Back up and check Thomaspin's site on running Diesel Purge through the system....... Hey moderators, maybe Thom's site should be stapled for permanent viewing?
Ran 2 cans DP through my 118k miles 240D last weekend and the car now runs smoother with better fuel mileage and zero smoke at start up. Wolfpack, pulling the injectors can open can of worms - including sealing of injector compression gasket, mixing up the parts and/or accidentally dropping one injector head-down on pavement. Larry Bible offers good advice - but you've got to assume he's working with fully equipped mechanics shop. Sometimes less is better than more. Last edited by 300SDog; 07-28-2003 at 11:31 PM. |

Pulling and cleaning the injectors may or may not work. You have no way to check the spray pattern and set the pop pressure. Both of these are critical to proper injector functioning. Yes, these cars were designed to be worked on and yes you can fix them "in a tent in the desert" But simply cleaning the parts and reassembling is doing the job halfway. Have a reputable injection pump shop clean, test and set the pop pressure. The difference will amaze you. They will also tell you if the nozzles/pintles are scored and need replacing. There is no way to check this or fix it at home. RT

After cleaning, the spray patterns will be very near what they were when new as will the pressure settings.
Have a great day, |

I borrowed a pop tester from a truck mechanic friend and tested 8 injectors. 4 had a nice even spray pattern and "popped" at or close to spic pressure. 4 had a poor pattern or low pop pressure so I replaced the nozzles (new ones) and tested them again. Nice pattern and up to spic pop off. I used a sheet of paper to see the spray pattern. anyway it was a fun thing to do where you can see the results.

Stevo,
Don't get me wrong, I'm not asking you to redo your experiment, but it would have been interesting to test them before and AFTER disassembling and cleaning in the caustic solution. I realize it's difficult to keep a vehicle off the road that long, but it would have just been interesting data. Have a great day, |

"I realize it's difficult to keep a vehicle off the road that long, "
Larry...Ya I know I should have and I wasn't even in a hurry. It looked to me that the guts of those injectors were so straight forward and that a good cleaning would do allot. When I disassembled them the bad ones were full of crud so I should have just cleaned all the parts and then checked them. I had ordered the new nozzles and was in too much of a hurry to see how they would check out..... Next time Steve |
