Yes I'm well aware of the regulations pertaining to replacement, non compliment engines. But, scrap yards also typically allow people to buy things out of the yard they find and want to take home. There's no documentation other then a scrap metal receipt. The scrap yard is under no regulations of how they dispose of scrap once it's been surrendered to them. Again, I would endorse anyone doing such, but it's totally possible to do and be within the regulations set forth for "destruction and disposal".truth
but the other side of the regulation is that the facility that is in charge of replacing/disabling the original engine is also required to document it's disposal. So once it hits the scrap bin, it has to stay there and then they have to keep up with the documentation of where the scrap went to.
they ain't playing
