What are the causes of abnormal noise in the Leiling 1.2t engine?
3 Answers
The causes of abnormal noise in the Leiling 1.2t engine are: 1. Excessive clearance between the piston and cylinder wall; 2. Excessive viscosity of the engine oil; 3. Insufficient belt tension; 4. Excessive carbon deposits on the valves or incorrect timing adjustment. The Leiling 1.2t is a 4-door, 5-seater sedan produced by GAC Toyota, with body dimensions of 4640 mm in length, 1780 mm in width, and 1455 mm in height, a wheelbase of 2700 mm, and a fuel tank capacity of 50 liters. The Leiling 1.2t is equipped with a 10-speed continuously variable transmission, delivering a maximum horsepower of 116 hp, a maximum power of 85 kW, and a maximum power speed of 5200 to 5600 rpm.
My Levin 1.2T engine is making abnormal noises, which has me quite worried. As an experienced driver who has been behind the wheel for several years, I think the possible causes include a few points. First, the timing chain might be loose or worn out, which would sound like a rattling noise, especially during cold starts. If there's an issue with the turbocharger, such as stuck turbine blades or poor oil flow, it can cause a ticking or whistling sound. The belt system shouldn't be overlooked either—worn tensioner pulley bearings or a loose alternator belt can produce a squealing noise. Loose engine mounts can also lead to resonance noises, particularly during low-speed turns. Additionally, lubrication problems, like insufficient or poor-quality oil, can increase friction between components. I believe this isn't something to take lightly. It's best to head straight to a 4S shop or a trusted repair shop for an inspection. Don't just rely on online advice—check the chassis stability yourself. Safety comes first.
As a tech-savvy car enthusiast who loves tinkering, I've studied the abnormal noises in the Leiling 1.2T engine. The core issue might be mechanical component problems. A loose timing chain causes a rattling sound; blockages in the turbocharger's intake/exhaust system create abnormal airflow, sounding like whistling; worn belt tensioners or water pump bearings produce sharp friction noises; aged engine mount rubber leads to vibration noises; and faulty oil pumps cause insufficient lubrication, worsening component friction. I recommend first scanning for OBD2 trouble codes with a diagnostic tool, then checking belt tension and chain tightness. Additionally, excessive carbon buildup in the cylinder head can cause clicking sounds—try adding high-quality fuel additives. If there's no improvement, get it repaired promptly to prevent the issue from worsening.
