Is there really a way to tell that nitrous was used on the motor if something happened to it? Can the mechanic actually prove it in anyway? Is there a residue in the oil or anything?

Thanks for any info!!!

YES

Can the mechanic actually prove it in anyway?

He can't but a lab can. See below

Yes

I was talking to the guys at Arrow (where we send the engines to for major warranty repairs) about this. Todd said they can tell by the cylinder walls and the rings!? First I have heard about that. He said they do not test the oil anymore, the just look at the pistons, rings, cylinder walls and can tell from that. He mentioned something about "ring wash" and "blow by".

What if the guy who owned it before me used NOS and I never had it on the car and I didnt know? Can they still deny the claim? And what is ring wash?

Tough to say but I suppose you are responsible for any kind of problems since you now own the car, whether you ever used the NOS or not! Denying a warranty repair is one of the toughest things a dealer can ever try to do. Ring wash is a term used by the guys at Arrow, first time I ever heard it.

From experience, yes they can still deny the claim. They are warrantying their their product will hold up under certain use, and NOS isn't part of that use. So if NOS was used, even by someone else, then they can legitimately deny coverage.
