Q. My 2011 Toyota Venza has a small oil leak. My local repair shop, which does great work, looked at it, saw oil, but couldn’t pinpoint where the leak was coming from. At this point, they suggested I just wait and check the oil a bit more often. Any thoughts on how I can find the leak?

A. The best method to find an oil leak is to add a special dye to the oil. After the car runs a bit, check for leaks with an ultraviolet light. In this case, you might want to return to the dealer or have your mechanic take the car to the local Toyota dealer. Some Toyota models with the 3.5 liter V-6 engine have had a problem with a leaking oil cooler pipe. Although this is not a recall, Toyota has extended the warranty on this specific part for up to 10 years and 150,000 miles in some cases.
