6.9 evaluation

I posted this on the W116 and have 265 views and no comments so thought I would try over here.

What is your opinions of getting this car and what would you guys value it at? I'm just going to post the seller description for now. also how hard would it be to fix? What's the likely culprits? Body is pretty good, A couple of small rust only. has extensive history file. Car has been sitting non op for 6 years since seller got it.

BTW, I do know, own and work on my MB's, and know what I would be getting myself into in general. I've read most everything I can on these cars, but have no experience on FI cars.

Sellers description:
When we acquired the car it had been sitting for a little over a year. We proceeded to do the things that needed to be done to get it running and make it roadworthy. The fuel system was completely gone through. All parts were replaced with either used spares we had or new parts sourced directly from Mercedes-Benz. The pump and filter were replaced with new units. The fuel accumulator was tested and cleaned. All fuel lines were removed from the car and cleaned out with air and an ultrasonic cleaner. The warm up regulator was replaced with a rebuilt used part. The fuel distributor was replaced with a used one. All of the fuel injectors were removed, cleaned in the ultrasonic, tested and replaced. The fuel tank was removed, cleaned out, and reinstalled with a new fuel strainer in place. The brakes were bled but the rear brake lines are weeping and need replacing. The rear output seal on the transmission was replaced.

Although we put a lot of time and effort into this car, it is not perfect and still needs some work to be drivable. The fuel system is still not 100%, I believe the fuel tank needs to be removed and cleaned again. When I parked it, it would start and run for a few moments then die. The rear nitrogen canisters which "absorb" the bumps in the road are blown and need to be replaced. The car is still drivable but is very stiff in the back. The air conditioning needs to be charged to blow very cold.

Can you edit your post to clarify where the seller description starts and ends?

6.9 evaluation

Ok. I think I see where the description starts. I assumed the "I don't work on MB" could not possibly be something you yourself wrote.

So to boil down the seller description:

- tried to get fuel system working correctly and failed. Fuel system still isn't right. Might have even bastardized the system with incorrect parts.

- expensive 6.9 suspension system is not working and you should plan on replacing the entire system, whether with original ($$$$) or springs (huge loss in collector value).

- AC does not work.

- it has some rust (added by you).

Some questions:
- What year is the car?
- North American big ass bumpers, ugly headlights, and less power? Or Euro?
- will it need paint too?

This car sounds like a mess from the description. For me (to understand my bias) a running, driving euro 6.9 has some serious appeal, but it would still have to be near free for me to buy one. I have no love for North American park bench bumper Benzes, and would avoid most cars with Chrysler climate control. So the only reason I would buy one would be to part it out, scrap metal the bumpers, and rid to world of one if the big bumper cars that I believe are the whole reason all 70s-80s benzes are so cheap in the US. Now, a 6.3 would be a whole different story, even a euro 6.9 tugs at my heart strings.

Edit: I forgot to make sure my tone doesn't sound so negative. :-)

I have been told by someone who has owned both. The 6.9 is a much finer machine than the 6.3, which is basically a hot-rodded w109.

Now I think it's worth saving.

Just learn to work on it yourself.

To me big minus, doesnt run . big pile of god know what to fix.

plus side , he's already replace a lot of suspect parts. so maybe he's messed up basic settings,

rest of car is in pretty good shape

Euro car! I'm with you I just could not own a big bumper sedan or R107.

Potential parts car also available, could use / sell parts and maybe recoup expenses some.

While I am complete newbie on FI, I would certainly first avail myself to forum help in troubleshooting. worse case I have indie that has experience on M100 engines that could offer advise and at some point do work if needed.

I found the ad. It's hard to not say, "buy them both ". Looks like potentially a great deal.

Injection would be least of your worries. K-jet is so darn simple. I haven't run into a 107 that I wasn't able to make run yet because both d-jet and k-jet are so simple. K-jet? Keep using in it so doesn't varnish up and fuel tank doesn't rust out. Might need to get another w116 fuel tank, but "big whoop".

Why don't you post it on the 6.9 forum at m-100.co. They can be very helpful.
