I am sorry your having this problem

Expert:  Gary replied 1 year ago.

is the engine making noise at all ?

Customer: replied 1 year ago.
no noise engine running ok/ for the last 8 month engine would smoke a little when you first crank engine
Expert:  Gary replied 1 year 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: replied 1 year ago.
oil pressure low with mechanical oil pressure gauge/was told that it was a internal problem
Expert:  Gary replied 1 year 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 ?

Customer: replied 1 year ago.
has cylinder deactivation
Expert:  Gary replied 1 year 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
