How To Detect Unseen Damage To An Engine? – Engine Camera Scope
Many critical components inside the engine are "hidden" inside the metal casing and are completely invisible to the naked eye. Traditional methods often rely on fault codes, listening to the engine, and experience to make a diagnosis, and in severe cases, it may even be necessary to disassemble the engine to confirm the problem—which is not only time-consuming and labor-intensive, but also increases customer costs and repair risks.
It is against this backdrop that engine cylinder borescope have gradually become an important inspection tool in modern auto repair shops. Simply put, it’s a specialized device that allows you to "see inside the cylinder" without disassembling the engine. An endoscope typically consists of a long, flexible probe with a miniature camera and light source at the front and a display screen or mobile device at the rear. Technicians can insert the probe into the cylinder through the spark plug hole, fuel injector hole, or other inspection port to observe the piston top, cylinder wall, valves, and combustion chamber in real time, determining if there is carbon buildup, cylinder scoring, wear, foreign object residue, or abnormal combustion traces.
1. Three Common Types of “Hidden Faults” in Repair Shops
Many cars bring in with subtle symptoms, such as:
- Cold start vibration
- Insufficient power
- Oil consumption
- Misfire or cylinder misfire
- Engine malfunction light illuminated
If the engine is disassembled directly:
- High labor costs
- High risk
- Customers are unwilling to pay
However, if a borescope cylinder inspection is used, the repair shop can first assess the problem before deciding whether to disassemble, significantly reducing misdiagnosis and rework.
- Carbon buildup on piston crown
- Scratches or marks on cylinder walls
- Carbon buildup on valves
- Early signs of piston breakage
- Oil burn marks
- Coolant leaks (emulsion spots)
👉 Core value: Visibility = Accurate diagnosis
2. Standard Inspection Procedure for Engine Cylinder Borescope
Step 1: Prepare the Vehicle
- Turn off the engine
- Remove the spark plugs (gasoline vehicles) or fuel injectors (diesel vehicles)
- Ensure the battery is fully charged to avoid power loss during the inspection
Step 2: Insert the Engine Camera Scope
Gently insert the engine camera scope into the cylinder, adjust the flexible lens, and check the following in sequence:
- Piston top
- Cylinder wall perimeter
- Valve area
The advantages of the AUTOOL SVB series endoscope are evident here:
- Narrow-diameter lens, easy to access narrow cylinder blocks
- Flexible probe, allowing visualization of sidewalls and corners
- High-definition image, facilitating the assessment of minor damage
Step 3: Problem Recording and Customer Feedback
By using the endoscope, repair shops can achieve the following:
- Save photos
- Record videos
- Mark problem points
This step is crucial: it serves as “evidence” for subsequent repair quotes.
3. When is a borescope cylinder inspection mandatory?
Repair shops are advised to prioritize endoscopic inspection in the following situations:
- Abnormal engine noise with no identifiable cause
- Abnormal compression ratio
- Severe oil consumption
- Suspected water ingress into the engine after vehicle submersion
- Severe carbon buildup from prolonged short-distance driving
- Used car appraisal
This is not only a technical measure but also a risk control measure—avoiding unnecessary major repairs.
4. Why do repair shops need their own engine borescope for sale?
If inspections are outsourced every time:
- High cost
- Slow response time
- Customer loss
But owning an engine borescope for sale (an endoscope that can be used long-term):
- On-demand inspection
- Enhanced professional image
- Enables more repair services (cleaning, disassembly, parts replacement)
👉 Endoscope = a diagnostic gateway, not just a tool.
