Wooooowee, that hits my sweet spot ;) Sadly not a diesel though.. and nowhere near the condition :(

I saw this and thought of you Jeremy. Took a big leap to take a fairly stock car and cobble in a Mercedes Diesel.
-
Honestly, the best thing that could have happened to it. I am a ford guy (obviously).. but they don't have a diesel as good as the OM617!
-
Those are great little engines, I'm surprised you don't see more MB diesel transplants, at least where speed isn't the deciding factor.
-
At least where speed isn't the deciding factor.
But they can easily do 300-375 ft.lbs which is comparable to a fairly modified V8, so I'd think itd do alright with moving the light Mercury around.

Hmmm good point. Just another candidate I can add to the board for if I do my dream swap of a diesel engine into a VW bus/van. A nice turbo I5, be it VA, Audi, or MB, would be great for pushing all of that boxyness. They did it with the W123, and it's heavier!
OM617 + anything. Has anyone put these in a boat?

its a SHAME that more companies didnt use OM617 engines..

Here is My Mercedes with its 617.952.

The valve cover is off to do a valve adjustment.
It is a real moose compared to the 1.6TD.
-
I shoulda bought the Wagon I was looking at :(
-
These are definitely old school diesels. You roll up with the window down and they have that same clattery diesel sound. I can't hear the turbo though.
-
I wish our engines were set up like these, a set screw for valve adjustments instead of shims.
-
Yeah, there's a lot to like about the OM616 and OM617 engines. Easy valve adjustments. No worries timing chain and cast iron head. Mercedes chassis, as solid as they are, though, are a order of magnitude harder and more expensive to rebuild than the strut-based VW designs.
-
Hi,
An order of magnitude is that to your mind twice, squared or maybe 10x as high?
I have not seen anything to support this.
It does have a drive shaft and a differential which are parts built into the vw transmission. It is pre-electronic for the most part. It uses a vacuum pump that does most of the functions that electronics do including shifting the transmission running the door locks and heater controls.
I have done some maintenance to mine every part was relatively inexpensive. For instance changing the cable to the hood was 10 dollars for the cable assembly and 4 dollars more for a new lever as mine broke. It takes 8 quarts of oil guess that is more. I put a new 6 dollar gasket on the cam cover when I adjusted the valves.
The fuel injectors and glow plugs are pretty much identical price points to the VW IDI.
-
The vacuum leaks are horrible on the Mercs, maybe more so on the gassers. I maintained an 82 300D for about 6 months and it seemed most everything I bought for it was "just a bit more" than VW. I never had anything less expensive than VW, but look at it realistically...VW were cheap economy cars and a Mercedes is a Mercedes.

Your comment about vacuum leaks is a bit strong. I have not had any vacuum leaks in my mercedes. Yours was was leaking. Both of our cars are small sample sizes to make a broad condemnation of the breed. I would rather have a vacuum leak than need a new computer or computer sensor. Replacing a plastic or rubber line is very easy and cheap.
As the cars were required to meet more standards the company made more circuits to keep them legal. At some point it became more economical to replace the vacuum circuits with electronic circuits. Unfortunately many of the older electronic circuits are now failing due to capacitors drying out, much like having rubber and plastic tubing fail.
My 85 was the last year that they imported it. They had an EGR with vacuum control circuit. An ARV with vacuum control circuit. There are some pressure lines on the intake manifold which like vacuum lines can leak They help to control the fuel delivery but are not essential and can be removed except the one to the turbo. Mine is not, but I have heard that the 1985 california car had big bag on the exhaust to help with emissions. It required a different transmission as it in the same space as the starter motor. Apparently the transmission that they chose was less robust than the one used in the other cars.
These cars are unique amongst auto transmission cars. They can be tow started if the battery is dead.
Still they don't have much in the way of computers, even the oil pressure gauge is strictly mechanical. No catalyst, no OBD2 port.
The engine is just your basic IDI type of diesel. It is well built and with normal service should be good for 3-500,000 miles. Most of the worn engines that I have heard about needing rebuilt have been run on wVo and have gummed up rings.

Yea the vacuum leaks on my 84 mb 240d were ongoing.
Although it was solid like a rock - no clunks, no tinny slamming car noises - just a bit slow to speed up.

No comment about 80's benz products and there propensity for developing vacuum leaks is too strong. Vacuum powered window regulators wtf? Those cars have a mile of 30 year old brittle vacuum hose running around. That said they'll run forever with or without operational vacuum dependent equipment!
-
The door locks are pretty unique. No extra buttons Just the four door locks, when you push down the drivers lock, the others are obedient and slavishly follow.
