If this guy did this on purpose he going to wish he never did, that original engine is 10 times what the reman will be,we had a customer do that to a mustang for engine noise,he wanted a new engine(his warranty was almost up) but there was nothing wrong with it,so he took his car to the back of our lot and put it to the floor and redlined it till there was noise, I guess this guy though that no one would see what he just did because he came back and tried to get warranty,needless to say he did not get warrnaty,what some people will do whene the warranty is almost up!
