well i put on the blower. a buddy of mine forgot to secure everything and we turn the car on with no intake pipe on.
i agree with kb58 to some extent. if he offers to help pay then thats good but dont look for money from him cause he was trying to help you. you must always over look your work and especially people work when it comes to your car.Yeah that's fair. Your buddy screwed up, but, like captain of the ship, you're responsible for checking everything over before turning the key.
