Mike East,
If they look at it and deem it not to be warranty, then what? I am sure they will want you to pay for repairs, do they call you? Or send a letter? If they repair or replace it under warranty, do they notify you? Or does it just show up at your door?
They will find some obscure forum, without notifying you about which one, and post what they are doing to your engine on there as well as how much its going to charge you if its off warranty. If they don't hear from you, they keep your engine.
Without speaking for Mike East, most of the known world is calling them, before whatever process they have configured for folks that send in $400 engines and are never heard from again except on user forums, kicks in.
