The oil pressure gauge on the dash shows no oil pressure. I do know that it burns oil and has oil leaks. I use 15w40 in it. Between leaking and burning oil I use about 2 quarts in between oil changes The rear valve cover is leaking and so is the oil pressure sending unit. Both issues will be addressed soon. On previous cars I've own when the oil pressure sending unit goes bad the oil pressure would be maxed out. Would the oil pressure sending unit fix the low oil pressure or do I have another problem?
