checj the recent disscussions

i have been. i have searched but i havent come up with a good answer. i even posted my question in the other post thats going on but it didnt get much attention.

Recent experiance with this issue on my 87 300DT has educated me quite a lot. Here is what I did.

First, at the advise of another member, I poured about a cup and a half of diesel purge ( Redline or Power Services) cetain boost, injector cleaner/lube, into a large jar and connected a fuel hose from the jar to the fuel supply pre-filter and started the engine until all the diesel purge is emty in the jar then shut off the engine with your stop lever, or by key, either way it doesn't matter, just shut it off before you begin to suck air, then reattach your fuel supply hose and take drive for 15 min or so and then do the same thing again.

I did a total of three purges and I could not believe the difference it made. I did not know my engine could run so smooth and quiet!
My fuel economy went way up also.

I would try diesel purge before you go and spend lots of money, try $57 for each injector and then you would have to have them pop balanced too, also new heat shields.

If your injectors have well over 200K, you could be due for new ones, but try the purge first!

A friend of mine who runs the electron microscope lab at Central MI University has reported that PS and and I think most of the product's like PowerService, is mostly bio-diesel. The carrier is B100 with some cetane booster.

After bio-ciding the tank, I've run some B2, followed B5, followed by B30 mix. I'll be pulling the filter screen in bottom of the tank tomorrow for cleaning, then replacing both fuel filter's.

Can he inspect under a scope the India (and other Country) Nozzles and compare them with someones german nozzle and see what differences there are?

Yes, he has done this for us on the TDI forum. Here is a link to a couple of photo's he did for us on the TDI forum TDI Club the page contains 3 large photo's, so beware if you do not have broadband. I will email him and ask if he would do that for us here also.

We have several sources on the TDI club site for injector sales and upgrades, maybe some of the sources can help people here with our MB's.

I'm willing to help - esp if it is to expose rip-off artists...

but it is as availible time wise. Meaning - get the stuff to me to look at and I'll work on it as I can - may mean i can't offer the fastest turn around.

Also i don't do commercial work for free. vendors and folks selling stuff need to pay for any services rendered - in goods or cash, adn goods meaning something i can actually use...

Private stuff - no problem - drop me an email and we can discuss the details - i haven't examined any MB stuff and am not really familar with the injectors but i don't see it being much of a problem...

Thanks for the reccomendation oldnavy - I'll make sure the CMU alumi association gets your phone number ;)

Dooh!!! SEMO alumi association as a regular in my mailbox is enough.

i ran a diesel purge a few months ago and i plan on doing it again to try and avoid buying injectors for a while

I bought rebuilds since the internal parts of an injector do wear out over time and no liquid (diesel purge) will fix worn out metal parts. I would definitely invest in new injectors since they are not that expensive anyways. Then make sure you send them out to be adjusted and tested. Once you put them on your car you will not believe how much better your car will be running. You definitely will not get that with diesel purge...... trust me; I did both.

Look at some of my recent threads as I even have pictures of the old and new injectors. I was going through the same dilema that you are in now so learn from my mistakes. Screw the diesel purge. Don't get me wrong as I still use purge every few months but I will not use Diesel Purge to rebuild my injectors.

Kamil is correct in part part that injector noozle's do wear from the fluid and nothing will fix that, but keeping them clean will help prevent early wear spray problems.

I fully agree that any injector will need to be rebuilt, or replaced with new eventually.

Understanding where the line is that you draw to replace them is a bit fuzzy!

I was going to replace mine with all new injectors but tried the purge first instead. The improved difference purging made put for me the new injectors on hold!

I really don't think putting new injectors in now could make much difference, maybe I'm wrong but when purging begins to fail to make the huge improved change, I will then buy new injectors.

injectors are the cheapest thing in the world.... they are like 55 bucks each...

i will be doing a purge tonight. i am hoping i can get through till after i get my front tires and my insurance payment out of the way. about another month. i will be buying them for sure. how much are they new? 55 is for rebuilts ,right? thanks for your replies.

i got my injectors for 43.98 plus 15 core charge. Once I returned the cores I got my 15 per injector back. I know that two places sell them and I got mine from *********************** Our forum sponsor also has them.

if you do buy them make sure you send them out to be tested and adjusted

Kamil

I think I'd like to invest in a injector pop tester. My understanding is that the little washer that sits above the spring is where the adjustments are made depending on washer thickness.

