Good place and price for diesel injectors? - PeachParts Mercedes-Benz Forum

I have a noisy injector in my 85 300D turbo and I was thinking about replacing it. It runs good otherwise but the noise is loud and annoying. Does anyone have someone who they can recommend that they have had a good experience with and got the best deal on new injectors? Should I replace all of my injectors or just the one that is noisy?
Also can you use regular sockets or wrenches to remove them?

lietuviai,

Email me, you might want to wait a week or so and try out one of the ones I'm rebuilding and LMKWYT, I'll give a helluva deal on it of course. I have a webpage of these up, but not quite ready to push-off.

Already have one customer waiting for a balanced set of five, but I have enough that I could send you one out of the few batches I have.

If you know which one is the culprit, simply remove and disassemble it and let the parts spend the night in a can of old fashioned, caustic carburetor cleaner. Not the simple solvent, but the nasty smelling stuff that comes in a paint can with a parts tray.

After the overnight bath, lift the tray out and dunk it into extremely hot water, then remove the tray from the boiling hot water and blow off all parts carefully and thoroughly with compressed air. Reassemble and it will be good as new.

If you try this with ALL the injectors MAKE SURE YOU DON'T INTERCHANGE ANY OF THE PARTS!

Good luck,

Thanks for the great suggestions so far.
whunter, are they new ones and have you tried any yourself?
TomJ, I'll email you.
Larry, I've thought about taking the culprit apart, but if any of the parts are worn out, such as a spring, which I think it may be, I may still be better off buying a rebuilt one. What are my chances that it may be a worn out injector? Should I then just replace them all as a matched set?

The best bet would be to simply replace them all with a matched set of rebuilds with NEW nozzles, not reground. Then its a simple R&R with minimal downtime. Everyone here seems to think injectors last forever but my experience has been they degrade after 100K. Having done new (rebuilts) in two other vehicles with excellent results I highly recommend replacement. RT

Well I guess I'm way overdue for new injectors in my car since I've got over 212K miles on it and the injectors as far as I can tell are original.

Hello lietuviai

I agree with rwthomas1.

I am searching for another supplier of NEW injectors.

My old supplier retired and sold out to a mega chain store, they scrapped all his horded 48 years of stock; and all they have is rebuilt, not even calibration matched sets.

I have replaced hundreds of diesel injectors with rebuilt calibration matched sets; they are superior to uncalibrated unmatched sets, and you would be amazed at the difference when compared to home rebuilt injectors.
As stated; it will also minimize down time for the repair.

Violent agreement: Be sure to get a calibration matched set with NEW nozzles, not reground nozzles.

Diesel fuel injectors; like any mechanical device do degrade over time, even if you go to extremes by installing a rack of laboratory grade secondary micron filters for super purification, this will make them last longer, at the price of expensive filters and constant changing.
