Does anyone know a good place to have injectors rebuilt? I am planning on getting new monark nozzles, but I don't have the tools to pop test them. I am not sure where I can get this done or how much people generally charge. I've got a 85 300d

There's a guy on the forum who does this kind of work by mail. Another option is to look in your area for a diesel repair shop and ask them.

Any chance you know how to contact him or his name on here so I can PM?

If I'm correct, you'll want to contact C Sean Watts on this forum.

You are correct !!!

Drizzy,
Welcome to the forum !!!!
You will find that we are a friendly group, always keen to help out a fellow MB owner!!
The combined experience & knowledge about MB diesels on here is hard to beat!!
Just remember that there is no such thing as a silly question!! Some of the answers you get maybe though!!

You are making the right decision to look for some one who knows what they are doing with regard to injectors.
While DIY is very doable, those who work on these injectors regularly develop skills that others may not have.

Yep, DIY is in my DNA, but there is definitely a learning curve on rebuilding the injectors yourself. Sean Watts is a good guy to deal with.

Just curious, is your recommendation of CSW based on personal experience or just plain hearsay? Seems unlikely that a chap in Oz would get his injectors serviced in North Carolina, USA.

Gus at Pacific Fuel Injection, Burlingame, California. He installed my new nozzles in the bodies, adjusted pattern and balanced for pop testing, etcand adjusted 10bar over which is common practice for higher mileage engines. Been doing this work for decades! I purchased a rebuilt injection pump for a bmw 2002 tii in 1981 from him. He has some very cool cutaway injection pumps in his shop so you can see the inner workings -these pumps are very intricate

Anybody has sent injectors to Sean Watts recently? I have tried to PM him but haven't got a reply.

Try calling him at 919 828-5221 Leave a message if he does not answer and he'll call back. Sean is really helpful and will spend the time to talk to you. I bought nozzles from him and very happy with the nozzles and the technical help provided.
