IN the jetski racing world they would paint your engine. That would signify that the engine was legal. If the paint was off of your engine you had to get it reteched. Same idea with the turbo. Season starts there is a turbo teching party. Compressor housings are pulled, go/no go gages are used. A lead crimp is put around the turbo once is has been teched and to hinder removal of the compressor.
