Audi 4.2L Complete Timing Chain Kit
Audi’s 4.2L V8 is a complex engine driven by a series of chains connecting the camshafts, crankshaft, and intermediate shafts. In order for the timing system to function, the timing chains ride on a series of guide rails and are tensioned by several hydraulic adjusters. As the engine begins to age, guide rails begin to deteriorate and hydraulic adjusters no longer provide the same tension they once did. This causes excessive slack on the timing chains and will create a distinctive noise in the engine compartment. Eventually a catastrophic failure will occur, leading to very costly repairs.
USP has carefully assembled a complete timing chain kit which includes all the components needed to restore your engine’s timing system to its original state. USP recommends performing a timing chain service at approximately 105,000 miles or sooner if noise is audible from your engine’s timing system.
