What to Do About Timing Chain Noise?

[AveryAnn]

Solutions for timing chain noise include: 1. Replace the tensioner; 2. Replace the chain; 3. Replace the chain guide; 4. Check if the lubrication system is faulty; 5. If the noise is caused by low oil pressure, the noise will be louder at idle and reduce when accelerating. The method for replacing the timing chain is: 1. Remove the valve cover, detach the crankshaft pulley, and take off the timing chain cover; 2. Rotate the crankshaft to the top dead center of the first cylinder, then tighten the crankshaft fixing screw to secure it; 3. Rotate the intake and exhaust camshafts—there are grooves at the rear of the camshafts—align the grooves of both camshafts evenly, and insert the specialized tool; 4. Remove the old chain and install the new one.
