SERVICE INFORMATION

Some VE30DE engines installed in '92 and '93 SE Maxima's may exhibit top end noise. Although the noise is often described as "lifter noise", it is rarely caused by the hydraulic lash adjusters. There are four identified sources of this type of noise. In order of probability, the noise may be caused by: (1) the VTC sprocket, (2) the upper timing chain tensioners, (3) debris in the cylinder head oil galleys restricting the oil supply to the VTC sprocket or chain tensioner, or (4) misalignment of the cylinder head camshaft bearing caps. An improved VTC sprocket has been developed to resolve many of the noise incidents.





Use the flow chart to diagnose the source of the noise. Refer to the procedures below to perform the actual inspections and repairs.
