Loud ticking noise after replacing spark pugs

Hello,

Make sure that either your spark plug wires or Coil On Plugs (COP)(s) are securely pushed down on the spark plugs. The ticking that you are hearing could be that either the spark plug wire or the COP isn't on the spark plug all the way and is arcing causing the ticking noise.
Please get back to us with what you find out.

Thanks,

Hello again,

Check your engine oil level. This could be coming from your valve cover and is probably a lifter that is not getting oil or is stuck. A good way to narrow this down is to get a long screwdriver or a socket extension and place it on the valve cover next to where you here the ticking. This will act as a sort of "stethoscope" and allow you to hear what is going on. Also is your Malfunction Indicator Lamp (MIL) or "check engine" light illuminated?

Thanks,
