My 2013 Ram has a 4.7 V8 and makes a tapping noise until warmed up.
The truck makes a distinct tapping noise like a bad lifter until warmed up. The dealer says they have performed all Chrysler recommended tests and there is nothing wrong with it. So what is causing this noise.
You are right,weak lifter,or bad oil pressure will cause this issue,the dealer must think it will tap long enuff for your warranty to be void,don,t wait for this,push the subject of the warranty,and that your 2 year old truck should not have any tapping in the engine.
