96 E300D Leaking IP OM606

I have a fuel leak on my injector pump and a local shop quoted me $3K to fix it. I can't afford to put that kind of money in the car at this point. I'm pretty handy when it comes to working under the hood but not sure if this is a DIY project. Anybody know if there is a gasket set available for these or if there is even a chance to rebuild them yourself? I'm in the process of getting another car so I can take this one off the road and start diving into it myself. Any advice?

Thanks,
Mike

If they knew what they were doing it wouldn't be $3k.

So where is the leak exactly? There are a few common not terribly hard to fix spots.

i would first register for epc if you havent already do so. most likely thepump will have to come out which means timing the pump and recrimping the timing chain with a $200 special tool.

Oracle12345, what do you mean by 'register for epc'? Not familiar with that term.

Do a search on delivery valve seals. They are a typical leakage point.

Yeah, I'd second the DV seals. You don't have to remove the pump.

Does it look like this? Solution follows. About $15 in parts. If you need the special tool PM me or check out tool rentals. I've got a 602 and it was pretty easy. Your car will run rough for about a few hundred miles. but clears up. (Take it for a nice long drive).

Thanks for all the suggestions. I'll get it off the road in a week or so and then I can take a closer look at where the leak seems to be. Back to you then.

Do yourself a favor and waste a can of brake cleaner on and around everything connected to the IP and clean it up. Then track down the leak.

IP's usually outlast the engine and rarely require a total rebuild.......unless messed with internally.

This is an excellent DIY about the repair of the delivery valve seals. As other posters have written, the total cost of the parts to make the repair is about $20 bucks, but I would suggest that if you decided to make the repair that you follow the step by step instructions to the letter. If you are in doubt about a particular step, post the question here, and I am sure you will get the correct answer. This forum has a pool of information a mile deep!! Good luck!!

Been there, done that. Do as others wiser than me have or will suggest. If the leak is at the top of the IP, and you are going to do the delivery valves, get and replace all of the plastic fuel lines, they leak too. If they are not yet hardened, you can replace just the o-rings on the fuel line nipples. Also get some of the small braided fuel line and replace all of the sections between injectors. While at it, replace the hardened and cracked vapor lines from the hockey puck to the intake. Clean the intake and crossover, yada, yada, yada,,, Like another poster said, once you do all that, it will run like crap. Drink heavily. Wait 24 hours (for the alcohol to wear off), then let her run for couple of hours. We'll walk you through it.

As a point of reference the PO of my W210 paid $860 in Jan. 2006 at an independent MB shop in Phoenix for:
oil change
fuel filters
injector pump o-rings
all fuel hoses
