Engine Mechanical problem
2003 Nissan Xterra 6 cyl Four Wheel Drive Manual 140, 00 miles
Just experinced an oil leak on on the driver side valve cover after driving the car 3 miles after a 3 min warm up in the morning when overnight temps hit 0 degrees.
In the 3 mile drive the RPMs were kept down and speed did not go over 35 mph or rpms above 2300rpm.
Oil has leaked a few times from the driver side valve cover last year and was repaired 3x. Each time the the overnight temps were low ( below 10degrees) Am not sure if engine was"warmed up" prior to driving though, more than likely it was.
Last repair to valve cover included a new cover and correct screw from nissan and new gasket. Engine compression was normal.
Oil right now is 5w30castrol synthetic. Oil was changed 800 miles ago with new filter.
Oil leaking from driver side valve cover is reoccuring,
but why? FYI it has dropped several times to zero and below and there has been no issues.
FYI 6 weeks ago oil was found in engine a minor amount. It seemed teh oil dip stick "popped out" about 2 inches from it seating. That was attributed to the engine nto being allowed to warm up. Rpms at warm up were 1900rpm, oil was changed the day after and intial start up rpm returned to 1500 rpm.
have the same problem?
