Help -- Blue smoke @ startup
Hello,
I need some help diagnosing an issue. I have a 2009 Quest (3.5L) with 194,xxx miles on it. Regularly serviced and runs great. The engine has always used some oil but seemingly normal for the 3.5L. It leaks a few drops but not a significant amount. It has no CEL, no missing, idles fine. Just got back from a long trip to Florida over the holidays - about 1500 miles round trip, including running around miles. On the way down to FLA, it used a half a quart of oil for 600 miles. That was the most I've seen it use. Typically, its been a quart every 2000 miles in city driving. While there, I changed the oil/filter using 10w/30 synthetic as it was due a change. On the trip back it used about 1 qt for 600 miles - double the amount on the trip down. While in FLA, we noticed it starting to puff blue smoke on startup that clears up in a few seconds. The smoke at startup happens even after it has sat for 1 hour. It's definitely oil burning based on color and smell. After it clears, it does not smoke when running or accelerating as best I can tell. As a side note: Both valve covers and PCV have been changed within the year. PCV about a year ago when I changed the rear valve cover. The front valve cover replaced just before our recent trip down to to FLA. Any suggestions for a fix or what to look for? My wife loves her van and wants to keep it! |

Here's an article of oil burning (blue smoke): Blue Smoke From The Exhaust (Causes & How To Fix It)
It has causes and possible solutions but given the age of the vehicle you may be looking at some engine work. Good luck. |
