Hey Scotty, I saw your video about Scion XB's a few months ago (a reliable every day driver that could last a long time and could be purchased at a good price) and you where correct. I have the 2009 XB, and with just a little TLC, it runs great and doesn't consume any oil with 150K on it. My question is, when I purchased it, it did consume about a quart of oil every 2500 miles, after doing the basic MAF sensor cleaning, changing filters, and plugs, it was still using a bit of oil. Once I changed the PCV valve, it completely went away and no longer consumes oil. I did see the PCV valve was gunked up when I removed the old one, how does that affect oil consumption? Do all of these 2.4 4-liter engines from this period eventually consume oil or just the majority of them? What should I expect over time?
