No blow by whatsoever and no leaks it’s a solid truck! New tires less than 500 miles in them. It is deleted as well. I love this truck and don’t want to sell it but I need to just don’t have the money right now. It’s got the black leather platinum interior with heater and cooling seats front and rear. No major rips in the seats. I’ve never had issues with it and it’s been maintnenced regularly, going to school at Dixie tech for automotive so I’ve taken care of everything myself. There is a TPMs sensor out. The truck is in super good condition. I am the 2nd owner. Come look at the truck and test drive. Shoot me a message!
