    M104 engine - fully synthetic oil?

    I've just had my 1994 E320 serviced at the MD, and on double checking my bill, they have charged £113.31 for 7 litres of "Mercedes" oil, which is a 5w30 fully synthetic oil, and makes Mobil look cheap. I've phoned them up to query the price, but more importantly, the usage of fully synthetic...

    W124 M104 1994 air pump

    Having recently fully restored my e320 coupe I have decided to replace the viscous fan, clean out the rads, renew compressor and dryer etc...The bolt holding the fan on was a nightmare taking 3 hours to release only after cutting out the coupling. Having checked the other pulleys and idlers I...

    m104 vs 230 kompressor

    Well I am thinking of a c class and my engines are the m104 2.8 or a 230 kompressor. I am wondering about economy as the car will never see a city so country roads and some motorway usage. Is there a big reliability issue with either engines and has anyone used LPG on these motors.

    m104 plea for help - belt tensioning

    All I have a 129 that has been partly in bits for around three years. As my health improves I am starting to get stuck back into it. It's a 300 SL-24 with the m104.981 engine (which I suppose is a hybrid of m103 and m104 - having the twin cams but with good old fashioned plug leads and a...

    Impulse bought a tired old W124 320TE... what to do!?

    Well I impulse bought a rather tired looking 320TE last week. Some of you may have spotted it on eBay. This is the first Mercedes i've owned – but I have done many long road trips in a variety of early 90's MBs! It's done 242,000 miles, has rust in the usual spots, has basically no history...

    W124 M104 bogging when warm + fuel leak

    My 300TE-24 wants more money :-( There are a couple of symptoms: A smell of petrol inside the car. I lifted the bonnet tonight when I got home and there was a fuel leak under the air cleaner on something that joins the inlet manifold forward of it. When it's being driven in traffic, if...

    M104 Cold Start Valve always on?

    I've been trying to resolve high fuel consumption on my 300CE-24 and after many dead ends have discovered that the cold start valve is powered all the time (12-14V between terminals). There doesn't seem to be a thermo time switch on my model and I've monitored the CSV as the car warms up from...

    w140 s320 m104, uneven idle

    Hi everyone, Just wanted to pick your brains on this one..I purchased a w140 s320 limo business edition in august. Great car, which I purchased from a relative. As the owner has passed away, the car was parked up for about 9 months. When I got the car the engine was running rich, black...

    M104 - more oil leaks

    The S124 passed another MoT last week, which I'm pleased about, but more oil leak advisories this year! I seem to be chasing oil leaks round this engine. Having fixed the cam cover, timing cover and oil level sensor leaks I now have one from somewhere near the oil filter. I guess it's...

    m104 more power options

    Hi looking for the best way to get 350-400hp from my 300-24vTE, is turbo the only sensible way? A supercharger is easier.....with a standalone ecu can i ring much more out of it....Any thoughts?

    Fitting a throttle cable W124 M104

    Hi all, this is my first post, so apologies for noobness! I've been reading a lot of threads on sticking throttles, heavy actuations etc. and other stuff related to accelerator issues. I started looking at mine since I was having similar problems, its very stiff, and abrupt most of the time...

    Quicker steering box to W114 powered by M104 3,2

    I was on the race track yesterday with my Coupe to make a base test of what's working and what needs to be improved. Car is really fast with rebuilt suspension and brakes but the steering could be quicker. Is there a quicker steering box from some other model to be fitted in W114? Thinking of...

    M104 E320 engine in a W114 Coupe. Pictures

    Hi all, during the past 1,5 years I'm been working on this swap. The car has been test driven now and appears to work fine. Very fast. Some fine tuning to be done though, eg. throttle actuator: after constant revs on load and pushing the clutch pedal (traffic lights etc.) the engine has a...

    M104 HFM hesitates cold when revving up. Open air filter.

    The engine starts fine with smooth idle. When touching the gas pedal it does not respond. When warmed up everything works fine. Can an open air filter disturb the HFM-system? I needed to make the change due to lack of space for the original in my swap to W114 Coupe. /johannes

    RPM signal to tachometer in M104 E320. Where does it originate?

    In my W114 swap I cannot get the tacho working. Any ideas where i can tap the rpm signal since the "normal" green/yellow is not working. See pic. Engine is -93, 5 speed manual and non-ASR. Thanks. /johannes

    M104 HFM cruise control. Any problems if disconnected?

    I have swapped a M104 from E320 into a W114 Coupe. It was originally a non-ASR car and 5 speed manual. Now I'm facing some problems with the engine not revving (max 1500rpm i guess) and having high idle. When idling it runs very smooth. Can this symptom be due to a disengaged cruise control? I...
