Toyota told us to send you a document to show that our engine was put in by the dealer. It was shown the work they did on the engine you received, before they realized it had more than blown the head gasket, included the muffler receipt too. The engine runs great! My truck always felt "heavy" like it was towing a load before. Now I barely have to touch the gas to get rolling. The Toyota mechanics were all drooling over this engine and were super impressed that the gaskets were included.
