2 Answers
The symptoms of a faulty exhaust valve in the Excelle are: 1. Blue smoke coming from the exhaust pipe; 2. It can lead to burning engine oil. The exhaust valve is also known as the oil separator or pressure control valve. The Excelle has a body size of: length 4609mm, width 1798mm, height 1486mm, with a wheelbase of 2640mm and a fuel tank capacity of 44 liters. The Excelle is equipped with a 1.3T turbocharged engine, delivering a maximum horsepower of 163 hp and a maximum power of 120 kW, with a maximum power speed of 5500 rpm. It is paired with a 6-speed automatic manual transmission. The front suspension type is MacPherson independent suspension, and the rear suspension type is multi-link independent suspension.
I remember once the PCV valve in my Buick Excelle went bad, and the symptoms were quite noticeable. The engine kept shaking violently, especially when idling at a stop, making the steering wheel tremble like it was drunk. Fuel consumption was significantly higher than usual—burning through more gas over just a few hundred kilometers, which really hurt the wallet. Performance-wise, the car felt sluggish when stepping on the gas, accelerating painfully slow, making overtaking a struggle, and it often stalled. The worst part was the persistent engine warning light glowing yellow, along with weird-smelling exhaust fumes that felt bad for the environment. The most annoying issue was cold-start difficulties—struggling to fire up on winter mornings, requiring multiple attempts. I’d recommend getting it checked at a repair shop early to avoid worse damage, like harming the exhaust system, which would cost even more to fix. Regular maintenance can prevent this—just inspect the PCV valve for dust buildup or clogs, and a simple cleaning can save a lot of hassle.
