Check if the Engine is Washed
If you find that your Audi engine is washed while purchasing, there is a 90% chance that the seller is trying to hide oil leaks or any major problems. Thus do check whether the engine is washed, as it can hide a lot of significant details.
Check Whether the Bolts are Unscrewed
It can be immediately said whether the Audi engine was in an overhaul stage or it was in the car its entire service life. If you find bolts unscrewed, you will notice traces of the key on the edges. Moreover, if bolts are unscrewed, it also indicates that there is an issue with the cylinder head valve or any oversealing of oil seals.
Inspecting Cylinder Head Valve Covers
Before you purchase an Audi engine, make sure you have a careful look at the fasteners on the front cover. Through this, you will be able to assess the condition of the bolts. Make sure factory sealants are put on them, thereby ensuring that it is in perfect condition.
Check the Oil Condition
Take the oil filler cap off and give it a thorough inspection. No carbon buildup, oil stains, or dark metallic deposits are allowed within. In order to check for the presence of the same carbon deposits on the engine’s internal components, it is also required to look into the throat itself. The buyer should take note of the interior’s brightness and cleanliness because this indicates that the owner has only used high-quality engine oil in the engine.
Inspecting the Pulleys and Gears
Before you purchase a used engine, make sure you properly check the pulleys and have a thorough analysis of them. With respect to the rule, the average mileage for timing belts is 60k and about 150k for the chain. This also helps to assess the condition of the related parts. If the engine goes through serious mileage, it leads to the formation of steps on the pulleys. In the case of steps, the metal during the operation of the vehicle slips, thereby causing a distinct trace on edge.
Check the Spark Plugs of the Audi Engine
Checking the spark plugs is a crucial step when it comes to the inspection of a used Audi engine. The electrical lines are severed from the contact head and unscrewed with a specific candle wrench. Examine the candle’s insulator after unscrewing it. The presence of a yellow-brown plaque may indicate that the engine was run on poor-quality fuel. If you notice small carbon deposits on either side of the vehicle, it is not an issue, as it can be resolved by simply replacing the plugs. However, if you notice a strong carbon deposit, it indicates a major problem with your used Audi engine.
Use an Endoscope
We advise utilizing an endoscope to check the motor’s functionality. A camera and a spotlight are attached to the extendable probe that makes up this tool. The endoscope is inserted into the hole created by unscrewing the candles, and it is incredibly easy to use. The camera will make it feasible to inspect the cylinders’ overall condition and determine whether there are any issues present.
Check for Cylinder Lekas
To check whether your used Audi engine is in good condition, try to first unscrew the spark plugs from that of the cylinder head. Then check when the compressor is pumping air; the engines should not lose more than 10% of the air. If you find anything beyond this, make sure to avoid such engines.
Which Used Audi Engines Should You Prefer?
Since you now know how to pick the best used Audi engine, let us understand which are the most reliable used Audi engines to be used. If you are planning to go for a used engine, try to purchase either an EA113 or a Gen 3 EA888 engine. These are quite versatile engines and are known to handle a considerable load.
