What is a sign of leaking valve seals on a 5.7 liter hemi?

A sign of leaking valve seals on a 5.7-liter HEMI engine is increased oil consumption, often accompanied by blue smoke from the exhaust, particularly during startup or acceleration. Additionally, you might notice a rough idle or a decrease in engine performance. If there's a buildup of oil around the valve covers or a significant amount of oil in the intake manifold, these can also indicate failing valve seals.
