Worn valve guides can cause oil consumption, usually seen as blue smoke on start up.
The clicking you hear is a sign the valve lash needs to be adjusted. The loose ones are making the noise, but there could be some tight ones. The tight ones cause compression loss and will eventually damage the valves. It is a simple procedure to set the lash and needs to be done before running a compression test. They set at .015 hot.
