2. Compressor seal is worn

In addition to the oil seal, a worn compressor seal can also cause engine oil to leak. Friction between components is the main reason the compressor seal wears out easily. Additionally, the age of use can also cause this component to wear out.

3. Damaged cover bolt

The next cause can be due to a damaged cover bolt. This condition can cause the bolt to be too tight, tilted, rusty, or too loose.

4. Packing (oil pan) has hardened

The next cause of engine oil leaks can be due to the packing that has hardened due to age. As is known, this component functions to prevent oil leaks. This component can also be referred to as a barrier between the cylinder block and the cylinder head. If this component is damaged, it can be ensured that the engine oil will decrease and leak into the engine components.

How to Fix Leaking Oil

When you experience engine oil leaks, you don't need to panic, as below will explain the correct ways to fix it. Here are the complete methods.

5. Use seal tape

The next way is to use seal tape to prevent engine oil leaks. This method is quite economical; you just need to pry off the damaged oil seal and then install the seal tape. Before installing it, you need to ensure the oil volume is at the standard level. If not, you can refill it.

6. Use glue

The next way is to use glue to address oil leaks. The method is quite simple; use seal tape to wrap the threads on the bolts. Then use sealing glue on the engine valve to prevent oil leaks. You can also use metal glue on the leaking part.

Cost of Repairing Leaking Engine Oil

The cost for repairing leaking engine oil is estimated to be around Rp150,000 to Rp450,000. This price applies to Japanese manufactured cars, while for European manufacturers, the price is significantly higher.

If the damage to your car is considered minor, you only need to use sealant to prevent oil leaks. This product is usually sold at prices starting from Rp300,000 to Rp500,000.
