Is there a vehicle inspection in Alaska? Reason I'm asking is because I'm looking at diesel engines to swap into my truck. I know some states, don't inspect diesels, others do. Most states won't let you swap in an older engine. Some states will let you swap in an older engine as long as it was offered, etc, etc. Just wanting to get some info on the subject. I'm good here in Oklahoma, but if I move up there for my next assignment, I don't want to be screwed.
