Timing Area Oil Leaks On 1990 Nissan VG30 Engines |
|
When checking for the source of an oil leak in the timing cover area of 1990 Nissan VG30 engines used in 300ZX automobiles, be sure to check the auto tensioner for leaks. Nissan has revised the auto tensioner, Part #13070-45V01, by relocating the oil holes and reducing the clearance between the tensioner body and piston (see illustration). The new tensioner is available under Part #13070-45V03. Rebuilders should verify that only the revised auto tensioner is installed on rebuilt engines
