Engine ticking noise 3.4L GM 3400 SFI V6

Engine ticking noise GM 3400 SFI V6 2006 Pontiac Torrent/Chevy Equinox

Any ideas why? Ticking frequency increases as the engine rev up, car runs normal, all fluids levels ok, synthetic oil 5w30 and OEM oil filter used as per manual. Sounds like the noise comes from valve cover area. Does not get better when engine warms up. 120000km

worn internals do that, often worn hydraulic lifters or valve wear . It costs a lot to repair engines, and if it runs good, I'd drive it till it drops myself. GM makes lower quality engines these days
