Ok so last night my fiance and I were going to leave to go to the grocery store and started my truck. It'd been making a sound for some time but we figured it out to be exhaust sound. He felt the truck and aaid it was coming straight off the engine and was the valve train grinding itself , or so he thought that's what it felt like. So I called a friend and asked about her friend that sells vehicles I seriously was going to be trading my truck in like today. She gave me his information and I said I'd contact him this morning. So we went grocery shopping. Finished and went to the bank. At the atm my fiance again asked me to pop my hood. Put his hand on the a/c compressor and came back to the truck with a smile. Said it wasn't valve train and truck didn't need to be traded. Just said we would start saving for a new one.5 minutes and less than one mile later I got home. I shut the truck off and popped the hood because he was gonna show me what he was talking about
