►Engine oil is critical to engine health when it's in the areas it's supposed to be in. However, excessive oil in the intake tract, thanks to a failing PCV, can cause a smokey exhaust, foul spark plugs, and other harmful situations. Luckily, replacing the PCV on an M272 engine or M273 engine is a straightforward process that anyone can perform with this video's help.
PCV failures are a common problem for all sorts of European engines. The PCV is designed to release the excess pressure within the engine but keep the misty oil particles inside. When the PCV fails, the engine will pull that oil vapor into the intake, causing oil build-up.
Watch along as Danny Kruger, FCP Euro's Mercedes Expert, replaces the PCV on his W203 Mercedes C350.

Nobody ever talk about how much better it performs

Great DIY video and thank you 👍 I have an A 207 (2010 E350 Coupe) so there were some slight differences but overall very helpful. Especially navigating the Driver's side breather! I ended up using a Leatherman tool with a 1/4 option on it and a small Crescent Wrench with electrical tape holding a T30 bit to get the passenger side done 🤣 I had ordered the total breather replacement kit and found a few extra "caps" in it. I watched the other FCP video on MB breathers and found out where those went. I definitely understand how different models have different variations and your 2 videos certainly helped. Also, the passenger side breather used an E8 instead of an E10 (this is why you buy an entire set of sockets/etc instead of just 1!) and your replacement kit also came with an E8 as a replacement so you guys and gals are on the ball when it comes to replacement parts. Well done and thank you again for the DIYs and replacement parts!

Nice work!! Thank you for wrenching with us!

11:30, What exactly is that part's function vs the crankcase breather that you changed on the back passenger side? I have experience a lot of oil loss for some time now, even when changing the breather on the back passenger side (that old part had seen better days!), but I am still losing a lot of oil with no visible leak. Should I change the part at 11:30 too? I have seen pictures of the inside of that part and it doesn't look anything advanced, it's just plastic on the inside. How can it fail?

Perhaps you will speak about it in the video, and I apologize if you do, but if you do indeed get oil into the intake manifold, you change this part assembly out (as you've instructed in video), but what happens to the buildup of oil in intake? Are there additional measures to take if that is suspected?

@phillipbagshaw340 Ай бұрын

This might be about 2 months too late, but I would personally recommend taking the intake manifold out of the car and cleaning it and doing the repair kit on it as preventative maintenance as they are a very common failure. If you notice oil in the intake, then the intake could be already compromised and it's just a matter of time before it breaks, which leads to poor performance and rough running.
