I have 2011 Elantra Limited. for months now when first started engine taps, like a valve tap, this disappears after engine is warm. first I was told it was aftermarket oil filter. then I was told it was cam phasers/lifters. still at dealer and they are unsure at this point. anyone else experience this?

It must have been a well pronounced tap for them to justify engine replacement. Mine does this at start up but not really loud enough for it to be a problem and disappears after 30 seconds literally.I have had many vehicles and most all of them tapped at start up and went away. Anyway congrats on the new elantra heart replacement :D
