I have an 82 240 d. This is my first car.When I aquired the poor girl she was in a terrible state.She wouldnt go over twenty.I knew it had problems but I saw the potential.So I bought it for $1000. The woman I received it from knew nothing about diesels , and at the time neither did I. So I got myself a Book. After familiarizing myself with the characteristics of a diesel.I decided to get a little dirty. I like to think of myself as a sensible mechanically minded individual ,and I dont trust mech. shops. So I began my analysis and repairs imediatley.The problems that I encountered are as follows.
1.The Racor filter had been completley bypassed.
2.The glowplugs did not give heat .It would do 15 revs. before starting ,replaced those now its 1 rev.
3.the fuel intake line was smashed nearly flat do to someone bottoming out.Replaced that metal section with rubber line.
4.Every rubber fuel line had a leak even the 5mm. injection lines.
5.The gas tank I drained and removed from the vehicle.Then I removed about 3 cups of solid algae chunks.Then I powerwashed the tank and dried it with a shop-vac duck taped to it.
6.Multiple bad fuses made it necessary to change every one.
7.Power steering pump drained constantly.Rebuilt it , good as new.
8.Hazard swich failure, replaced it.
9.Broken grill, replaced it.
10.Numerous scratches. Rubbing compounded the whole car. It looks great even looks like a super high polish.The interior was in really good shape to begin with.
11.scratches on the hubcaps. I noticed that the metal beneath was polished crome so I used paint remover on them and now I have crome mbz caps.
12.All new filters of course.

13. HERES A GREAT ONE. during my time under the hood I presented myself with the dynamics of the fuel primer. I got A universal fuel pump hooked it up to a toggle switch next to the engine. Now when I replace the filters or the incjectior lines I dont even have to crack the lines. I just did my injector lines so when I did I just put the lines on flipped my toggle switch waited a minute turned the switch off then she started up like I had just driven her.
14.Radio didnt work, inserted cd player, equalizer, amp.,replaced broken antenna, and two 8in bazooka tubes.

Now my last remaining problem is that I noticed that the block was wet so I turned it on and watched the engine. I found that the fluid was coming up out of the injectors at a very lite rate. The car now runs great she goes 75 with the best of them and still hides a little more behind that. My book didnt have many answers for me Ive gotton this far myself but I would appreciate any proposed solutions and or ant other tips on improvments I could do to allow my vehicle to be all that it can be.

The injector leaks could still be the small return lines at the tops of the injectors ,if you did not use the Good Braided Hose to replace them ,or the Nozzle tip shields ,or the Prechamer seals (Shims ) at the bottom in which case you will need a sppecial tool to remove those Nuts and have to remove the glowplugs to remove the Chambers which require an additional tool. Squirt some Brake Cleaner on the suspected areas then dry off with compressed air, then start it and watch closely to determine where exactly you are leaking. As for the poor performance have someone push the foot feed to the floor (engine off) whilst you see if it is getting full throttle at the injection pump between the block and pump at the back you can see whether the lever actually bottoms out on the limit screw . A valve adjustment would also be recommended if you have not done so .

forgot to mention that the full lthrottle travel test is best done with the engine shut off.

good job so far. as yogi berra said "it is amazing what you can see just by looking".

I did use the proper braided german lines, and I can see that the is coming up from directly under the injector.It runs from the injector cavity then down the block.I will check the prechamber seals (shims). Thanks for the help fellas Ill be checking back to see if you guys come up with anything else.

easy to double check the small return lines. these even though new might be thr problem. the leaking of the injector is not a normal thing to have happen. so i recommend double checking your return line.
