What are the effects of a faulty exhaust camshaft solenoid valve in the LaCrosse?

[DiKimberly]

Effects of a faulty exhaust camshaft solenoid valve in the LaCrosse: 1. The camshaft is located almost at the end of the engine lubrication system, so the lubrication condition is not optimistic; 2. The oil pump may have insufficient oil supply pressure due to prolonged use or other reasons; 3. Blockage of the lubrication oil passage prevents the lubricant from reaching the camshaft; 4. Excessive tightening torque of the bearing cap fastening bolts prevents lubricant from entering the camshaft clearance, all of which can cause abnormal wear of the camshaft. The LaCrosse is a mid-to-high-end sedan introduced by Shanghai GM, with body dimensions of 5005mm in length, 1858mm in width, and 1500mm in height, and a wheelbase of 2837mm. In terms of appearance, the LaCrosse is more grand and luxurious, featuring a large three-dimensional shield emblem on the front, a wide chrome-plated front radiator grille, and prominent cannon-shaped taillights.
