Re: [MBZ] Miserable jobs (and crappy diesel idle)

I know what you mean - electronic crap is what caused me to sell a perfect 
'99 Camry with 99K mi and buy our '91 300D with 99K mi.  The Camry looked 
like a sea of little black boxes  while it was perfect at the time 
eventually problems would occur.  I quickly realized I would never be able 
to troubleshoot problems like I normally can.


Even back in '91 the electronic stuff on a diesel was really getting bad - 
but nothing like a gas car!  Electronics have revolutionized the modern 
engine but without the proper (and often expensive) gear to check things out 
it makes troubleshooting very hard.   Especially for things that occur at 
speed.  Oh well, it's progress I guess.

Rack damper bolt looks old, but is gold through the oxidation I think.
 I'm going to replace it anyway, as adjusting it isn't very effective.
 After more tinkering today, its slight better.  But still not good.

Primer pump is new.  I'm going to investigate possible air leaks in
the fuel supply... the rubber hoses are all new, but there are some
other hoses and fittings around the injection pump to consider.

I checked timing chain stretch... its almost none, perhaps 1 degree.
The tensioner, on the other hand, didn't seem very stiff to me.  I'm
going to compare to my 300SD and consider this a possible issue.

Thanks for the tips guys,
Jaime

Hi everyone,

Allow me to share:

So, yesterday, I got to leave work a bit early.  Since the weather was
really nice, I thought I'd drive my 82 300D home instead of the usual
company test car.  I'd have a bit of time to explore why the fuel  gauge 
is

unreliable.

A little background:  I bought this car two years ago because it  would 
be

the perfect guilt free daily driver I could leave sitting at work  for
weeks at a time and not feel bad.  Just a bit of rust, but a one owner
garaged car with 140k miles.  Trans flared, and it needed a bit of 
sorting

out.  The idle was crappy and it had no power.  So, it make this email
shorter, I'll summarize:  I cleaned up the lines the alda, replaced  the
injectors, and installed a manual trans from a 240D (and loads of  other
little repairs).  Suddenly I had a car that I've always wanted.  The 
engine
runs great, has loads of power, doesn't consume oil.  Its like my  old 
240D

on steroids.

So, fast forward to yesterday.  The car has been sitting for a  while... 
I'd
drive it home every few weeks in nice weather,  I racked up a  whopping 
2500
miles in 2009.  And about 400 miles this year so far. (Including a  trip 
to
the shore last weekend, about 150 miles).  I should mention the car  sits 
in
a heated and air conditioned warehouse when its parked... possibly  the 
best
conditions you could imagine for car storage.  (Thanks to the 
unfortunate

closing of Becker of North America)

I throughly enjoy the drive home... the car runs excellent.   Especially
memorable was the on-ramp to the Garden State Parkway, winding out 
second,

shifting into third, and drifting sideways for the last few yards as I
blast onto the highway at a crazy 50mph.  Wow, I remember how much  fun 
a 4

speed W123 is!

But, that uneven messy loud idle is still there... just like it was  two
years ago.

So after the hard run home, I set into work.  I had ordered up a new 
seal
for the tank sender a few weeks ago to be ready.  I removed the  sender, 
took
it apart, and found it full of goo and crud.  Yuck!  I cleaned it  all 
up, re
soldered the reserve wire, and reinstalled.  All is well.  But the  crud 
got
me thinking... if all that stuff is also in the tank, it might  explain 
the

crappy idle.  Perhaps there is alge, plugged filters, etc.  I  remembered
back about a year ago when the car stalled out on me after taking a
(another) fast on ramp with only a bit of fuel in the tank.  I  decided I
needed to replace the tank screen.

So this morning, with rain in the forecast, but the sun in the sky,  I 
went
to work.  In the basement, in my collection of parts I never used, I 
found a
new tank screen and the fuel hose that attaches to it.  And some  nice 
german
hose clamps.  I ran to the home-disappointment, picked up a yellow 5 
gallon

diesel can for $10.  I climbed under the car, and did the dirty deed  of
disconnecting the fuel line running from the strainer and feeding it 
into my
new diesel can.  The 5 gallon can wasn't enough, so an empty simple 
green
bottle, and my oil drain pan collected the extra two gallons.  Just 
enough

diesel ran down my arms and on the driveway to make this job  especially
miserable.  As I reached for a 19mm wrench to remove the fuel line  from 
the

strainer it started to rain.

So, the strainer came out with the hose and much to my surprise, it  was
perfectly clean.  It looked about the same as the new part I had.
Disappointed with the effectiveness of this miserable job, I  installed 
the
new strainer, clamped up the hose, and poured the 5 gallons back  into 
the
tank, along with a can of diesel purge (just because I found it on  the 
shelf

too).

So, now I need some advice on how to continue with this idle problem  I 
have.

Here are the symptoms:

-Engine starts easily cold, but surges between 500-750 rpm at about 20
second cycles until it warms up a bit.  It fires on all 5 cylinders  the
whole time.  This is worse in the winter, when the car will  sometimes 
stall.
-At warm idle, the engine fires on all 5 cylinders evenly, but is 
generally

loud and a bit naily.  Its nothing like

A worn out tensioner WILL cause surging.  Change it.  It is an easy 
DIY job on Iron OM engines.

Re: [MBZ] Miserable jobs (and crappy diesel idle)

2010-05-08 Thread Peter Frederick
Check the fuel lines in the engine compartment -- if they have not been 
replaced, tis' time to do so.  They crack and allow air into the suction side.  
Watch for a stream of tiny bubbles through the clear pre-filter.  Eventually 
leaks here will cause it to start hard.

