[diesel_mercedes] Progress

 

Haven't been writing much lately. Working on my dad's estate and trying
to keep the 240 in running shape. Driving it 50 miles a day seems to
have cleaned the engine up to a point. A few weeks ago, I made the
mistake of overdosing it on diesel cleaner. I suffered through a tankful
of horrible idles. Word to the wise: there is really such a thing as too
much of a good thing.
I still am having trouble getting it to start after short runs. But I
think I am on to something. Tonight, after cranking it to near death, I
just for the heck of it decided to disconnect the vacuum line going to
the kill diaphragm. A hiss of air showed that it was still in kill mode.
Replacing it, I jumped in the car and it still would not start. This
time I left it off and it fired perfectly!
So, my problem is that the ignition vacuum valve works to kill the
engine just fine, but it does not release the vacuum once the key is on.
Here's the question:
Turning the key counter clockwise, the valve opens a path for vacuum to
pull the vacuum valve, killing the engine, but once the key is on, how
does it release said vacuum? Is it possible that the lines can be
reversed at the valve, and one of the ports opens to the atmosphere to
release the vacuum and the other does not? And being reversed, would it
also cause a vacuum leak?
I am going to reverse those hoses in the morning and will report back.
If this is true, I will for the first time have a truly reliable car.
On another front, I bought a transmission mount from Rock Auto a while
ago and finally got around to installing it. I should have thrown it
away instead of the old one. The center attachment, which I now realize
serves only as a safety, is cast into the rubber on the new one so
thoroughly and stiffly that when installed, it feels as if the engine is
sitting straight down on the cross member. The car drummed and vibrated
like a tractor. I couldn't turn the radio up high enough to drown out
the noise! I luckily was able to fish my original out of the trash (I
now realize that there is nothing wrong with it: the center is SUPPOSED
to be loose!) and reinstall it. I figured out that it might have settled
a little and the center was transferring some vibrations, but now that I
see how it is designed, I left the through-bolt loose (it passes through
a pair of slots in the cross member intended to make for this type of
adjustment) until the last, with the weight of the trans back on the
mount. I then tightened the cross bolt, making sure that it was centered
in the area it passes through. The car is smoother than ever.

[diesel_mercedes] Fuel Economy & Near Disaster '84 300TD

 

So ;

Many people ask me _why_ the glove box full of little spare parts and the ash tray full of spare fuses, "Just So" hose clamps and so on ? .

I stopped in to fill the tank of my greymarket '84 300TD and looked at the clear plastic fuel intake screen, it's got a blue screen and has been there some time now as it's always clear .

I noticed some tiny bits of crud and turned it a bit to look at the underside and SNAP ! the inlet barb broke right off in my hand .

I looked in the glove box and discovered NO spare filters .

I opened the tool kit and grabbed the original screwdriver, removed the broken off screen and short bit of hose on the intake side, re connected the IP's intake hose directly  to the steel pipe from the fuel tank and we were off again  .

I also noticed the short bit of hose wasn't the typ  I like although it looks flexible and fine, the two clamps on that side were also Ideal "jubilee clip" screw typ hose clamps, I hate those and so will soon replace them with proper # 14 (?) band typ hose clamps, I'm sure I have spares in my Coupe's ash tray .

Anyway, 319 miles, only 20.3MPG ~ is this normal for a TD ? .

I wonder because :

A. it's heavier than a Coupe or Sedan

B. European Specification so maybe different fuel economy (?) .

Anyway, it's full o the brim with bio based (not veggie) Diesel fuel and SWMBO can drive it until I get the new intake screen and hose clamps etc. , etc. .

[diesel_mercedes] '85 California Emissions

 

I can dig it Rob ;

I changed the manifolds on my '82 240D because one 6MM threaded hole was stripped and every time I lifted the hood it accused me of not caring .

Some times one really should pick their battles more carefully .

Nate,

I thought about changing manifolds, and have some from Brian's earlier dead engine, yet there are other routing issues with the A/C etc, which all are CA '85 specific, and would have to be changed too. Not impossible, yet more than just manifolds.

[diesel_mercedes] Wiper Relay W123 & Leaky Oil Pres. Gauge

 

Thanx Rob,

That's a far better picture .

As far as the oil leak, if your oil pressure gauge had a jittery needle, it's almost certain the gauge is kaput .

If it was rock steady even at hot idle the 10MM ferrule nut on the back of the gauge _might_ be loose, it only takes a 1/16 turn to begin dribbling oil , guess how I know this ? .

