Thanks for the responses! I'll forward these suggestions to her. I've told her it might be a good idea to have a cylinder leak down / compression test as well as a general inspection by the dealer just to get a good baseline. Hopefully, I'll get a chance to take a look at the shield and header today.

I don't think I've seen a two door rodeo. My sister's truck is a 4 door.

Thanks again for the help!
