With my new to me ‘19 bighorn, I had a few issues, even with it being a certified pre-owned. Currently, I’m getting a “putt putt” sound, if you will, at start up and while driving. Almost sounds like exhaust issue (had one already just before the muffler). This sounds like it’s at the bottom of the engine. I checked the oil since I’m getting an oil smell after driving it a little while. After the truck sat for a while, I checked the dipstick. Level is high. 1/4”-1/2” above the top dot. Dealer did oil change last. I read a lot through this thread about overfilling won’t usually hurt the motor, but would it cause cavitation? Could that be the sound? (Can’t figure out how to upload the video I took for the sound)
