Abstract:

An exhaust stack cover sized to substantially conform and fit snugly, or elastically over the end and opening of the exhaust stack of a vehicle engine such that during transportation of the vehicle, wherein the engine is inoperative, a vacuum or air flow is prevented within the exhaust stack and thus the communicating turbine. Elimination of this vacuum and associated air flow prevents detrimental mechanical actuation of parts. Specifically the turbine shaft is protected, which is particularly susceptible to damage due to rotation without appropriate lubrication. The cover can be formed from a substantially heat resistant material such as neoprene which can withstand a substantial direct temperature by the exhaust stack as well as provide some elasticity in order to snugly and tightly grip the outside surface of the exhaust stack.
