Hi I know this is kinda an old thread, sorry I haven't been able to get any other pictures of the motor but I really appreciate the help. I'm heading home this Friday for Christmas break and will be able to get what ever you guys need to figure it out. How do you tell the difference between the 52ci and the 59ci? I had always thought I had a 52 because mine was a 97 and people usually talk about the 59's starting in 98. However I when I was looking for a repair manual I stumbled on this https://www.manualslib.com/manual/11...40.html#manual which if you go based on the serial number range would make mine a 59?
