    Mercedes driveline rumble

    I've had the car for almost a year and have been trying to get rid of various vibrations as much as i can had no luck solving this rumble issue. I have other unrelated vibration issues (engine vibrations due to poor quality motor mounts and a bad rear muffler). It's more a feeling than a bad...

    Phobia of working under a car on jack stands

    Well, today's repair didn't go as planned. It didn't go at all in fact. Was about to replace rear flex disc and driveshaft carrier bearing/bushing. The fact i had to have 2 wheels (or one but without having the parking brake engaged anyway) up the air made me too uncomfortable to crawl under the...

    Mercedes: motor mounts bad out of the box?

    As the title says, one of the first things i did when i got my car last summer was to replace the completely collapsed motor mounts with new ones. I used Lemförder ones as they're supposed to be MB's supplier or at least be on par with what the dealer sells. I was happy for a few weeks, thought...

    Too much antifreeze to water?

    My car's cooling system is supposed to hold 7.5L. When i got the car i bought a 5L jug of concentrate and drained and refilled the system with a 50/50 mix. Two months ago i had to replace the water pump and refilled with the previously drained coolant and had to top the level up and can't...

    Cylinder bore damage

    Car is a 2000 Citroën Xsara 1.6 16v that belongs to a relative. TU5JP4 engine, less than 100,000 km. The story is that it started smoking heavily on start up and go through a ton of coolant. The oil was a milkshake but it wasn't that bad. Removed the plugs to see what was lurking in there. 3...

    Diesel fuel filter replacement interval

    For guys and gals driving a diesel car/truck or using any diesel equipment, how often do you replace your fuel filter and based on what? All diesel powered things have a recommended filter replacement interval, i guess it's something like every other oil change for my car. I remember replacing...

    Is a high mileage 07 Volvo S60 a good buy?

    I like my old worn 96 C-class manual but i'm looking for something more modern with less age related issues, automatic, with a good sound system and good seats. Preferably a diesel too. I drive a lot for work and don't have time much time to spend on replacing parts. My first choice is a 04 to...

    Part throttle vibration at highway speed

    Well, my car is developing a second issue. Now i can hear (more than feel) a subtle low pitched vibration in the cabin at highway speed and it is absent when coasting but seems more pronounced when i don't apply full throttle. Had a local shop replace the front flex disc and motor mounts...

    '97 Mercedes rear wheel noise when decelerating

    An annoying noise is developing at a rear wheel. It's a chirping noise that happens while decelerating at low speeds and matches the rotation speed of the wheel. It is more pronounced around 35km/h and lower. At first i thought that it was happening while braking but just decelerating seems to...

    Driving without a fan

    Had to replace belt, tensioner and pulley. Of course i had to remove the clutch/fan as well as the shroud which was already damaged and just broke in half when i took it off. I decided to drive the car without the fan and shroud and deal with this issue later. Got lazy and never looked for a...

    Manual transmission weird shifting technique

    I've been driving many cars with tired synchro rings over the years and i quite enjoy how smoother the shifts are when double clutching some of them. With some transmissions it is also possible to float gears but most automotive synchronized transmission really don't like that punishment. I have...

    Oil for an old Mercedes manual tranny

    Hi everyone. Couldn't help it, bought another old diesel Benz recently. The car is a 1997 C250 Turbodiesel that has done 370k km. Shifting from 2nd to 3rd is quite notchy and makes the bad flex disc clunk quite hard (still have to replace that). I think i have a worn 3rd synchro ring since all...

    Best oil for cleaning and stopping blow-by

    Hi everyone, recently bought another MB diesel, a 97 W202 C250 Turbodiesel this time, with the OM605 turbocharged engine. It has 370k km (about 230k miles). It has quite a bit of blow-by, the cap isn't really dancing but it looks and sounds like it would fill up a plastic bag in no time. I...

    New quirky car

    My girlfriend bought this car, and i thought it might be interesting to some of you since this isn't a car model you see every day on bitog. This is a 2005 Peugeot 407 2.0 16v 5 speed manual, It has the highest trim level (Executive pack) . This car is so vastly different from what i am used...

    Car sitting for 3 months

    Hi everyone. Unfortunately, my car has been sitting for about two and a half month as im waiting for my new wiring harness. When i parked it outside, the tank was about half full, normal tire pressure. Two weeks ago i decided to completely fill the tank up (our gas is E10) and added a dose of...

    Confused about coolant

    My old E250 with 500k km on the clock has been filled with the universal green coolant at some point. I'd like to flush it and use the proper blue coolant i always use, G48, the one that replaced G05 at some point. (MB 325.0, 326.0 if pre mixed) I've been told to use some pink coolant that also...

    Mercedes owners: best riding E class

    I currently own my 2nd W124 and it's my favorite chassis and always will be but my only grip with the car is the ride. It's perfect over good road suface and at high speed, good over speed bumps but rough when the surface gets crappy with a lot of small imprefections (terrible on the patched...

    Harsh ride. Struts?

    Something i notice with my 93 W124 is that it doesn't ride like it should. Low speed driving is ok, highway speeds are ok but the ride is harsh between let's say 50 and 100 kmh. The weird part is that it seems almost worse when the road is nice. The asphalt on half on the roads in my area is...

    Maximum MPG out of a diesel

    For obvious reasons, fuel economy is more important than ever. I am hypermiling as much as i can but have only owned gas cars for the past few years. Now i'm trying to squeeze every km i can out of each tank in this thing: https://bobistheoilguy.com/forums/threads/my-new-horrible-beater.361149/...

    Beta ratio

    Oil filters are rated between 20 and 30 µm if i'm not mistaken and it seems that diesel fuel filters are rated between 8 and 10 µm but what beta ratio to expect for a given micron rating? I'm pretty sure it's not absolute, only nominal but what kind of efficiency to expect from the filters used...
