84 300SD OIL HOSES/LINES

Are the couple of hoses at drivers side of what I think is an oil cooler are those the oil lines? These hoses are like a hydraulic line, alterante between rubber and preformed special metal fittings and shaped metal lines. They appear to be a pre determined length and appear to go back near the trans. If so are they easily replaced? Cost and availability of the lines and do you have a how to guide? I recently used your ignition switch guide and replacement parts. Thank you it was quite helpful. One other question is the oil pan and gasket available through you?

617 Diesel Injector Lapping Procedure

As I continue my quest for perfect 617 Diesel Injectors & truth I have just learned today that I need to have the internal surfaces of my injectors lapped to remove grime & build-up. . .

Is this something I can do myself (lapping the surfaces) if I take on the task of re-building my 617 injectors w/new Monark nozzles?

How would I do this?

thank you & Happy New Year,

1980 240DD Transmission Rough at Start

I have a 1980 240D sedan with an automatic transmission. When I start the car and drive it first thing in the morning, the transmission shift from first to second gear is rough, it snaps my head when it shifts! However, once I have been driving it for about 15- 20 minutes and it's warmed up, the shifting from first to second is much smoother and about the same for the other gears. Is my transmission having a problem, or is this typical for a car of this age?

1981 300SD Low compression #1 cylinder

I finally got around to checking my compression and found (the car has 300K+ miles on it) all cylinders had 280-325 on the compression EXCEPT #1 which I checked 6 times with different crush washers and could never get over 160.

I'm thinking I need to recheck my valve clearances one more time. What else can I look for to try and figure the problem?

1981 300SD Oil in alda line

I was troubleshooting my 300SD for low startup torque (I have already adjusted the valves, rebuilt the injectors, etc) then I went to the alda. I removed the banjo bolt from behind the turbo but it wasn't all that dirty. Then I removed the bolt from the side of my alda and engine oil started dripping out. I don't know much about this thing but I don't think this is right.

I saw one of these for sale on this site. Is this something a shadetree mechanic can change?

1984 300sd engine keeps running.

My 1984 300sd will keep running after the key is out of the ignition. I do have a new shutoff valve to replace, but have not gotten to it.

Well, I figured out why the engine cuts off some times before I get the hood up. When I'm getting out of the vehicle I tapped the brake and it killed the engine. I do this with regularity now. Has anybody heard of this? And if so, is it still my "shutoff valve" or a vacuuum booster to the brakes?

1984 300D still very slow

I've followed along numerous posts on this subject and followed instructions where I could, but my car is still a DOG.

I have performed all of these fixes yet not realized much difference:
-Cleaned banjo bolt
-Replaced air/fuel filters (many times)
-StarBrite anti-fungus fuel additive
-Replaced some vacuum connectors (not the 3-ways, just the small pieces - I'm poor, but working on it)
-Replaced brake booster vacuum line - it had 2 broken nipples.
-Replaced vacuum switch levers (the two plastic things on top of the valve cover - whatever they're called)
