    Engine rattle, noise behind cluster.

    Good morning guys,

    My STS seems to have a very odd engine rattling noise and i cannot seem to figure out what is causing this. The noise itself sounds like a rattling/ticking noise almost like a valve moving. The sounds is coming from the engine compartment on the drivers side right by the firewall, sounds like its coming from behind the cluster when driving the vehicle, the sound can also be heard when standing outside the vehicle. The ticking/rattling is also engine RPM dependent meaning that the ticking noise will increase in speed or decrease in speed depending on engine rpm. The noise is getting really annoying but seems to have no effect on vehicle drivability.

    This is a long shot but it kind of sounds like a PCV valve? I replaced a PCV valve in my regal(3800) last year and when i had the valve in my hand i would shake it to ensure that the valve was moving freely and the sound that it made is almost identical to the noises that i am hearing. Anyway i was hoping somebody with a bit more experiance could chime in and lead me in the right direction, thanks in advance.

    V6's have a known issue that meets your description. What have you got under the hood?
