Ford F-150 2017 Turbo ecoboost 3.5 200000 miles
At the start, engine has a sound like hitting something, and after a couple minutes, warning low oil pressure, but back to the normal when I accelerate, sometimes appears the warning in high rpm (2500) and doesn't recover with the gas pedal. I have codes of crankshaft position sensor problems. I'm thinking to replace timing chain, but before start, any advices?