I'd use a junkyard gauge, when you're removing it look for a tiny little thingie (Technical Term there) in either the gauge's port or the open end of the tube, it's a device to stop the gauge's needle from jittering and causing the gauge to fail .

I can provide both the part's proper German name and part # if necessary but most older Diesels have had this part installed decades ago so take a look for it .

Whilst you have the binnacle out and apart, get some Meguiar's Plastic _Polish_ (NOT 'Cleaner) and use it and some basic cheapo Scotts toilet tissue or lens tissues (in case you're suddenly rich) to clean both the inside and outside of the binnacle's lens ~ doesn't take long and really helps make the illumination at night .

Me, I ever so carefully hand wash the entire binnacle including the light guides.....


I hope this helps .

Hi Nate,

I was there earlier in the year:

Jan 8
I just replaced the W123 Windshield Wiper Relay, which is up behind the
gauge assembly, and just so you know, it can be replaced w/o removing
the gauges. I needed to do this because the intermittent function
stopped working on the wipers, and we seem to have rain this year.

Here's a forum post showing which relay is what, though the wiper relay
is way up top, against the dash:

http://www.benzworld.org/forums/w123-e-ce-d-cd-td/1269494-where-wiper-relay-located.html

While I was doing this, I noticed a bunch of black motor oil coming from
behind the gauges. What is that from, the oil gauge? easy fix? I have a
second set of gauges mounted on the steering wheel shaft cover, so it's
not easy to remove the gauge assembly, and get the parts I need before
opening it up further.

Thanks

[diesel_mercedes] Intermittant Wiper Relay W123 ?

 

THANK YOU BILL ! .

The third result there is it : http://www.pelicanparts.com/techarticles/Mercedes-W123/80-ELEC-Intermittent_Wiper_Relay_Replacement/80-ELEC-Intermittent_Wiper_Relay_Replacement.htm#Customer_Comments_Bookmark

And here's the money shot, please to note the relay with the red arrow IS NOT the wiper relay, if you open this photo on your computer you'll see the wiper relay just behind and to the right, plugged into a female receptacle .

Now I can begin dreaming about taking my dash apart, I've been wanting to order a new plastic binnacle since last year when I built one up out of all the various best W123 binnacle parts I had plus a rebuilt speedo .

My binnacle is worn and cracked where the clean lens is glued to the black plastic ~ I cleaned it like mad and carefully hand polished the occluded lens inside and out but it bothers me knowing it's broken and someone always seems to take or destroy the W123 binnacles before I get there .

Relay Part #: 000-821-08-63-MBZ

FWIW, I have never owned a 1977 240D ~ our first Mercedes Diesel was and remains our 1982 240D .

This job is on my ancient and battered if beloved 1984  Diesel Sports Coupe .

I _did_ have a first year (? 1978 ?) NA 300CD a while back .

[diesel_mercedes] Honda CT90

 

Thanx Max ~

To whet my whistle maybe you could take a photo of it and send me to remind me......

I'm also actively looking for a non seized up older VW engine, a 6 volt one (109 flywheel teeth)  to patch up or make run for my 1959 Beetle project .

I have a very few dollars I can spend .

I'd think it a fairly simple thing to replace the '85 Ca. only manifolds etc., the $avings in air filters alone should cover the Junk Yard parts in a few years.....

Once in a while I see non - egr manifolds, they're (IMO) the best way to go .

The bad bit about the possible air cleaner mounts failing on my Coupe  (I've still not looked yet) is : they're OEM from the M-B Classic Center, only a year or two old and the last ones I bought from them are _NOT_ original parts ! (no casted in Mercedes logos/part #'s) ~ they're the same cheapo 'URO' brand crap I can buy anywhere for $1.50 each ~ I wrote and asked Tom what's the deal and we said " that's it now" ~ I find it hard to believe Mercedes would substitute chinese carp parts in their sealed bags but VW did it to me in the 1990's so we'll see .

If the mounts are parted I will be taking them back for warranty replacement .

BTW : I am loving my re-calibrated hearing aids ! .

Nate,

I know how you feel. I got a tin can rattling around under the hood, well actually it's the thin outer cover over the hollowed out CAT. Still thinking about the best plan to stop the rattling, maybe a few small holes and wire the parts together. It's a PITA to get in that area, so I haven't done anything with it. When I get a moment...

I got new molds for my hearing aids and a hearing test that indicated they needed adjusting, all fine and dandy until I get out to the car, light it off and hear some high frequency rattling......

I need to see if I can do an oil change anyways so will look under the hood soon and see if it's the air cleaner mounts again .
