I am in no way an expert in mechanicals, but these are some points to discuss on how to really prolong the longevity of your W123 both 240 and 300 series. #mercedesbenz #vintagecar #w123
Drain tranny fluid from both the pan *and* the torque converter *and* change the filter (instead of the evil flush I run fresh fluid for a month before changing the filter then do a complete drain and fill with new filter). Also check and renew flex disc - driveshaft detachment at speed is undesirable.
My 300D wagon has now 1.280.000km on the clock. Has been a former taxi. It‘s leaking oil like nothing else. The transmission is still working fine. Big play in the steering box - which can be refurbished. Overall it still runs strong.
I have to point out, it‘s also my daily all year round. :) The pre-glow relais died a few weeks ago. The car was parked overnight. I thought you‘re able to crank the old Diesel simple longer and it will start somehow with noise and rattleing. We tried to heat the engine block with a torch and tried to get it started with little brake cleaner. I was told the iron block has to ,pre-heat‘ itself and the internals. There is almost no chance to get it running in winter temperatures. Second failure was not really a big issue: The alternator. I ran the 123 for 5 days after the alternator died. Which was like 5000km. :D And then the battery showed signs of dying. ;) Third: Hydraulic rubber hose to the rear axle was torn and broke due to age. I have to address the play in the stearing box. That‘s bad. :D
@@Altanox Yep, just take extra oil with you. I have to refill around 100-200ml every 1000km. It‘s definitely a poor solution. Engine and transmission have to be taken out to address the leak correctly.
I have this wagon, also an '85. a wonderful car. This video recently popped up on my youtube page due to the fact that I recently watched another one of yours videos on your R1100RS, I also own one of those, a '96 I guess great minds must think alike, keep up the good work!
it's beige ("ivory white") with a palomino exterior. The beemer had been sitting for 5 years before I got it about 5 months ago, I changed all the fluids and filters, new brake pads, new cables, new battery, new fuel filter, new fuel pump, new fuel lines, new fuel injectors so now it runs good and is reliable for now. It needs new tires, I want to put on Pirelli Angel GT's but they're backordered. Also the fuel gauge isn't working. The maintenance list for the wagon you came up with is great. I've done most of that already, I have new monark injectors but still need to replace them. I have a new cohline upper oil cooler hose but you can't find a decent manufacturer for the lower line anywhere. Will be doing the engine mounts at the same time. When replacing the glow plugs it's also a good idea to ream them out, mercedes source has a good tool for this. I didn't see the coolant you recommend in the comments... @@SirDrifto
I just bought a 1981 240d because of your videos. Found it here in LA for $300, in great condition. Silver, with navy blue interior. The interior is super clean, but the paint was faded. I buffed it, and happy with the shine, but the fade is there. I’ll be taking this on my move from LA to Seattle, so I’ve been doing a lot of work on it.
I got lucky. It was in the city of Duarte just sitting on the driveway for 4 years. The owner passed away with Covid. The silver paint is faded, but I did my best buffing it out. I wanna get a paint job, but haven’t even looked at prices.
@sirdrifto I freaking love it! I just wanna make sure it’s roadtrip ready, and I’m also working on the ac. I have to convert it from an r12- r134. I just changed the support bearing because it was broken, and also changed out the flex discs, radiator, and water pump. The speedometer is broke, so I bought one off eBay. Scared to work on the Speedo myself though lol
Good points made in the video on what items to keep on top of, the only other critical ones would be the timing chain and vacuum pump. The turbodiesels are a bit harder on their timing chains than the non turbo/240's and you really want to be inspecting the chain stretch (and likely replacing) the chain every ~200k miles tops in most cases. With frequent oil changes/good oil this can often be extended based on results of checking the chain stretch. The vacuum pump on the front of the motor should also not really be trusted much over 300-350k miles as they are known to fail from fatigue and can dump parts into an otherwise good engine, destroying it.
