I have a knocking noise in the engine Mechanic's Assistant: Where exactly do you think the noise is coming from? And how long has this been going on? No idea and since last month Mechanic's Assistant: What is the make/model/year of your car? Hyundai [sonata](/topics-sonata/) 2008 Mechanic's Assistant: Are you fixing your Sonata yourself? What have you tried so far? I heard putting oil stabalizer would help it Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I did a code reading and it was “p0011”

Thank you. Give me a few minutes so that a can pull up your vehicle.

You get it ?Okay thank you
Automotive Expert
Ok it sounds like you may have bad crankshaft bearings. But before we deadline the engine I attached a TSB which states to replace the oil filter with a hyundai oil filter if you still have knocking then remove the accessory belt to make sure its not the A/C compressor or any other belt component. With the belt removed start the engine and listen for the knock. If you still hear is then you may need an engine.

Yeah i already did an oil change with the oil filter and added oil stabilizer but ill do that as soon as i get home. For sure before 5 and ill keep you updated
Automotive Expert
Ok I'll keep this open for a week for your response. Take your time

You dont think it has to do anything with the camshaft. I did a code reading on it. The code was p0011
Automotive Expert
Is it a knocking or tapping?

Would say tapping
Automotive Expert
Ok let me check again.

Okay appreciate you
Automotive Expert
Ok check the oil and make sure its full. If its full then looks like you may have to change the intake varable timing solenoid. According the Hyundai the intake VVT adjusts the timing and will set P0011 if the solenoid fails.

Automotive Expert
Let me know how it goes.

I will thank you
Automotive Expert
No problem

What does it mean if i try starting it and its resisting or turns off. Before i even did anything to it
Automotive Expert
If it doesn’t want to start then the timing may be off.
