My motor had started ticking a bit back in September 2018 I added some oil and it went away. Then, in January 2019 I had engine codes. Plugged my scan tool in and said I needed both camshaft sensors, misfire on cylinders 1, 3, & 7. Replaced all 8 plugs and coils, motor had 123xxx miles. Drove another 4000 miles and the same problems persisted and got worse. I took it to a mechanic for a diagnosis on the misfires and engine tick, come to find out it is a �lifter tap�, shavings of aluminum in my oil and plugging up the lifters. Mechanic said to get a new motor, don't both trying to fix it. I bought it used with 119xxx and truck ran fine in August of 2018.
