no noise engine running ok/ for the last 8 month engine would smoke a little when you first crank engine
Chevy Mechanic: Gary, Chevy Technician replied 2 years ago

did the confirm the oil pressure being too low or under spec with a mechanical oil pressure gauge connected to the engine ?

why are they saying it needs a new engine i mean what are they saying is failing or had failed ?

Customer reply replied 2 years ago
oil pressure low with mechanical oil pressure gauge/was told that it was a internal problem
Chevy Mechanic: Gary, Chevy Technician replied 2 years ago

usually with NO engine noise at all this issue will be lower end bearings that have opened up or the oil pump or oil pump pick up tube O-ring failure

dies this engine have cylinder deactivation where it can shut off cylinders when driving for active fuel management ?

has cylinder deactivation
Chevy Mechanic: Gary, Chevy Technician replied 2 years ago

what they need to do is test the oil pressure at the bottom end where the oil filter screws on the engine they have screw on oil filter testers for this and see if the oil pressure is still low reading the pressure at the oil filter housing

if it still reading low then its one of the things i said

if it reads GOOD at the filter housing but NOT good top of the engine then the small filter under the oil pressure switch is usually the issue and needs to be changed
