Tried a search but turned up nada.

My Girls 1986 190D has a fuel rail leak. She is wanting to take it to her mechanic to have it fixed. I wanted to know if this was a common problem, or easy to fix, or something I don't want to get involved in? Also what would she be looking at paying to have this fixed from her mechanic. I know this isn't too descriptive but it looks like they are leaking around the round pieces going into the fuel rail, Injectors maybe? Don't really know my way around a MB.

Her mechanic also charged her 250 for oil, and trans fluid changes. Is this normal or is he getting some extra beer money? I though it was really high, but he did use synthetics in it so I'm really not sure. He is not a big dealer, just a guy who is certified but with his own place out in the country.

First tell us something about the car (year, model, chassis maybe).

Can you identify the "round pieces" in any of the pictures below?

I believe they are part #179 in the second picture. They appear to be leaking from where they go into the top of the engine.

First of all you should dismantle the noozle holders and replace those seal rings (detailed below).

#179 is the noinjector nozzle holder combination (part no. A 002 017 22 21) and it has some seal rings #227 (part no. A 601 017 00 60) as fitted into the engine.

The parts in the nozzle holder body (#185, part no. A 002 017 17 21 or A 002 017 03 21 ) are as folowing:
#191 Spacer washer part no. A 001 017 42 52 (0,80mm) - many different sizes, going up to no. A 001 017 57 52 (1,98 mm)
#197 Pressure spring part no. A 000 017 13 17
#203 Pressure spindle pin part no. A 000 017 13 74
#209 Spacer washer part no. A 000 017 59 52
#221 Noozle needle part no. A 000 017 29 12 or A 000 017 46 12
#215 Union nut - nozzle retaining nut part no. A 000 017 31 16

(Note: parts number are given for chassis WDB201122 MB 190D 2.2 USA with engine 601.921, for particular chassis and engine, please ask me)

Sounds like it is a relatively simple job, which is what I was thinking. I do not know what chassis it is, how can I figure that out? But it is 190D 2.2, 1986 4D sedan. Is there anything else that would be good to do while I'm in there?
