Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
Sludge in the motor will cause this as well as a bad oil pump. Check the oil pressure with a gauge. If the pressure is good and there is no sludge, then you need a new oil pressure switch.
Once you have done my suggestions, you will know what is wrong, and NO to your other concerns.
