OOoh I'll just get there later
Meet at the cuban rest

I'd like to meet everyone
but seems like I may be seeing Enrique too much

The shadow is not toohappy right now
with her wur rear port hosehanging on ny a spider web
& this green yellwo thing I have been blowing in til I;m red in the face

Jim B. · #**1007** 10-26-2007, 11:09 PM

Thanks for the advice on the ashtray. I think I understand better now.

All right, I will start a flurry of PMs around to everyone and ask if 10:00 on Saturday 11/03 works for everyone. I am OK with that and so is Paul S.

I will have to get ahold of Curtis, which I think I can do, see if he would like to come..

Likewise, Ernesto, and the others will need to know. I will PM the rest of you.

Shadow I hope, knows about this she should be all right for 10:00, because she checks in here frequently and OWNS this thread anyway.

Shadow says, there is ALSO a parking lot behind the shop sufficient to hold several more cars, at an upholstery shop or something adjoining Enrique's shop.

MR MB is supposed to be easy to get to, Charlie, so there would be no problem. It is right off the highway or something.

We can go some place for lunch maybe after. Ernesto knows a great Cuban place right across the street from MR MB, nearby, and promised me a lunch there anyhow. I trust him, as he was born in Cuba and knows what he is talking about.

Maybe I should get a detailer to see if he can take a swipe at my car too, like you are going to.

If we get this thing going, I wonder if we ought to ask them over in Diesel discussion, about this gtg. Their policy is they might "sticky" it if there is a SPECIFIC time and place. We are close to that now. He just doesn't want endless arguing about time and place on a sticky when it has not been decided. If we go for a sticky, we would have a MUCH bigger turnout.

I would like to have Buzz, the airline pilot from Ontario, come out, for instance. He has made it to the Nor Cal drives, you would like him, he has a black 190D and a '91 350 SDL, I got a ride in it , it is gorgeous. It would be an EZ drive for him to MR MB if he is not busy.

Hope to see you there!!! Thanks so much for your help.

It drops the airflow capacity. So backwards it would be working with less to start with and , of course, not expand after passing the orifice. Installed the other way, there is more flow to the orifice, then less...So in effect it will work either way, now if there is a one way flapper in there, then it won't hold the vacuum installed backwards. I don't know if it is intended to hold vacuum or not, or to just provide an orifice.

Well I did it. I bought a set of Beru ignition wires from Fastlane. They were just about $65.00 more than Bosch and I figure that I won't have to change them again for years.
They sould be here before the GTG at Enrique's on the 3rd.

Do you know which way air flows into or from a port in the front of the intake manifold?

If air goes in then the the orifice flow should be toward the intake
If the air flows out of the intake port then I guess the orifice should be pointing away???

Gosh darn this thing is bugging the heck out of me

I just want to help that poor car
got to watch out for it...

CamelotShadow · #**1009** 10-26-2007, 11:20 PM

They sell wood glue
Elhmers makes it

I;d try that

it cleans up easy
if you get something to hold it it make a good hold

Heck I replaced some ivory keys on my piano
had to get new ivory fit it
sand it til it was flush
sand the keys
then used plain elmers & secured with rubber bands

Did a good job

Get a tube of Wood Glue
Get the dark color it blend better on dark wood
It won't hurt the wood

CamelotShadow · #**1010** 10-26-2007, 11:26 PM

I think the orifice
goodness
this thread has turned

seems to hold the air & slowly let it out
It seems to fill & then you can't blow as well into it

To me its seems to be working both ways

hard to tell as you fill it with air
& then it seems to not work

Help

Where is Mr Brisbane

Will the car idle lumpier\with the air assembly off?

I really don't want to put this thing on the other way
then hook up the air assembly to see if it runs any better the other way

Update Enrique was right

CS,

An orifice will allow air BOTH ways, only one way will be less volume.
Vacuum is suction that is generated inside the manifold. Therefore, the flow direction is into the manifold.

Is there air flow though the valve from either end?? Both ends? how much and which end?

Worst case scenario.
Plug it back in opposite the way you took it out(see your picture) and see if it makes a difference in how the car idles or runs, then switch it back the other way and do the test again. You should be able to tell a difference.....if not re-install it like it was and know Enrique was right.

