my oil light flashes every now and then.. sometimes when i start my vehicle!! but oil pressure switch is new.. and car is full of oil..

 

Sounds like you need to test it with an actual gauge. You may have a bad oil pump, or bearings that are loose to the point that oil pressure is not building well.

Be very careful if you start hearing noise from the bottom end, a spun bearing or worse may soon follow.

 

Sno has it. Oil pump is bad or is going bad. I would not drive until its fixed. Spun bearings are NOT fun.

 

thanks guys.. i think its time for a k swap!!!
