I am replacing the injectors on my 300 CE 91 - 104.980 engine. I've ordered the injector seals and injector insulator + O-ring to do a correct replacement job.

I am looking for the MB tech page related to the fuel injector insulator removal / installation (not the 07.3-6520, only related to the injector) to know if MB recomends to put back the insulator + O-ring with lub or dry?

If any one knows or have the CD...

Thanks.

I just bought a 1988 300CE from a friend that went to the north shore of Oahu. The car is great but has a fuel mix problem I think. Do you have a good indy mechanic in Los Angeles? I'm going to try to get the car over to Enrique in Tarzana this weekend. Its got 100K on the clock but we figure its around 125k miles. I have lots of the papers from the original owner and what my frined did the last six months he had the car. The injectors and plugs and fuel filter need replacing. Everything in the exhaust may be original. I'm attempting to get the motor internals clean enough to pass smog. And so it runs better.
Let me know how it goes with the injector replacement.

So I finally had to put a little bit oil on the O-ring to have it fit into the hole: to hard without.

Sorry for mechanics recomendation, I am doing all myself.

First impression after injector + insulator and O-ring change, and mixture adjustment, the car had a better response to throtle:

- significant at lower RPM (feel more torque under 2000 rpm),
- on the highway in 4th gear, at 60 mph,

basically a better response (less lack) and better acceleration.

Need more time to see if MPG is improved (I had a bad one).

Still have to fix other problems...

Sounds good. I am going to do most of the work on this car as well. Will only take to Enrique for diagnosis of problems and for some work if needed. I think its much more important to perform the work myself as time and money permit. I have worked on cars and trucks years ago. Once helped with the install of a MBz 300 Diesel into a Land Rover 109' series 2A project that also had all modern Range Rover british police spec running and driveline gear. Amazing truck. My friends built three of them. All paid for by importing mint condition classic 109's into the US from Switzerland. The one I helped build is serving as daily family driver in Canada.

Thanks for letting me know all about the injector seals. Let's compare notes on our cars. Thanks for writing back.

BTW, this is my first MB also. We did have a dark blue MB Diesel sedan when I was a kid and this 300CE I have reminds me of that car.

Also, which fuel are you using? Are you passing smog? How many miles? I checked the carfax and it appears that my car actually does have 110k miles. Is you're 300Ce a daily commuter or get around town car? Mine is for picking up my two sons from camp. Then in September I might restart my decorative painting business. Maybe I will use this car. Hopefully I wont have to go back to painting right away.

Regards,
Jason
