Motor has two collapsed lifters making a chattering noise.
Motor hesitation when driving slowly in traffic. Rough riding.
Bad gas mileage.
Automatic locks are going off, lights flashing when in traffic, just sometimes.
Ford should be more careful when designing motors.
My explorer just turned 108,000 miles and started making knocking noise. Ford dealer charged almost $200 to tell me that there is "lazy lifter." To fix it, they charge $4,500!!! RIDICULOUS!
Lifter noise does not mean a bad motor. Just use thicker oil like 20w50 and you should never hear that lifter noise again.