My 17 year old daughter and I are road tripping our 1983 300sd all over the country this summer, be interesting to see how it holds up lol thanks for all the great videos
Excellent video! For your information, the slowest model is the 200D, though it came in 2 versions, 1976-1979 and 1979-1985, the former having only 55 CV while the second one (the one that I own) had 60 CV. Even these cars are drivable in modern traffic, I use mine in the highway with no major issues, though you want to use a long speeding lane to incorporate.
Hello Michael, how have you been? You're absolutely right 👍 When I did live in the US, I had a W123 300TD (sedan) very well maintained, when I bought it from the first owner (an older gentleman) it had over 425,000 mi., When I had to sadly sell it, it had over 510,000 mi. running tip top, beautiful car! I'm now the proud owner on an S123 (a wagon like yours, or an Estate as our friends in the UK refer to the S123 :) ) But my S123 is a 230E Euro specs and of course gasoline operated. Maintenance is key 🗝️ to a healthy and happy 123 MB 🤗
Glad to hear someone who actually knows what there talking about with vintage Mercedes , most people never think of the oil cooler lines . I’m a vintage Mercedes intern learning under a 55+ year Mercedes mechanic planning on taking over the shop . Where in FOCO if you ever need anything, come and visit if you like (shoot me a message if you’d like to come up). I daily a 79 240D 190k and have a 1958 220s sunroof Sedan in restoration .
That fog light setup is THE BOMB!! What brand are they, can you expand a little about the setup, and is it possible to speak a little about the installation of them? Thank you very much! By the way, LOVE your film about your most excellent airhead. What a fantastic bike!!
Love the channel, Sir Drifto. I live local in Denver and own a 2019 6-speed VW alltrack which I believe might be one of the last manual transmission sport wagons sold in the U.S. Don't get the hate for station wagons in this country...love them!
Wonderful Machine! I own one as same, in beige color... I was looking for your headlamps and are so good! Im looking for them nowadays... My model has it round headlamps, thanks, Very good video
There's an actual Bosch injector tester that makes sure they are all in spec. For them to create the machine especially for this purpose tells you how important it is.
My 1983 300D has low miles speedo died at 676,000 miles. That was a few years back. I also have a1978 300SD the 254 one made. it motor is 154 one made. The 300SD has 733,000. The SD is parked because the tranny died at that milage. A few years back. To get lots of miles. Use a very good grade of oil. Change oil at 2500 miles. Keep valves adjusted also. They can go for ever. Use the 300D as a farm beater. I also have a 1980 L1116 Benz truck. Other diesel Benz I have is a 1979 240D. Found a very nice 1970 220D a few years back. The person before me did not check the oil. She ran it low on oil did the rod bearing in. She did not read the hand that states this car will use oil.
@@aj_nichols I mean youre not wrong 😄, I do like the W126, as its luxury and plush atributes are quite nice, however there is something about a W123 that has stood the test of time for me, it feels more robust. But thats just opinion.
I remember as a kid, my neighbor (in Europe) always drove sedan 240D. Passed away 20 years ago, so his son was driving it afterwards. 12-13 years ago, he sold it as I was about to move in USA.... 2 years ago I saw it last time I visited, I recognized the car in it's perfect dark green color. Asked the new owner and he told me it has 800k miles on original engine and NEVER drives it on interstate, never above 3k rpm, city driving only and never above 55pmh. My point: everyone expects to drive a car here in States 70mph on daily basis and then blames the car. Its an old diesel, even 300 wont last if you don't baby it.
@@Altanox Idk if you're right or wrong, what I do know is that car had 800k miles two years ago and he didn't even come close your level of detail when it comes to maintenance (he is too cheap) so he has to be doing something right.
I have to say mileage is a great evidence haha These cars kinda live off of oil, i'm sure he is doing regular oil changes! For the rest, maybe it's not such a big deal indeed @@YouKnowImRight2
Yo your videos are great - I have a suggestion - you don't get to the point till 5 min in. Also a little redundant. Awesome points tho! Thanks for the great video. Beautiful wagon!
