: Engine ticking noise

04-30-13, 01:48 PM
As a first time Cadillac and American car owner my ATS with 2300 miles when I am out of the car I notice a ticking sound from the engine (3.6 l) compartment. Dealers says this is normal. Any confirmation of that

yeah I've heard its got something to do with the Fuel injectors or something like that.. but it is normal, the 3.6 impalas and equinox' do it

the 3.6 sounds like a lifter needs adjusting, but it is the extreme high pressure direct injectors opening and closing, every DI engine I've come across has this to some extent.
