Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, I will try my best to help you with your concern. First I am not standing in front of your vehicle. I can't see or hear what you are experiencing. I will try to give you my best educated guess with the information you give me.
can you isolate the noise to the camshaft sprocket/ timing belt area?
helps some yes thank you. Has the timing belt been replaced? do you see excessive freeplay in the timing belt?
