Re: [MBZ] which six
So if I was wanting to go fast on the autobahn then yes the M104 would be better but if I was gonna have a motor that I have to maintain and fix myself then I would choose a 103, also whilst the 104 has more power it does not have that much more torque than the 103. My '89 2.6 M103 with 158hp (or thereabouts) had a distributor, points, CIS, and an exposed ignition system. My '95 2.8 M104 with 194hp had Motronic and therefore no points or distributor and the ignition wiring was protected from moisture and it had electric injectors. The plugs lasted longer but changing them was more difficult. It also had a MAF which was replaced once under warranty. It's hard to imagine that any of the M104's infamous headgasket and front cover leaks would not have been repaired long ago. Mine were fixed in the first year I had the C280 and did not show up again. M104 wins. RLE ** Start the year off right.

Re: [MBZ] which six
So if one of the motronic computers goes south it'll be cheap to replace? Did the wiring harne$$ go bad on you or the next owner. I think just about everyone on this list would prefer the maintenance/repair cost of a CIS/E M103 over the motronic M104. A lot of indies are capable of fixing a KE but some just don't have the equipment to handle the motronic, this limit's your repair options. Also I do not believe that your 89 had points, from memory MB did away with points in the 70's and what do you mean by exposed ignition, in good shape the KE ignition system can withstand a lot of wetness perhaps not as much as the motronic but if the wiring loom is crumbling in the motronic you are gonna be in trouble with moisture. Also what is different about the spark plug boot on the motronic? This is one area where just about every petrol powered car has an achilles heel in regards to moisture. I know some have a cover built into the boot that shuts off the hole where the spark plug sits, the M110 should have had that. Nobody is disputing that the 104 has more power but the torque figures are not quite as impressive and that's the thing about the 24 valve motor, it really only craps on the 12v motor at higher revs and in everyday driving you don't really get in the powerband. Sure if you are a bit of a leadfoot then the 24v motor is better but as an everyday workhorse the 103 wins in my opinion. What about fuel consumption between the 2.6 and 2.8, given that the 2.8 has electronic fuel injection it should have been a bit better on the juice.

The 3.0 Liter Inline 6 cylinder M103 engine (much more reliable than the M104) ... Absolute nonsense. The M104 is better in many ways. RLE ** Start the year off right.

Re: [MBZ] Which six?
Obviously yes, it takes all the stuff learnt from the 103 and goes up to the next step but it's drawback is it complexity. Apart from some of the early ones (3 litre ones) it uses motronic fuel injection/ignition (2.8 and 3.2 litre) and has 24 valves. Whilst motronic is more efficient, if there is a problem you'll need a tow. M103 uses KE jetronic and unless your fuel pump dies will keep going unless there is an ignition problem but even those are easier to fix. So it is fair to say that the 103 is a potentially more reliable motor but the 104 is more efficient. However from my point of view reliability is more important than efficiency, fuel usage for the M103 is round about 12-13L/100ks in town (about 8 cruising at 110kmh) the 104 in 2.8 displacement does a bit better around town but not that much better on the open road. I think the 3.2 litre 104 is about the same as the 3 litre 103. Here is a discussion on this topic http://www.benzworld.org/forums/w124-e-ce-d-td-class/1189311-m103-vs-m104.html More info http://www.continentalimports.com/ser_ic100345.html So if I was wanting to go fast on the autobahn then yes the M104 would be better but if I was gonna have a motor that I have to maintain and fix myself then I would choose a 103, also whilst the 104 has more power it does not have that much more torque than the 103.
