Howdy all!

My 82 240D has started acting up . . . about two weeks ago, I drove 3.5 mi to work, then 2 hrs later I drove home, loaded up the car, added 2.5 gal of filtered WVO to the half tank of diesel, then I made a 200 mile run to Phoenix, and left late, so I kept it running hard to about 75 - 78 mph . . . on the way back I stopped and filled up with diesel, and was running the A/C, and slowed down to about 70 - 75mph, the next morning I noticed that it was starting harder . . .

The next week I left work, and drove 3.5 mi home, loaded up the car, and added 1 gal of WVO to 2/3 tank of diesel, then left for a 90 mi run to Tucson in about 10 min . . . It still started hard even though it was up to 70c, and I glowed it till the light went off . . . I backed out of the drive, and drove 100 yards to the end of my street, as I was taking off, at first it seemed normal, but as I shifted to 2nd gear, it lost all power (well it doesn't have much to start out with!) and I saw a cloud of whitish smoke/fog, I did a quick U-turn, and headed for home, it perked back up and ran normal in the drive, so I took it to Tucson . . . 75 mph it ran fine.

When I came out of Sportsman's Warehouse with my new Ruger SRH Alaskan 44 Mag! I glowed and started it up . . . almost through the parking lot, it died, with a cloud of whitish smoke, I cranked while I was rolling to a stop, and still no joy! I checked and there was fuel in the filter, and then it started, and we drove about 15 miles and stopped for fuel, I decided to leave it running . . . at an idle it seemed to be a load clacking noise, but it quieted down as I increased rpm, drove it home . . .

It still starts hard, and clacks loadly at an idle . . .

I changed my oil about 1500 mi ago, checked valves at same time, all were still in spec from the last time I adjusted them 10k ago . . . oil pres is about 1.7bar at idle when warm/hot.

I have no record of any injector work ever being done on this . . . could it be it just needs new nozzles? Oil consumption has slowly been climbing . . . when I first got it, it was about one qt per 1kmi, now it is about one qt per 750mi . . . does not seem to be fuel in the oil, but I noticed Sat that I had driven it about .75mi and left it idling, and there was a slight blue haze around the car when I came out!

I have in the past mixed in about 1-2 gal of wvo to the diesel, no problems, but the stuff I put in recently, was thinner, seemed more like the thickness of regular diesel . . . going down the road it runs normal . . . I have ordered a compression tester, but thinking that the injectors need some help . . . and possibly that the thinner WVO contributed to the problem.

So what do you think?
