What causes the abnormal noise in the Baojun 730 engine during cold starts?

[FaithAnn]

Baojun 730 cold start engine abnormal noise is most likely caused by insufficient lubrication during cold starts. Below is relevant information about the Baojun 730: 1. Sufficient space: The Baojun 730 has a length of 4780mm, width of 1820mm, height of 1755mm, and an ultra-long wheelbase of 2750mm, giving it a very spacious interior compared to other vehicles in its class. 2. Excellent power: The Baojun now features a 1.5T turbocharged engine with the code name 260T, paired with a brand-new CVT transmission, while also being fuel-efficient.

I've been driving my Baojun 730 for a while now, and when starting the engine cold, it makes squeaking or rattling noises, commonly caused by issues with the valve lifters or timing chain. In cold weather, the engine oil's fluidity decreases, leading to insufficient lubrication of parts, which causes those metal components to rub directly against each other and produce noise. Additionally, aging belts or loose tensioners can also result in similar sounds. I recommend first checking if the oil viscosity is suitable for the local climate—too thick or too thin can both be problematic. Try switching to full synthetic oil, as it can improve startup lubrication. Regular maintenance is crucial; don't skimp on that bit of money, or prolonged noise could affect the engine's lifespan. My car had the same issue before, but after changing the oil, it improved significantly, and now it starts up quietly. In short, address such problems early to avoid small issues turning into big ones and wasting more money.

The cold start abnormal noise of Baojun 730 is quite common. I believe the main reasons lie in the engine oil or the belt. In cold weather, the thick engine oil doesn't easily reach the components, causing the valve lifters to sound like metal knocking. Sometimes, a loose timing chain can also produce a ticking noise. If the belt is aged or cracked, the friction can create even louder sounds. It's recommended to let the car warm up before starting and avoid stepping on the accelerator immediately, giving the lubrication system some time. Using low-temperature engine oil like 5W-30 might be better. If the noise persists, don't tough it out yourself; take it to a professional repair shop for inspection, which is both cost-effective and safe. Ignoring abnormal noises can lead to severe engine wear over time, resulting in higher repair costs and even the risk of breaking down on the road, which is dangerous. Paying attention to your car's condition daily can save you a lot of trouble.

As a long-time owner, I've encountered the cold start abnormal noise issue with the Baojun 730 multiple times. This is usually caused by hydraulic lifters or timing chains. With less lubrication during cold starts, parts may rub and make noise - don't panic. First try switching to a suitable engine oil. Regular maintenance can prevent these issues; don't wait until the noise becomes severe to fix it. Safety first - if you notice problems while driving, pull over and inspect immediately.

The Baojun 730 makes abnormal noises during cold starts, such as squeaking or clicking sounds, which may originate from valve lifter issues or belt problems. In cold weather, the engine oil thickens, leading to insufficient lubrication and direct contact between parts, causing noise. Worn timing chains can also produce such sounds. It is recommended to check the oil dipstick yourself to see if the oil level is normal; if the belt shows visible cracks, it needs to be replaced. Visit a repair shop as soon as possible for inspection and repair to avoid further internal engine damage. Proper maintenance extends the vehicle's lifespan, saving money and being environmentally friendly.

My Baojun 730 often makes a ticking noise during cold starts, mainly due to insufficient lubrication of the valve tappets or timing chain. Engine oil flows slower at low temperatures, increasing friction between metal components and amplifying the sound. Checking the oil viscosity and switching to winter-specific oil can help alleviate this. A loose belt may also cause squeaking, making timely replacement crucial. Ignoring these noises could potentially damage the engine, so addressing them early ensures safety and peace of mind.
