Calculation of Camshaft Journal Clearance

WARNING: This page is about a different car, the 2005 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.

(Journal clearance) = (camshaft bracket inner diameter) - (camshaft journal diameter)

Standard: 0.030 - 0.068 mm (0.0012 - 0.0027 in)

If measurement is not within specification, replace either or both camshaft and cylinder head.
