Regulator Valve Clearance

WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Clearance 6 = (regulator valve hole diameter D) - (outer regulator valve diameter E).
If the calculated clearance 6 exceeds the standard, replace the oil pump body.
Clearance 6 : 0.040 - 0.097 mm (0.0016 - 0.0038 in)
CAUTION:
- Coat the regulator valve with clean engine oil.
- Check that it falls smoothly into the valve hole by its own weight.
