Is your older Honda Accord burning oil like crazy? My 2009 Accord EX-L was. At around 96,000 miles, I noticed that its 2.4L i-VTEC engine was eating a quart of oil every week. I checked to see if my car had a leak underneath, but it didn’t. I feared for the worst, as excessive oil consumption is no small issue. After researching online, it seemed like my car might have bad piston rings. This would explain the oil consumption issue, so I figured that was probably the problem. However, some sources suggested replacing the PCV valve and trying some cleaning solutions first. So, I got to work. Let's start with the valve. I’m not a mechanic, so I’d never heard of a PCV valve before. Regardless, I watched some tutorials and got to work. All I needed for the swap was a pair of pliers and a 17mm socket. I found the valve above the alternator, which was a relief as it meant I did not have to take anything apart. I had managed to find a new valve for about $15 at my local auto parts store.
