#7 of 34 Is it worth price of maintenance to keep Mercedes? by bigdog11 Feb 17, 2007 (1:09 pm)
Just had lots of maintenance done to my 2001 C-240. Has only 76,000 miles:   1. replaced front/rear engine mounts 2. replaced engine belt 3. power steering flush 4. brake fluid flush 5. coolant flush 6. replaced side seals 7. replaced air mass censor   Does this seem excessive? Because it cost a fortune & I'm wondering if I should consider getting rid of it.   I'd appreciate thoughts on this...........thx.

Replying to: bigdog11 (Feb 17, 2007 1:09 pm) replacing the mass air flow sensor (MAF) is bull. That should be cleaned every 10k for a couple of bucks. Its two screws to get to it, and you spray it down with a $10 cleaner. There is no way that should have been replaced under normal conditions.   Everything else is typical car maintenece from what I can tell. The engine belt? Are we talking timing belt (in which case, 76k is early) or an accesory belt, like for your A/C? Replies to this message: bigdog11 (Feb 18, 2007 10:01 am)

Replying to: mdunford (Feb 17, 2007 10:56 pm) Thx for your input. It was the engine belt due to cracking.   This if my 1st Benz. Prior to this car, I had a Ford & never had to do any of this stuff however, I sold it 7 yrs. I was planning to keep this car for 100,000 or plus miles.   Just seemed like a lot of items needed attention all at once.
#10 of 34 78 mb piston lube problem by uteoat Mar 21, 2007 (12:57 pm)
I'm in the middle of rebuilding a mercedes 123 diesel. There are no oil jets in this one as described in the book. Looking further I have found no oil passage in the conrods. The engine was recently rebuilt and the conrod numbers don't match up with the corresponding cylinders, so they might have been replaced. My question is how does the oil cooled piston get the lubrication it needs if there is no way for the oil to get to it? I,ve posted in other forums to try to get this question answered and am hoping there is some mechanical genius out there that can help me out with this one.   Any and all help would be greatly appreciated. Thanks, uteoat Replies to this message: pat (Mar 22, 2007 5:05 am)

#12 of 34 Towing a C-240 by woodworkertoo Aug 29, 2007 (5:56 am)

#13 of 34 2003 C240 Spark Plug replacement by nikc240 Sep 16, 2007 (2:41 pm)
I recently had the C240 at the mechanic to replace rims and align the car and he said the spark plugs need replaced. the engine runs very choppy at idle and also making a whining noise when i start it up in the morning, until the engine gets warm. how hard is it to change the spark plugs and where would i find out how to do it myself? secondly, does anyone know what the whining noise is? It never happens unless it is cold outside. thanks for the help. Replies to this message: muffman58 (Oct 16, 2007 5:02 am)

Replying to: nikc240 (Sep 16, 2007 2:41 pm) I belive the noise you hear is the electric air pump for emmissions. It will run for 5 minutes or so and then shut off. The spark plugs are pretty easy to service. Simply remove the air tube across the top of the engine, remove the top cover that sets ontop of the valve cover, by taking loose the 8 allen head bolts that go through the cover then you`ll see the coil packs. they can be removed by taking loose the 10 mm bolts and setting aside to uncover the spark plugs that are down in the head tubes.
