test" = my AOS is working?

 

While it's difficult to e-diagnose - from your description I'd say AOS is ok.

You burned of excess moisture from your oil, as per earlier discussion.

Dropping oil would confirm that it's clear of any water contamination - just a suggestion.

 

Yes - it seems like good advice to drop and look at the oil - will do that through the week - will post back with the results.

Will have to get a filter so it will be Wednesday before I can do that.

What will be interesting is to from then on log my travels and the ambients and the humidity - should be able to do that - and see when the droplets of moisture appear on the filler cap with the fresh Mobil 1 -- ie -- to see if it is moisture froced out of hot oil or ambient condensation (does that make sense?)

 

HAHAHA - you did read that right, I was joking

(seems some of the air cooled guys think us water pumpers aren't very engine savvy )
Good catch

to the OP - I would say its working, but its like giving a haircut over the telephone.....
that said, I thought mine was working too, I changed it for a completely differant reason, and did not solve that problem BUT did stop getting the cream - though I wasnt worried about it - like I said I was chasing another problem.

Also why it would be nice to "invent" a homemade test set up to put a solid number on a line and know for sure (the 5-12" thing)

 

My car is a 2002 3.6

Is there a way to use some other type of tester for the task? of measuning the vacuum?

Also, the oil filler hose and cap is a dead end -- like a backwater that would not get any reall circulation of crankcase gasses -- is there a way to have some airflow introduced -- perhaps from another point in the AOS system to get the air moving in there so that the buildup is "dealt with". Seems like an unanticipated design "issue".
