........sounds to me like somebody.........with the proper pop tester.........and knowledge..........might have a service to offer...........???

Are they not a wear item? I mean, can you imagine just how many time they have popped in say 200,000 miles, especially if you are a person who is in stop and go traffic with a lot of idling. It would seem to me like they would wear. This is the first diesel forum I've been in where most people seem to not want to change injectors.

if you look at my other posts regarding injectors you will see, that spray pattern and pop doesnt tell the whole story on injectors, I had two different bosch service centres test injectors in front of me at no cost and injectors tested great, for pop test and spray pattern! put bozio nozzles in myself ,my diesels a 99 E300d cured the noisy idle and quieted her down to off the lot style 7 yrs ago totally impressed !

Can you post a picture of your homemande pop tester and explain how it works? I would love to do this myself.

Thanks,

Scott

Let's say one has the pop device and pressures are mismatched... where do you purchase shims to correct this difference?

I am very interested in the Bosio nozzles, but I was wondering do you guys check the pop pressure of the new nozzles? I have heard that even new nozzles can have incorrect pop pressure. As far as making a home made pop tester there is some interesting information about this on the infopop site in the SVO section.

Thanks,

anyone know how to use a diesel pop tester?

The FSM is very specific on how to test them for wear and to make sure their functioning properly, regardless of mileage.

I did not want to pay $180 to get new injectors but to me, it had to be done. Below is a picture off the old injectors. #3 and #5 are the worst. Would it make sense that back when I did my compression test, that #3 and #5 had the lowest compression? I also had to tap the #3 and #5 injectors out when the halves were dissassembled due to carbon build up.

Picture #1 is of the old injectors. #1 is at the top and #5 is at the bottom.
Picture #2 is of the #3 injector.
Picture #5 is of the #5 injector.

What do you guys think?

They're in the same ball park as gasser multiport injectors to me... pintles get clogged, fitler at the top does, etc.

Every 100-150k I'd do them. I have a few extra sets to sell off then I can experiment.

I just wish I knew where to buy that adapter and gauge to build my own pressure tester... and of course, where to get the shims!

While I admire anyone who is gung ho enough to want to service their own injectors or build their own pop tester there are limits to what I would consider a good use of time. Diesel Injection service shops spend a lot of money on equipment and time using it. They also charge very little money to clean and pop test a set of injectors. I let them do my injector work. They know better than me what correct spray patterns look like and what to do if they aren't. I think I paid $50 to have my injectors cleaned and popped last time I had it apart. RT

Was that $10/per injector or $50/per injector?

I don't have a problem rebuilding with new nozzles and paying someone to pop them only for me.

I'd imagine a good diesel injection shop, or a Bosch service center could get the shims. Would be nice to be able to purchase them online and just have them shipped.

I like the idea of having my own tester, especially with the WVO stuff. Its a fun tool to learn which makes it fun for the hobby. And as long as I take care of it and don't damage it, I can sell it in Ebay when I'm done.

Before installing the brand new Delphi's on my 6.5 I tested them and one of them had something in it as the pattern was bad. Took it apart and cleaned it and then it was normal like the others. Another nice aspect of having the tester.

I have about $50 worth of heat shields in the driveway. I tried the Bosio knozzles without success. I had a warm idle problem that I was attemting to cure.
After about 350 miles I took the Bosio injectors out to be tested (another $50).

1) The Bosch shop found several different spray patterns, one of which was correct (According to the MBZ manual and Bosch a 0 degree spray pattern).

2) The part number for the application for a 300 D turbo is incorrect. Diesel Giant stands by the part supplied is correct, however the Bosio knozzle box says compatable with Bosch 0 434 250 120. The correct number for a 300 D Turbo is 0 434 250 110.

3) Yes I had some leakage. The Bosch shop recommends a little less torque than more during assembly. I torqued mine about 5 pounds less than reccomended and now I have no leakage.

After all the valve adjustments, checking the timing chain and various sets of known good injectors I've tried a 1/4 turn of the rack dampener did the most to smooth out the idle. Not that it has cured all the warm idle problem, it helped the most and made the warm idle problem tollerable. After about $350 dollars of attempts that equals about $1400 dollars per turn on a bolt! All and all I'll stick with original equipment Bosch. I have a new set of Bosch in hand but I've been stuck with other honey dues. (I guess I better get at putting the new water heater in the house. I hate my wife telling me to take a cold shower and that's my only choice )

Diesel Giant was very gracious about the return and I have no problem dealing with them in the future.

Good luck everyone.

That's another problem with the Bosio nozzles. Everyone raves about them but they HAVE NOT stood up to the test of time.