Does it have an idle speed control (that little D-shaped thing on the dash)?  
If so, you really do need to use it when it's cold to speed the idle up.

Check for loose linkages, too, although that shouldn't affect idle too much.

The Diesel Purge will help if you have a sticky rack as it will remove the 
gunge.

Don't adjust the rack damper too much either -- this is to reduce or eliminate 
shaking at idle, not a slow surge, and if you screw it in too far, it won't 
start cold.  

Peter

So, yesterday, I got to leave work a bit early.  Since the weather was
really nice, I thought I'd drive my 82 300D home instead of the usual
company test car.  I'd have a bit of time to explore why the fuel gauge is
unreliable.

A little background:  I bought this car two years ago because it would be
the perfect guilt free daily driver I could leave sitting at work for
weeks at a time and not feel bad.  Just a bit of rust, but a one owner
garaged car with 140k miles.  Trans flared, and it needed a bit of sorting
out.  The idle was crappy and it had no power.  So, it make this email
shorter, I'll summarize:  I cleaned up the lines the alda, replaced the
injectors, and installed a manual trans from a 240D (and loads of other
little repairs).  Suddenly I had a car that I've always wanted.  The engine
runs great, has loads of power, doesn't consume oil.  Its like my old 240D
on steroids.

So, fast forward to yesterday.  The car has been sitting for a while... I'd
drive it home every few weeks in nice weather,  I racked up a whopping 2500
miles in 2009.  And about 400 miles this year so far. (Including a trip to
the shore last weekend, about 150 miles).  I should mention the car sits in
a heated and air conditioned warehouse when its parked... possibly the best
conditions you could imagine for car storage.  (Thanks to the unfortunate
closing of Becker of North America)

I throughly enjoy the drive home... the car runs excellent.  Especially
memorable was the on-ramp to the Garden State Parkway, winding out second,
shifting into third, and drifting sideways for the last few yards as I
blast onto the highway at a crazy 50mph.  Wow, I remember how much fun a 4
speed W123 is!

But, that uneven messy loud idle is still there... just like it was two
years ago.

So after the hard run home, I set into work.  I had ordered up a new seal
for the tank sender a few weeks ago to be ready.  I removed the sender, took
it apart, and found it full of goo and crud.  Yuck!  I cleaned it all up, re
soldered the reserve wire, and reinstalled.  All is well.  But the crud got
me thinking... if all that stuff is also in the tank, it might explain the
crappy idle.  Perhaps there is alge, plugged filters, etc.  I remembered
back about a year ago when the car stalled out on me after taking a
(another) fast on ramp with only a bit of fuel in the tank.  I decided I
needed to replace the tank screen.

So this morning, with rain in the forecast, but the sun in the sky, I went
to work.  In the basement, in my collection of parts I never used, I found a
new tank screen and the fuel hose that attaches to it.  And some nice german
hose clamps.  I ran to the home-disappointment, picked up a yellow 5 gallon
diesel can for $10.  I climbed under the car, and did the dirty deed of
disconnecting the fuel line running from the strainer and feeding it into my
new diesel can.  The 5 gallon can wasn't enough, so an empty simple green
bottle, and my oil drain pan collected the extra two gallons.  Just enough
diesel ran down my arms and on the driveway to make this job especially
miserable.  As I reached for a 19mm wrench to remove the fuel line from the
strainer it started to rain.

So, the strainer came out with the hose and much to my surprise, it was
perfectly clean.  It looked about the same as the new part I had.
 Disappointed with the effectiveness of this miserable job, I installed the
new strainer, clamped up the hose, and poured the 5 gallons back into the
tank, along with a can of diesel purge (just because I found it on the shelf
too).

So, now I need some advice on how to continue with this idle problem I have.
 Here are the symptoms:

-Engine starts easily cold, but surges between 500-750 rpm at about 20
second cycles until it warms up a bit.  It fires on all 5 cylinders the
whole time.  This is worse in the winter, when the car will sometimes stall.
-At warm idle, the engine fires on all 5 cylinders evenly, but is

-There is no blowby
-There is no oil comsuption
-There is no excessive smoke
-The injectors I installed two years ago were new from the MB dealer, not
the questionable bosch rebuilds.
-This problem existed before the transmission swap, adla tweeking, etc.
-Valves were recently adjusted, filters changed, etc.

My next step is to carefully check the timing chain for stretch, and see
where all the adjustments that are possible are sitting.  So, after all this
writing, if anyone is still reading, here is my question.  In what order
should these adjustments be performed?

-Idle speed
-Rack damper bolt (which is old but seems good, but I'll replace it anyway)
-Injection timing

Do you have the updated rack damper bolt?  The new ones are gold  
colored and are SIGNIFICANTLY stiffer than the silver ones.


You shouldn't have to mess with idle speed.

What about the primer pump?  Do you see any air bubbles in the lines?

Rack damper bolt looks old, but is gold through the oxidation I think.
 I'm going to replace it anyway, as adjusting it isn't very effective.
 After more tinkering today, its slight better.  But still not good.

Primer pump is new.  I'm going to investigate possible air leaks in
the fuel supply... the rubber hoses are all new, but there are some
other hoses and fittings around the injection pump to consider.

I checked timing chain stretch... its almost none, perhaps 1 degree.
The tensioner, on the other hand, didn't seem very stiff to me.  I'm
going to compare to my 300SD and consider this a possible issue.

Thanks for the tips guys,
Jaime
