Oil Leak Triggers Check Engine Light
Brian England, Mon, Dec 18, 2017
Recently, one of our customers came in with a “check engine light” on. When a “check engine light” comes on, many drivers think it’s due to an electronic issue, but sometimes it can be a mechanical issue.
To get an idea of what was causing this particular problem, one of our service advisers, Brady, performed a courtesy scan for codes and saw that a few trouble codes came up. As a result, he set up a job ticket and gave the customer an idea of the possible diagnostic pathway as well as the cost for the time to perform the diagnosis.
Once the diagnostic estimate was approved by the customer, the technician did a more comprehensive computer scan and evaluated the codes and related data. This led him to a close examination of the engine, and this led to finding an oil leak in an obscure location. It turned out that the valve cover seal was the issue!
The valve cover seal was replaced, the system was reset, and the car tested by the technician. Then after the final quality check by the office, we called the customer to let them know that all was okay, and it was fine to pick up the vehicle.
At that point, the customer still had to drive the car for a couple of weeks to allow the car to reset all the drive cycle monitors before we could say it’s absolutely fixed, especially when there were numerous codes in the system.
Of course, this is just one of many issues that can trigger the check engine warning light. A couple of years ago, we wrote a blog post where the problem turned out to be a blocked exhaust gas ﬂow in the intake manifold.
So, if your check engine light comes on, you definitely want to get it checked out. And, just as we did for this customer, we’ll do a free courtesy scan!
