Inline PRO Race Spec F20C/F22C Timing Chain Tensioner

As you may already know, there are many problems \nassociated with the stock timing chain tensioner. \n \nHere are some of the most common problems \nthat develop with the stock unit: \n \n-The timing chain stretches and the guides wear over \ntime creating excessive slack in the overall assembly. \n \n-When throttle is lifted after a high rpm pull, the sudden \nchange in momentum causes excessive slack in the timing chain. \nThis also causes a sudden change in oil pressure \nin the stock tensioner. \n \n-Sudden downshifts in the transmission or engine braking also \nfurther exaggerates the slack in the chain mechanism. \n \n-Installing higher tension valve springs and high lift \ncamshafts will also contribute to the problem with chain slack. \n \n-The most common problem is the noise associated with start-up \nand idling, which has to do with lack of oil pressure behind \nthe tensioner piston and excessive wear on the worn screw gear.
