►If you’re finding oil spots underneath your Mercedes-Benz, don’t panic—it’s probably not from your valve covers or oil pan. It’s most likely your oil cooler gasket that is extremely easy to replace.
The M272/M273 engine is unique in the fact that it doesn’t really suffer from valve cover leaks like a lot of other engines. Instead, what can appear to be a valve cover leak or even an upper oil pan leak, is usually the oil cooler gasket. You will typically find these leaks toward the left-hand side of the car/engine.
One way to check for the leak is to look for dirt on the oil filter seam. From there, oil trickles down toward the driver’s side of the car. If you let the leak progress even further, you will start to notice dirt and oil on the serpentine belt tensioner.

a torque wrench would be useful for this work
Did this several months back on my 07 W219. Didn't pull the power steering reservoir or remove the fan assembly. Had to replace the VVT magnet so I resealed the oil cooler adapter and oil cooler to adapter housing to prevent any leaks. Used FPC Euro for all my parts.
A large part of why I finally switched from Acura to Mercedes is because of fcp. Had tons of homework to do, & you guys consistently had exact info available that I needed (also on e90/e92's). Just noticed this leak on my c207 & feel good about getting into it this weekend. I can't rebuild an Acura transmission, or rebuild a $2,000 vsa modulator but I can handle some fluid drains & gasket replacements. Also, looks like I only need to remove my belt & hose connecting thermostat to radiator. Cam sensor (I believe) is more obstructing than my power steering res. M272.988 3.5L. Thank you!! Respect!!
Good video ,,,just to let you know ,,this job can be done without removing the power steering reservoir and the coolant reservoir , which saves a lot of time and trouble. Simply use a small diameter wobble extension with a T30 socket bit.. you need to remove the p/steering reservoir cap to get clearance to access to one bolt. Use a magnet to pull the bolt out ,,,and use gum or blue tac to hold the bolt when replacing it.
Although it is good to see how to remove the other things as well.
I did this job last weekend and I replaced the gasket at the crank case. Now I’m seeking a small amount of oil in the coolant reservoir. Does that mean the gaskets didn’t seal or is it that some oil got into the ports when it was opened?
You can be a good teacher, you explain so good really pleasure to see how you work.
Guys, do some OM648 and OM642 vids, diesel heads want tips and tutorials too!
When can we get some e63 work
Just had this same problem! Wish i had this great video at the time when i was fixing it. for me i did not have to remove the steering fluid housing, i was able to still get to all the bolts!
Excellent info! When the gasket is really bad, it will leak oil into the expansion tank as well. Then some shop tell you it's a blown head gasket.
Love the M272 content!! Bring in as much as possible!
Great job! I'm replacing the thermostat and belt tensioner and pulleys on my E550 M273 this weekend. You saved me a ton of time by recommending removing the auxillary fan assembly. Not much room with V8. Love the W211 content lately. FCP is a great resource for the DIY wrench. Thanks Again.
how did you know it needed replacing….visible leak or does it throw a code?
