Check oil level maybe low on oil. If full and still knocking either timing is off or bad rod bearing.

Just had oil change.. not low. Any other tips please. It's getting louder every time I drive it. Thank you

Yes..thank you. Can't be oil issues. Maintained regularly and changed recently. Is this "rod" an expensive job?

is it a knock for sure or a timing ping????

Check your anti freeze level. If it is low it is a rod knock I know this because just worked on a vehicle that run low on anti freeze and the rod bearing started knocking. On that vehicle I replaced the rod bearings by lifting front end and supporting it and removed oil pan and replaced rod bearings do not know if all vehicles can be done this way.

Is your check engine or service engine soon light on? If so it could be the knock sensor. The knock sensor is like a microphone that listens for spark/knock. When it hears it a signal is sent to the computer (PCM) to retard the ignition timing and stop the spark/knock. As far as it being a rod knock, at 16 years old, it could very well be. Everything wears out sooner or later no matter how well it's taken care of. But let's hope not!! HTH. -Jim
