SERVICE INFORMATION
On some 1990 300ZX vehicles, customers may complain of oil leaks, lack of timing belt tension, or a noise (high pitch or squeal) coming from the front
of the engine.
To improve the durability of the auto tensioner, several design changes have been made:
Figure 1
^
The material for the oil seal has been changed to a fluorine-type resin compound to prevent oil leakage.
^
The oil passage for the auto tensioner has been relocated (Figure 1).
^
The clearance between the body and the piston has been reduced.
