I currently have a 95 gl.V6 5spd. I was told today that my #2 cyl. is reading low pressure..but there is a god awful rattling. They feel it has something to do with the cam walking. I was also told that with the price of fixing it..re-adjusting the chain it would run as must as a even up engine swap , about $1500 or so. Can I look into an SVT motor? What needs to change in order to do the swap? is it just the motor and computer..or is there more to it?