You can set each injector perfectly to the next, sort of like gapping spark plugs I guess, and have your engine purr like a kitten!

I also read here in this forum, that new injectors need to be broken-in and that process can take much time!

Damn dude you must life on a diamond mine compared to me. lets see..

55 *5 = More than Half the cost of the whole car
55*5 = One Weeks pay NO KIDDING and that is before taxes.

welcome to how the rest live!

damn, how do you live on that ? i make about 1000 a week after taxes....... i cannot imagine making 55 dollars a week

tell me you are kidding ...... ???:eek: :eek:

Getting off topic but I believe that he said 5 x 55
lets say 275

It is a different type of work environment in Panama City.

Many minimum wage jobs exist.

ooops....now I see it. i knew that was impossible

I joined the USN in the fall of '63 and by the spring of '64 while at electronics school at Treasure Island in San Francisco Bay I got paid $35 twice a month. Do you how much a good meal was on Fisherman's Wharf in '64? $10 to $15. :eek:

When I decided to return to acadamnia, I entered a world of lowww payyy. I made more in junior high school than I do right now.
I left one job last month to go to a lower paying job.
Last job WAS lowest paying job I every had.

Boy, I sure miss flat rate pay.

well I can eek out a bit better than min. wage in my field even in this area. Just not much more in this area. I coach around 20 hours a week here. In the past it was more like 50 to 60. I'm like like those above who had to change jobs for varies reasons. All in all I took a 75-80% cut in pay when I had to move back here to my home town.

Butttt... I cant work full time away from the house. I'm like a single dad but with two 80 year old children to take care of. This takes a huge chunk of my time. I dont get paid in dollars for taking care of them.

Yep 80yrs! I am the family member taking care of my once full of energy and life parents. No violins playing a sad song here. Caring for them is a GREAT job and their worth it. Just hard on the pocket but I can live with that. Just gotta be wise with the ol' dolla.

god bless you. nice to see that people still do these generous things for the parents. :)

Back on topic.

Where to get injecter nozzles?

I want to get a different nozzle than those for the 300D. I want the ones for the same engine but used in commercial rigs etc. They had different nozzles. I do have the part number. My direct from India source is around 12 bucks/nozzle before shipping. Suspect I can get around same in US and they will most likely be from India too.

I read here many times that INDIA nozzles are really bad.

here is the actual post.... don't buy india nozzles

i called napa today and they want 138.38 for REBUILT ones.:eek: i put some hi-test in the tank and drove it on the freeway in 3rd gear. it seems to be running a little smoother. i would still like to start saving for new ones. what all is needed for a rebuild? i searched fastlane and european automotive and couldnt find the whole injector. all i could find was the parts to rebuild them. tomorrow i will run the purge as well as install a new shutoff valve. not to be off topic but,does anyone know what i can use to clean the oil out of the vacuum lines going to the switch? keep the info coming. thanks for all the replies

Kmaysob:

Buy new vacuum hose! It's cheaper than the time and the money for the cleaner you will use to clean them!

Vacuum hose really is cheap! I'll bet that for under 3 bucks you can replace all vac hoses in your car!

i cant find anyplace to get them. ill check autozone and bap but other than that i cant find them anywhere.

also i dont think the old ones are original because the return nossles do not line up which tells me they have been taken out before

click on the button that looks like this

I have read elsewhere in here that when you get down to it all you can get is India injectors and parts. If you get something german your just lucky.

Yes, this is correct. Out of about 20 nozzles I ordered, all but one were the India ones and the other was French and it's not much better than the India ones.

Also, the local injection shops have the German ones still, but they want $65 each (just for the nozzles) so I assume that's why they still have them in stock. Once they're gone though, no more.

Am thinking that it may be worth it to acquire some of the new German ones that are still in stock locally even though they're double the price, sometimes what works is WORTH twice the price.

Of course, like everything else, YMMV. Remember, this is just my opinion and opinions are like......, well, you know.

well i ran the purge today and it runs better. i still have a noisy injector but it runs little better. i am aware of fastlane as i have ordered from them many times. i have never seen a whole injector on their site. does fastlane carry the german nossles? if i read it right i can find the noisy injector by loostening the injector lines one by one till the noise quits. is this right? thank you all

If you don't want to make a mess cracking the nuts, use a long socket extension and put one end to your ear and the other on the injector........WOW!!!!

today i turned up the alda and it seems to run much smoother. i havent checked to see if the injector still makes noise but it definatly runs better and if faster.
