Turbo Protection all the way!
At the moment of engine shutdown, the TURBOPROTECT check valve closes, directing oil under pressure, to the turbocharger, carrying away built up heat and providing lubrication until the rotating assembly comes to rest. This lubrication continues for 2-3 minutes which further cools the turbo.
With oil being directed under pressure into the bearing housing, the bearings remain centered with the required cushion of oil, thus preventing turbo damage.
At cold start-up, the turbo gets oil immediately because the oil is already in the feed line from the TURBOPROTECT.
