Nissan Repair: 1995 Nissan Sentra 1.6L compression, engine leaks, nissan sentra

Question
What is the rated factory cylinder compression for this engine if it is a new or rebuilt engine?

Answer
Ron,

Something like 120 if old and 160 if it is rebuilt or new.  The basic thing is you want no more than ten percent between cylinders for the compression test.  Use Mobil 1 synthetic 5W30 oil to get more power and better ring sealing.  If your seals are worn and the engine leaks use Penzoil 5W30 regular oil.  Synethetic will find weak seals...
