Loud Ticking/ Knocking sound

Asked by Feb 05, 2017 at 08:02 AM about the 2004 Chevrolet Cavalier LS

Question type: General

Initially when those nose started about two months
ago, it goes off when I go for an oil change so that
gave me an assurance that it may be a dirty oil.
Now I just did an oil change and the ticking/
knocking sound coming from the passengers side
of the engine cabinet is loud and non- stop

If it's loud then most likely the rod bearing that was loose has finally let go all together, driving it now wil detonate the engine and you won't have a core to go with a replacement engine. Any ticking/knocking noises should be checked out right away to prevent a problem like this.

Let a mechanic diagnose the noise, if it's from the valvetrain (lifters of valves) it can be fixed relatively inexpensively, but if it's the lower end (crank, rods, pistons) it probably won't be worth fixing given the age and type of car. Usually if the ticking matches engine RPM it's from the lower end, if it seems like it's one-half engine RPM it can be from the valvetrain.
