Problem Statement

Learn how to diagnose and fix excessive oil consumption in Honda Accord 9th Generation (2013-2017). Step-by-step guide with symptoms and solutions.

Affected Component

Engine

Estimated Time

4-8 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow engine to cool before opening the oil drain plug and removing the cylinder head.

Symptoms

•Check engine light illuminated
•Engine oil warning light on the dashboard
•Excessive smoke from the exhaust
•Unusual engine noises (ticking or knocking)
•Reduced engine performance
•Frequent need for oil top-ups

Diagnostic Steps

1
Check the engine oil level using the dipstick to determine if oil consumption is evident.
2
Inspect for oil leaks around the engine, under the vehicle, and on the ground.
3
Perform a compression test on each cylinder to assess the condition of piston rings.
4
Conduct a leak-down test to pinpoint where oil is escaping.
5
Check the condition of the PCV (Positive Crankcase Ventilation) valve and system for blockages.
6
Inspect the valve seals for wear or damage, which can lead to oil entering the combustion chamber.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Socket set
•Oil filter wrench
•Torque wrench
•Compression tester
•Leak-down tester
•Valve spring compressor

Parts Required

•Engine oil (5W-20 synthetic)

Solution

1. Preparation

Gather all necessary tools and components.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down before starting any work.

2. Change Engine Oil and Filter

Sub-steps:
- Use a socket set to remove the oil drain plug and drain the old oil into a pan.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and torque it to manufacturer specifications (typically 30 ft-lbs).
- Fill the engine with new oil (5W-20 synthetic recommended), checking the level with the dipstick.

3. Inspect and Replace Piston Rings (if necessary)

Sub-steps:
- Remove the engine cover and disconnect any components obstructing access to the cylinder head.
- Remove the cylinder head bolts and carefully lift the cylinder head off.
- Remove the pistons from the engine block by removing the connecting rod bolts.
- Replace the piston rings with new rings and ensure they are properly seated.
- Reassemble in reverse order, ensuring all components are torqued to specifications.

4. Replace Valve Seals (if necessary)

Sub-steps:
- Remove the cylinder head as described in the previous step.
- Use a valve spring compressor to remove the springs from the valves.
- Replace the old valve seals with new ones.
- Reassemble the cylinder head and reconnect all removed components.

5. Inspect and Clean PCV System

Sub-steps:
- Locate the PCV valve, usually near the intake manifold.
- Remove the PCV valve and inspect it for clogs or damage.
- Clean or replace the valve as necessary.
- Ensure all hoses are clear and free of obstructions.
