Contrary to popular belief, the true reason it is so common for these engines to end up either spinning the oil pump nut off the pump shaft or breaking the shaft is not engine harmonics. It is chain slack whipping back and forth at high rpm's, abusing the oil pump, sprockets and shaft. BMW did not use a tensioner, as they did in their race cars, to save costs over the course of millions of production engine builds. The common solution is a oil pump shaft upgrade, however, to fully bulletproof your engine and fight against oil pump failure, chipped sprockets and chain wear use a tensioner. \u003cbr\u003e\u003cbr\u003eThe chain tensionser is the only product of it's kind for this application, and uses a polymer tensioner against the chain, stopping the chain slack from damaging the oiling system during high rpm's. The tensioner is a tested a piece which is produced and used on other OEM vehicles, and repurposed to be used in this application.
