leaky injector pump
I have a leaky injector pump on my 1987 Mercedes 300 SDL. A local Mercedes mechanic who doesn't have the machine for fixing/resealing the pump, but would eyeball it, carefully marking levels, would do this for $330. Someone recommended a very good mechanic to me today, who doesn't do this particular fix, but strongly advises me to have it done by someone with the proper equipment/machine.
If that's true, I'm looking for someone to fix or rebuild the injector pump somewhere near Los Angeles. Does anyone know of a reputable place? Thanks |

He has done several pumps for me, and does an excellent job at a reasonable price.

That's an impressive collection of diesels. Does your 350 SDL have the reworked rods, and has it been trouble free? Thanks for all replies! |

Or would they be replacing the O-rings and crush washers while the Fuel Injection Pump is on the vehicle?

you have not said if it is Fuel leaking (usually the delivery valve O-rings) or Oil (leaking usually from the bottom plate, side cover or throttle or shutoff shafts).
I would not trust the O-ring job to a regular mechanic. If it is the Delivery Valve Seals/Fuel leak even if you do not do the job yourself you could look in the Repair Links and get some idea what needs to be done. The same with the Oil leaks.

Proper torquing of the delivery valve holders after a seal replacement is very important. There's a 3-step torque process to ensure that the sealing rings are seated and properly mated to the delivery valve holder. Too loose and the DV leaks, too tight and you run the risk of damaging the pump.
I have no idea what "levels" the first guy was talking about. R&R of the DV seals can be done with the intake manifold in place, but it's a massive PITA. More than likely, his labor costs involve removing and reinstalling the intake manifold for better access. If they're removing/reinstalling the manifold, changing the fuel supply hoses, and changing the filters for you, I'd expect the labor to come in somewhere around 3-4 hours + materials.

Thanks for the thorough response. It emboldens me to follow through on my instinctive impulse to take the car to the second mechanic. He seems to have a comprehensive picture, and he did mention removing the manifold.

If you're handy or mechanically inclined, don't be afraid to R&R the DV seals yourself. It's an afternoon project and depending on your skill level, can be done in a matter of hours. You're only out the seals (about $15), an intake manifold gasket, crossover pipe gasket, and fuel line (also a good idea to replace the return lines on the injectors at this time). Including freight, you're less than $75 for the job, including the tool to take the DV holders out.
Understandably not everyone feels up to working on the IP. If you aren't mechanically inclined or if you have a habit of breaking more than you fix, it's worth your time and cash to visit a reputable shop.
