pull engine to replace injector? - Benzworld.org

A friend of mine has a 99 E series turbo diesel, one of the injectors is leaking and needs to be replaced. Her mechanic, (not a dealer) told her the engine must be pulled to replace it. That sounds a little extreme to me. Is this true, if not is it a big deal?

I could be mistaken but it looks like this is another person to be brought to the public's attention.

I seriously doubt Mercedes would design a car whereby one would have to pull the engine to remove/replace an injector. Is this mechanic willing to put this in writing.

Sidenote: I would cut a hole in the member that is preventing removal and then close the hole through various means.

Joe.

I dont know a lot about this subject, but it sounds fishy to me. Have her take the car to another mechanic.

I've known of a few shady mech's that take loose motor mounts and manipulate the position of the engine so they can work on it as "Pulling the engine". Find another mechanic!

every 99 e class diesel i have worked on the intake manifold has to come off to reseal the injector. it is pretty common for the injector seals to leak, not that expensive of a repair. off the top of my head i think its about 3.5-4.0 labor. i would also rec replacing all the plastic fuel lines around the injectors because every time you touch them they seem to leak or break.

I agree with benzmech-having been a M-B tech for years, I can tell you the only thing that needs to be removed is the intake manifold

to remove/reseal the pump yes the intake manifold needs to come off. the injectors themselves are under the plastic cover on top of the head.

Actually, I can think of something else that needs to be removed. The nut on the other end of that wrench. While field servicing is often a poor second to quick assembly, I can't see an engine needing to be removed for something that might need service under warranty.

You mean they alter the postion of the engine mounts to make it look like the engine was removed?

Original poster, follow everyones advice and tell your friend to get a second opinion. I could not imagine the engine having to come out with a V6 engine to change an injector let alone an inline 6.
