Kia Troubleshooting Questions? Ask a Mechanic
Hello, my name is Bobby. Thank you for the question. Does the noise change if you rev the engine or as the engine warms up?>
Thank you. It may be a lifter but that is not too common. Most of the time it is a cam adjuster problem or possibly a sludge issue. How many miles are on it?
The cam phaser itself can be failing, but I have had issues with the oiling system also especially if you are using a cheap quality aftermarket oil filter. Can you pinpoint a certain area that the noise is coming from?
