When buying a used engine, one question matters more than any other:
What has actually been checked before the engine is sold?
At Auketra, inspection is not a formality—it is the core of our work. We do not sell engines "as removed." Every engine goes through a structured, professional inspection process before being approved for sale and warranty.
This article explains exactly what inspections are performed on used engines at Auketra, step by step.
Why a Structured Inspection Process Is Essential
A used engine can fail for many reasons, even if it appears clean or has low mileage. Internal wear, lubrication issues, or hidden damage often remain invisible without proper tools and expertise.
Our inspection process exists for one reason:
👉 to eliminate risk before the engine reaches the customer.
Step 1: Engine Identification & Compatibility Verification
Before any mechanical inspection, we verify that the engine is 100% compatible with the customer's vehicle.
This includes:
- Exact engine code verification
- Vehicle make, model, and production year
- Fuel type and emission standards
- Technical configuration (mounts, sensors, accessories)
This step prevents costly installation errors and incompatibility issues.
Step 2: Mileage and Vehicle History Review
Whenever available, we analyze:
- Verified mileage from the donor vehicle
- Maintenance and service history
- Reason the vehicle was dismantled (accident, non-engine-related issue, etc.)
Mileage alone does not define engine condition, but it provides essential context for deeper inspection.
Step 3: Pre-Removal Engine Condition Check
Before the engine is removed from the vehicle, we assess:
- Overall engine behavior
- Signs of abnormal noise or vibration
- Evidence of oil or coolant leaks
- Visual signs of overheating or mechanical stress
This step helps identify early warning signs before dismantling.
Step 4: Post-Removal Visual Inspection
Once removed, the engine undergoes a detailed external inspection.
We check for:
- Cracks or damage on the engine block
- Condition of seals and gaskets
- Broken or damaged mounting points
- Oil residue patterns indicating internal issues
Any engine showing structural or critical damage is immediately excluded.
Step 5: Mechanical Testing (Compression & Leak-Down)
Mechanical testing is a critical part of our process.
We perform:
- Compression tests to measure cylinder sealing
- Leak-down tests to detect valve, piston ring, or gasket issues
Engines with irregular or unsafe test results are rejected.
Step 6: Internal Engine Inspection (Endoscope Camera)
To see what the eye cannot, we use an endoscope inspection camera to examine the inside of the engine.
This allows us to inspect:
- Cylinder walls
- Pistons and combustion chambers
- Valves and internal surfaces
- Signs of scoring, wear, or overheating
This step often reveals issues that would otherwise go unnoticed.
Step 7: Oil Analysis & Bearing Condition Assessment
Old engine oil provides valuable information about internal wear.
We analyze:
- Presence of metal particles
- Oil contamination
- Signs of abnormal friction or overheating
Special attention is given to connecting rod bearings, a known weak point in many used engines. Any abnormal findings result in rejection.
Step 8: Final Quality Approval & Warranty Eligibility
Only engines that pass all inspection stages are approved for sale.
At this stage:
- The engine is validated as mechanically sound
- It becomes eligible for warranty
- It is prepared for secure transport and delivery
Engines that do not meet our standards are never sold.
Why This Process Matters for the Customer
This inspection process means:
- Lower risk of failure after installation
- Fewer unexpected costs
- Confidence for both customer and installer
- A used engine that can be installed with peace of mind
In short, it turns a used engine into a reliable replacement solution.
Our Role: More Than Just Selling Engines
At Auketra, this is our job:
- To inspect
- To verify
- To reject what is not reliable
- To deliver engines we trust ourselves
We help customers make the right technical choice, not a risky one.
Conclusion: Transparency Creates Trust
Anyone can sell a used engine.
What matters is how that engine has been inspected.
By applying a strict, professional inspection process, Auketra ensures that every engine sold meets quality, reliability, and warranty standards.
At Auketra, a used engine is never just a used engine—it is a tested, verified, and approved mechanical solution.
