My mechanic noticed engine oil leaking from the bolt underneath the engine oil pane. He said he will try with a new bolt and if that doesnt fix the leak, he may have to replace the oil pane. It wasnt leaking a significant amount so I came home intending to go back in a couple days when I am going to get the brakes changed. YEsterday, I checked the engine oil and int was low...it was less than the first dotted sign on the dip stick. I added almost 2.5 quarts of oil. Today morning, checked the engine oil again and Itsa tad bit less than dotted sign. I am out of town and wants to take my car to my own mechanic that I trust. What are my options to have this issue fixed? ANy insights or recommendations on cost/part/? Someone said I can try to put sealant in and see if that fixes it? Is that a good idea? What potential damage this can do to the engine it self. I have 50k miles on my 2011 highlander. Thanks.
