I've asked this before, so I guess this is an update. My 79 240d takes forever (5 to 10 seconds) to show oil pressure. Kent asked if I'd changed the tube o'rings in the oil cannister.I did, but thought maybe I should pull it out and double check and make sure they were good.
The o'rings were fine, but there was no oil in the cannister.Shouldn't there be oil in the cannister after the car sits for awhile?
What holds the oil in the cannister!?
Anyone know?
It looks like I might have a vacuum leak. After turning off the engine via the steering column the engine still runs for about 2 seconds. If I press on the diesel pedal the engine will actually speed up a little then shut off. I would would like to know: Is the system under positive pressure or negative pressure? How do you test the fuel pump stop diaphragm to see if it holds pressure? Also the door locks still work but the brake booster isn't as effective recently as I have been having these problems.
I found that there is a lot of engine oil droplets coming into the intake manifold...and think it must be bad oil seals in the turbo.
I am working through 350SDL issues and found the solid hose broken that goes between the air intake (pressure side) and the mechanical accuator that opens the waste-gate. I am assuming that this has caused the previous drivers to drive it over-pressured. Would that impact the turbo oil seals so that they could now be leaking into the intake air? Are there other things I should check knowing this has happened?
Indicator lamp stays on. 10.5vdc at #5 glow plug. Wondering what steps to take next.
Thanks!

I have an 81 300d that I was running on BIO. It was loosing power and stall under a load. SO I removed the injectors cleaned replaced nozzles with monarks, bench tested and re-installed. Car ran then stalled and will not start. I drained the tank and filled it up with diesel. I replaced the fuel lines, filters and lift pump. Also replaced the glow plugs with monarks. Then did a valve adjustment. Changed the o rings on the injector pump, checked ALL banjo fittings and lines, replaced copper washers.
I have an 83 300d. I removed the panel below the steering wheel and found a vacuum line simply resting against the back of my brake pedal. I raced the line and it runs through the firewall into the engine compartment. It is connected to the "T" that is on the bottom of the transmission modulator on the rear of the fuel pump. The other side of the "T" runs to the lower right side of the 5 way connector located on the valve cover. That is if it is viewed from the front. Does anyone know where this vacuum line is supposed to go.
I've been experimenting with different electric fuel pumps and fuel line plumbing, running straight WVO. Last night an electric booster pump I'd installed down by the tank burned out (again! argh-can anyone suggest an electric booster pump that can handle WVO without burning out!?), and the car ran dry (I was trying to limp it home).
I own a 1983 300SD. The standard exhaust system has the muffler in the rear and 2 more or less rectangular shaped mufflers on either side about halfway between the front and rear axle. They look somewhat like "outriggers". What is the purpose of the latter 2? What are the drawbacks if I were to remove them.
Thanks

I see the engine mounts from under the hood. I also noticed what looks like a mini-shock absorber. Is that part of the engine mount? Is it important? How can you tell if it is working? The engine vibrates while in idle but it has no effect on that mini-strut. The rubber mounts are soaked in engine oil but they are not torn. I'm not sure how old they are since I just got the car 1 month or two ago. Mercedes Source has a neat engine mount kit that I can buy but I was wondering if aside form the two rubber engine mounts and the transmission mount, if the mini-strut should be replaced?
Kent and all,
My youngest son has seen the light! After his 4YO Kia Rio broke a timing belt in Nowhere, Tx. he finally figured out the old-stogey Mercedes Diesel that his dad has driven for 305,000+ miles is the way to go.
He's got mechanical skills but no garage (other than Dad's)and he's on active Duty with the AF Reserve, right now at McCord AFB but soon in Alpena, MI and then on to Charleston for several months-Germany after that.
