The Bosios nozzles i bought were made in italy, NOT india..I double checked.
They are performing great after 9k..but a lot more money than these monarks,
at the time, i never heard of them. The italians are actually in the same league as the germans when it comes to machining--thats my industry, and I am not italian.

Hello fellow grease monkeys. I wanted to give another update on the Monark nozzles installed in my 300d. I now have a little over 21,000 miles on the set and they still drive wonderfully. They seem to have smoothed out more and settled in, but no loss in performance. I am very pleased with them. I think one of the nicer things is that there is no pilot injection hole to clog up as on the bosios. Not saying that Bosio's are bad, ive read they have very good quality. I just like simple and basic, and these fit the bill. Anyone with questions, feel free to ask.

After installing and test-driving my 1991 350SD with new Monark nozzles I can tell you they are fantastic. I have had the car since it had 50,000 miles on it and now it has 105,000 miles and it has never run this well. I bought the cool pop tester from Mercedes Source and balanced the injectors myself with the provided shims.

There is no more smoke even with my foot to the floor, the idle is very smooth, and she has a lot more power. On the freeway at 85mph up a mountain pass (I64@Afton VA) just now I could have easily accelerated to 100.

I think that some of the lower-quality 100% biodiesel I used may have coked-up the old injectors and I doubt if the injectors were ever balanced as well as they are now.

My friends with MB diesels are neglecting their injectors. Some of them run B100, and some SVO. The manual I have says that with SVO you might need to clean your injectors every 12K miles.

Having ran both they're both high quality and would recommend each of them. Having said that i like monarch they're cheaper.

I like my Monarch nozzles and C Sean Watts is a great fellow to deal with.

How did the Manual say to clean the Spray Nozzles; with a chemical Purge or taking apart the Nozzles and Physical Cleaning?

I don't think it is possible to sufficiently clean the injectors with purge alone. I have tried it. You get to a point where the purge doesn't fix the problem. If you just let it go, and go, and go, your engine will shake itself to pieces at idle.

The manual suggests that you should remove the injectors and physically clean them every 12K miles if you want performance continuity with SVO. Mercedes Source sells a nice cleaning kit called TOP BRASS. I will get it when I need it.

After seeing my injectors after 50K miles of B100, much of it that had some glycerides in it, I can see why SVO would kill injectors after 12K miles. Not a bad trade-off considering the cost savings.

I haven't had as much luck getting hold of C Sean Watts as some of you have. I have not tried through this forum, but he replied to my first email and nothing on my second and third. I was just trying to get pricing. Maybe this forum is the answer. We'll see...

I'd try a PM. Ask him to call, perhaps.

Hello:

Same as the first - hessianimports@bellsouth.net

But I just sent you a PM. Hopefully that will work better.

What is a good source of shims? When I do this, I need to finish in one day to get back on the road and I can't wait to order shims.

C Sean Watts sells a Shim assortment.
If you access to a Shim Punch set I believe it is 7/16 outside diameter is the one that works (I bought a Shim Punch for myself). However the shim will not have the center hole in it and it you should make sure it goes between the other shims and the upper Injector Body; not against the spring or inbetween 2 of the shims.

Thanks
