Due to 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, and/or they can lodge themselves into your oil pickup, starving your engine of oil. We've even seen cases where the belts snap, wrap themselves around your crank pulley and force the The entire belt into the engine, through the crank seal! If either of these situations occur, you'll be looking at a costly new engine, which will cost thousands of fees
The Crank Seal Plate is a preventative measure application designed to protect the front crank seal and prevent the belt and belt fragments from entering the oil pan through the front crank seal in the event of a serpentine belt breakage, saving your engine!
Made of high quality CNCaluminum, which is strong and durable, anti-rust and anti corrosion. Ultra precision machine cut for super light weight construction; high precision and quality.
This Crank Seal Protection Cover is a preventative measure application designed to prevent the belt from entering the oil pan through the front crank seal, in the event of an serpentine belt failure. 2.These are made out of a chunk of solid billet aluminum, All which hold steady and tight tolerances. These will be stronger than welded versions that have been showing up recently, much higher quality, and are cheaper than the other billet versions.
Of course, there are other obvious preventative maintenance items to replace such as the oil filter housing and oil cooler housing gaskets, new tensioner and pulleys and belt, new motor mounts, etc.. that will all help prevent the belt from snapping and should be done anyways at some point. But they still snap, whether it’s due to the tensioner failing randomly, or an oil or coolant leak. We still see cars with snapped belts and blown motors.

Nice seal. Belts not getting in there

When installed it doesn’t sit flush with the block so the crank pulley will rub on it. Might just be mine but it is unusable, the part seems to be quality though mine just doesn’t fit properlyUpdate:The company reached out to me and sent me another one without question to make it right. Great customer service and product, I just got an off one I think. Buy with confidence!

This is a great idea. It is designed to protect the front main seal of BMW N52 engines (mine is 2010 328i) in the event the serpentine belt breaks. This was a design flaw by BMW. When this happens, little shards of the belt get pinched between the vibration damper and the main seal and get forced into the oil pan. If enough material gets into the oil pan, the oil pickup tube becomes clogged, oil pressure goes to zero, the engine seizes, and the engine is essentially shot (requires major repair work that often costs more than the car is worth). All of this happens without the owner necessarily knowing it has happened.The problem, which can be seen in the attached pictures, is that the thickness of the bolting surface (circled in blue above) is too thick which causes the bolt head to scrape against the inside of the vibration damper. When I put the vibration damper on, I could barely hand crank with a breaker bar and this is why. The vibration damper was scored. I had to grind the bolt heads down so that the vibration damper could rotate freely. I think my modified version of this will work. Hope this helps someone.
