Ive ordered a number of different types over the years, They supplied whatever number I've needed--You Have to give them the actual Nozzle-Number...

I believe they will also supply out a complete re-built injector set if needed,--costs though...

All the Bosch Ive ordered from Merlin Diesel have been made in France...

The Delphi nozzles (Lucas/CAV et-al) have also been made in France. Delphi make all the usual suspects and are in equal quality to a Bosch France/Germany nozzle...

(Lucas/CAV/Rotodiesel/Delphi are OEM for a lot of European vehicles....)

Only set of Bosch India nozzles I had came from a different Co, (Help-Today) and needed a clean as I had issues when fitting one--Production dirt maybe....?

Been perfect ever since though in my 190D 2.5...

.

On reflection however, even though there are no issues Now with the Bosch India, I would still go for Delphi or Bosch France, from Merlin-Diesel

BTW, and very often forgotten when removing/replacing an injector....

You MUST replace the 'heat-shield' washer Every Time, Even if you had the injector in there only an hour and need to remove it for whatever reason, the washer Must Be Replaced--Failing to do this can cause nozzle damage, as the washer de-forms during installation to make the seal--A poor seal can easily overheat and 'blue' a nozzle.....

Thanks for sharing your experience Alastair, you know your injectors!

I originally got some german made bosch nozzles from merlindiesel a year ago. I ordered some more and they sent me indian nozzles, even after I asked for german ones. Now they won't answer my emails about it, and they tell me on the phone that it's tough titty for me. So I'm not impressed.

But, Alastair, are you saying they should be OK now, the indian nozzles? Is it worth it to hassle them and/or do a chargeback on my card and get Delphi nozzles?

Sorry for all the questions, but one more... What is your opinion of Monarck nozzles? They're available here in the US for about $20 each, and I think I've heard good things about them.

Thanks,

OK, this might get me in trouble, and, before I get into it, let me say I know it's not the 'correct' thing to do. But if you're in a tight spot....

I R & R my injector shields / crush washers / heat shields.

As far as I can tell, they're made to crush down when you tighten the injector on them. Once they're crushed down, they don't bend back, so that's why you need to replace them.

But I took a small socket and put it through one side (that needs to go up again from being crushed down) and a big socket on the other side that fits the outer edge of the washer, and use the channel locks to squeeze them together so that the inner rim that seals off the injector is pushed back up.

I've done this and then taken them out a while later and the nozzles seemed fine. Will it last long term? Don't know, but I can't see why not. Eventually, if you did it lots of times I'm sure the metal would fatigue. But since they're made to bend, bending a few times is probably not going to bugger them up.

Whatcha think peeps?

Sorry you have a problem with Merlin-Diesel.--Personally, I wouldn't bother going down the 'Litigation' route, Just for the sake of where they were made, when you haven't even tried them out!--IF they are faulty, Then you could always send them back for replacement/refund etc, as you then have a valid reason....

.....I guess I can understand from their point of view (as they supply out probably hundreds of injection-parts/nozzles per week, and probably never heard of someone sending parts back due to where made...), that they may think it silly to replace a nozzle set on this basis--

Or on A Vague Possible Maybe, that they are faulty, even though they haven't been used....(And JUST because they are Indians!)

Personally, I have had excellent service from Merlin, and found their technicians friendly and very helpful on the 'phone....

From experience and from a friends experience, If an Indian Bosch nozzle is 'faulty' its faulty 'Out Of The Box', (maybe through dirt etc,) and does not go on to develop a fault soon after use if its OK when fitted/tested and set-up....

As I have Indians in my 2.5D, now maybe 8?K miles on them with no issues apart from the initial cleaning issue, I would at least give those nozzles a try, Maybe give them a good flush out with filtered fuel before assembly into the holders....

I have no experience with Monarch nozzles, Never seen any- But worth keeping in mind, is this--

Did Mercedes-Benz Ever use Monarch Or Boso as an OEM supplier of diesel fuel injection equipment?--Just 'cause its 'Made-In Germany' doesnt Guarantee perfection!

--They could well be excellent nozzles, I don't know...

Both Delphi/Lucas/CAV and Bosch are OEM to Mercedes-Benz, and Boso/Monarch are not as far as I'm aware.......

I'm using one of the indian bosches - it was fine out the box, so maybe it will stay fine. We'll see... Thanks for the input.

I put in new bosios in my '85 300D. More power, easy starting, mpg went up 3 to 29. 6 months later: rough idle, blue smoke, ....where can you get good OEM Bosch injectors?

I have had very good results with the "Monark" injectors I got from Sean C Watts. He installed new nozzles and balanced them for my 79 and, later for my 85 240D. It was under $140 per car with shipping.

pdrayton · #53 11-03-2008, 12:34 PM

Stevo, how many miles you got on those Monarks, and have you pulled them to see how they spray?

Any idea where to buy them direct and balance myself? Thanks

bgkast · #54 11-03-2008, 01:07 PM

Sean C Watts will also sell you just the nozzles for around $20 each. I am about ready to order a set my self.

I may have only put 10 or 12k on my 85 and 6 or 7 on my 79 and they are still preforming fine. I'm sure the Monarks are available on line if you want to do the work yourself but I dont know exactly where.

New nozzles will 'settle' over time an need to be re-calibrated.. did you ever adjust your timing when you installed the rebuilt injectors?

there is a member selling bosch germany made 261 nozzles in the parts section

Mine have around 10-15k on them. Still running very well. Quiet as can be in a 603.
