The all-new Crank Seal Guard is an inexpensive insurance policy to protect your very expensive BMW engine from potential catastrophic engine failure. It is a high quality cover made from a single billet 7075 Aviation Aluminum Alloy.
The accessory belt sits under some common leak areas in your car's oil and coolant system. If you experience one of these leaks, what can happen is your accessory belt can start to walk off your crank pulley. Because of the design of the engine, tiny shards of rubber from your fraying belt can easily find their way through your crank seal. If this happens, these little pieces of the belt can get picked up by your timing chain and find their way into your valve cover and cause damage by blocking your oil pickup, starving your engine of oil.
Additionally, we've even seen cases where the belts snap, wrap themselves around your crank pulley and force the entire belt into the engine, through the crank seal! If either of these situations is to occur, you'll be certainly looking at a costly new engine, which will cost tens of thousands of rands.
Crank Seal Guard is a precisely engineered piece of art, which acts to block belts and belt particles from making their way through the crank seal, by reducing the gap between the Crank Seal Guard and the crank hub to arround 0.5mm, saving your engine!
