What ones you don't have to unbolt the uppipe so that one should be out of the ? any others also I was looking under my car today and I could not see the oil line that goes into the bottom (the one people have a hard time getting lined back up) am I blind or just missin it??

PS. How much coolant is lost during the install? and how in the heck do I find the 5th bolt on the driver side injector bracket I have found the obvious 4 but the 5th one is a stumper??
