1 Answers
The following are the reasons why the Camry suddenly beeps while driving: 1. Excessive clearance between the piston and cylinder wall: The abnormal sound only occurs during idle or low-speed operation. Possible causes include: excessive clearance between the piston and cylinder wall; overly tight piston pin assembly or connecting rod bearing assembly; excessive clearance between the tappet and its guide hole; wear of the cam profile. 2. Valve train malfunction: Abnormal sounds caused by the valve train may result from: excessive valve clearance; excessive clearance between the tappet and its guide hole; wear of the cam profile; excessive clearance between the valve stem and its guide; broken valve spring; radial fracture of the camshaft timing gear; loose valve seat ring; stuck valve that cannot close.