Whoops looks like i should have posted up a diagram so your mechanic can set your vacuum hoses correctly.
It's 30+ C here,it's hot and I ve just returned from a road test in this 500SEC AMG. I'm not real happy yet,it's no longer sluggish but it's no fire breather either ( I guess i'm used to the M-100 cars I normally service).At 130mph it's very smooth and still has plenty of urge but it was changing up too soon,I found it also had an aftermarket kickdown relay which let it change up too soon.Various vacuum connections were replaced this morning so it's getting close to it's supposed 276 Hp.

Give me a few minutes and ill post a vacuum diagram for the earlier Euro 500SEC .

I hope he was right
He checked it
Brissy is goingon color
& who knows is thats a accurate way to install one
Still the darn things should have an arrow

Its hard to get air in
Hard to tell

The car had this disconnected
from the intake
it was the way I reinstalled & Enrique verified
MAybe its not working well?

So the car would be pulling in alot of air without thhis valve in place
but then again the intake would not be effective on the loop of WUR throttle & Distrv vac...

I literally was out of breath down there
blowing in this darn thing
Air sucks as it is
& right now I;m just aggitated by that WUR vac hose

I'm sorry but I might have to check the work next time
not that much could have been done at 5pm

Still I trust he;ll make it right
just hate to have to have his guys take off the air assembly & clear that WUR area of wires to get that hose on right

I know it happens
Guess its nothing in the scheme of things

Thanks

I wish the MB dealer was open
I would take this thing to them
maybe get a new one
but I really don't want to wait til Monday to deal w this
& haave the car disabled
but guess it ran without it before
it would survive again...

Update Enrique was right...except his guys did miss the wur rear hose thats almost off...

mercmad6.3 · #**1014** 10-27-2007, 12:12 AM

OK ,so here is a picture of the vacuum as it relates to Shadows' euro 500SEC.
As her car is similar to one I am tuning for a customer i have had to do a a lot research to find the facts regarding the actual set up for this model.

The Orifice ( 9) is a specific item ,and must not be confused with similar devices on later 500's.
In the picture you can see it says it is white(WS+ weis) grey in the center marked Gr and Green (Gn=Gruen)
It also only works in ONE direction only.

I made a copy of your diagram as well as my setup
I even notated the new hoses & old & made mention to tighten the rear WUR hose
I left it there with the car
but don't think they looked at it...

My guy is a good mechanic
but his guys sometimes
have there own ideas...

So what do I do with blowing in this bloody thing???
How can I tell if its working?

Its driving me crazy

Hey thanks for sharing your research with me
Everything helps.

I checked the WUR
it does end in 101
Sorry I was in no mood to document the wntire 3 this evening

I'll have to look your new diagr over but most of it looks the same

Still I don't know how to check that orifice & does it flow to the intake?
I would think the wur is hooked to that rear wur hose
so does air feed to the inntake in the back by the fuel dis
or does it feed to the WUR from the intake?

I thought if I understood the way it works I could figure this darn orifce batter

Mine is yellow now
could it have been weis when new?
It says pierberg I think
w germany
there is a grey center portion

WOW you got it!!!!

I have the valve
I'll take a better pic

Anyway
thats the bugger!!!

Thanks
really???

well you know
no one is perfect
& the Euro is a bugger

CamelotShadow · #**1017** 10-27-2007, 12:33 AM

I can't read the colors in the 9 orifice
looks like it might be weis toward the intake
thats the way mine was

So maybe it was right

ooppps

Ooh I feel a tad britneyish
but least I don't crash into merc while parking & walk away...

mercmad6.3 · #**1018** 10-27-2007, 12:37 AM

No need to worry about a pic,Peirberg made all the vacuum goodies for the German car makers.
Just pull it off ( it's a slip fit on the rubber hoses ) and turn it around.
With it reversed you won't be getting a proper aceleration .Even though these cars move off in second they are still reasonbly quick but if the fuel isn't being delivered properly it will be down on power.

Its off
its in my hand
your diagram appears to have the white side going to the intake
It was white you can see it where the hose wasprotecting it
So its yellowed with age

Thats the way mine was

Looks like your care may be switched

Doesn't the diagram have 9 ws toward the intake & gn away?
so mine should be right

I don't understand
Logic is a good thing
but its hard to argue w a diagram

CamelotShadow · #**1020** 10-27-2007, 12:49 AM

Thanks for the diagram
Interesting

Looks like the wur is more than a WUR
seems to be sort of a idle control regulator

Seems the orifice comes into play under acceleration
