Nissan Repair: 1994 Nissan Bluebird 2.4L, valve cover gasket, nissan bluebird

Question
1994 Nissan Bluebird 2.4L has intermittent flucuations in revs whislt idiling/stationary, also has slight but constant oil leak in the timming cover oil pump area.

Answer
Bill,

First, perform a tuneup by replacement of sparkplugs, wires, cap and rotor.  I bet the intermittent issue is that the distributor has oil on the optics.  The front cover and seal issue is common and will have to be addressed by replacement of the valve cover gasket, the timing cover gasket and the front seal.
