I have noisy hydraulic valves and tappets, can ZX1 help?
We cannot say hand on heart that treating with EXTRALUBE ZX1 will totally cure the problem but it certainly will reduce noisy hydraulic valves and tappets in most cases, in fact some garages use it for that specific purpose especially one who comes to mind specializing in Audi and VW vehicles which tend to suffer this problem. If there is a leak in the system, which allows the oil to leak out of the valves when the engine is shut down, it will be difficult to eliminate the initial metal-to-metal hammering sound until the system is full of oil again cushioning the valves.
