Car Leaking Oil After Oil Change: What to Do and Why It Happens
Hey Readers,
If you’re reading this article, you’re probably experiencing a frustrating situation: your car is leaking oil after an oil change. While it’s a common problem, it’s important to address it promptly to prevent further damage and potential safety hazards. In this article, we’ll delve into the various reasons why your car may be leaking oil after an oil change and provide you with steps you can take to resolve the issue.
1. Improperly Tightened Drain Plug
The drain plug is the most common source of oil leaks after an oil change. If it’s not properly tightened, it can allow oil to seep out. Tighten the drain plug according to the specified torque using the owner’s manual or a Haynes repair manual.
2. Damaged Oil Filter
The oil filter can also be a source of leaks if it’s damaged or not properly installed. Ensure that the new oil filter is the correct size and type for your vehicle and that it’s properly hand-tightened before using a wrench to further tighten it.
3. Loose Oil Pan
The oil pan, which holds the oil in the engine, can also develop leaks if its bolts are loose. Tighten the oil pan bolts following the specified torque and sequence outlined in the repair manual.
4. Failed Oil Pan Gasket
The oil pan gasket creates a seal between the oil pan and the engine block. If the gasket fails, oil can leak out. Replacing the oil pan gasket requires removing the oil pan, so it’s a more extensive repair than tightening bolts.
Table: Car Leaking Oil After Oil Change Diagnosis Table
| Leak Location | Possible Causes | Diagnosis |
|---|---|---|
| Drain Plug | Improperly tightened drain plug | Tighten drain plug to specified torque |
| Oil Filter | Damaged or improperly installed oil filter | Replace oil filter with correct size and type |
| Oil Pan | Loose oil pan bolts | Tighten oil pan bolts to specified torque |
| Oil Pan Gasket | Failed oil pan gasket | Replace oil pan gasket |
5. Damaged or Cracked Parts
In rare cases, other engine components, such as the oil cooler or lines, can become damaged or cracked, leading to oil leaks. These repairs may require specialized knowledge and tools.
What to Do If Your Car Is Leaking Oil After an Oil Change
- Park your car on a level surface and engage the parking brake.
