Hey everyone I’m not sure if this will get read but I bought my outdoorsman in April and noticed the tick.. had hemis before and never heard that.. talked to 2 mechanics and both say it’s the infection and it’s normal.. they both said the same exact thing they’ve heard louder.. it’s not a knock.. when speed up its loud As hell.. but I take my foot off the gas truck is gone until the eco comes on... truck has 120k on it.. very clean and the history of the truck says this vehicle was well taken care of.. any would be appreciated before thinking of bringing it to a dealer.. thanks
