I have a ticking noise coming from the bottom of engine near passenger side. I replaced oil and four camshaft sensors. Still have the ticking noise. Need help with advice or illustration on what to look for. Thanks.

Hello,

This could be a hydraulic lifter that has gotten plugged and is not pumping up. Your vehicle uses hydraulic lifters in the valve train to maintain the valves and it is pumped up by engine oil through a tiny hole to let the oil in. Sometimes these little holes get plugged and wont allow the lifter to pump up. But, I have included a link for you to go to below:
