A few months ago I bought a loaded Lincoln MKZ with the 3.0 twin turbo with 400 HP and 400 Torque. Come to find out a small number of these cars left the factory with a small defect in one of the heads and from what I understand it causes oil to not drain back to the motor properly and starves the engine from proper oiling. So at just about 12,000 miles the check engine light came on and the dealer checked it Lincoln told them to pull the plugs and check the compression. Cylindar number 4 was down 7% and 1&3 were down 5% anyway the dealer said Lincoln will be ordering me a new engine.
