First of all with my first post here, I'd like to say thank you to all who contribute here. I also want to acknowledge that there is already good information posted in these forums about what to think and/or do about a leaking bent tensioner and leaking timing cover gasket. I had a Mazda dealership recently perform an oil change on my 2015 Mazda CX-5 GT and mid-service they provided a video and recommendation for replacing the drive belt tensioner for $451.00 and also timing cover gasket for $911.80. I attached a slightly edited version of the video I received. I edited the continuous video to take out my license plate in the beginning and end. This is no doubt my vehicle. I declined the services. What do you think about the findings that are shown in the video? I'm thinking I need to do my own investigation? This is the first time I've ever experienced getting a video like this and wanted to share it here. Thank you in advance to anyone who takes a moment to chime in! 2015 Mazda CX-5 with 51k miles as of October 3rd 2020.
