Problem Statement

Learn how to diagnose and fix engine ticking noise in Toyota Corolla E170 (2013-2019). Step-by-step guide with diagnostic procedures and repair instructions.

Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening the oil cap or draining oil.

Symptoms

•Ticking noise from the engine, especially noticeable during idle or acceleration
•Decreased engine performance or power loss
•Check engine light illuminated
•Poor fuel economy
•Possible engine vibration or rough idling

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored trouble codes.
2
Check engine oil level and condition, ensuring it is at the proper level and not contaminated.
3
Listen for the noise location by using a mechanic's stethoscope or a long screwdriver to pinpoint the source of the ticking.
4
Inspect the valve cover and timing chain/belt for any visible signs of wear or damage, including loose components.
5
Check for exhaust leaks at the manifold and throughout the exhaust system, as these can sometimes produce ticking sounds.
6
Perform a compression test to check for any potential internal engine issues, such as worn piston rings or valves.

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

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Oil Change (if oil condition is poor)

Drain Engine Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow oil to fully drain.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new oil filter with a bit of new oil and install it.
Refill Engine Oil:
- Reinstall the drain plug and torque it to the manufacturer's specification (usually around 30 ft-lbs).
- Fill the engine with the appropriate grade of oil (typically 0W-20 for this model) using a funnel.

3. Valve Adjustment (if necessary)

Remove Valve Cover:
- Unbolt the valve cover using a socket set and carefully lift it off.
Check Valve Clearances:
- Use a feeler gauge to measure the clearance between the rocker arms and the valve stems.
- Adjust the clearance as needed by replacing shims or adjusting the rocker arms per manufacturer specifications.
Reinstall Valve Cover:
- Clean the mating surfaces and apply a new gasket or RTV sealant.
- Torque bolts to the proper specification (typically around 7-9 ft-lbs).

4. Timing Chain/Belt Inspection (if applicable)

Inspect Timing Components:
- Remove any necessary covers to access the timing chain or belt.
- Check for wear on the chain/belt, tensioner, and guides.
- Replace any worn components as needed, following manufacturer specifications.

Tools Required:

OBD-II scanner
Socket set
Oil filter wrench
Torque wrench
Feelers gauges
Mechanic's stethoscope or long screwdriver

Parts Required:

Engine oil (0W-20)
Oil filter
Valve cover gasket (if needed)
Timing chain/belt components (if needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Disconnect the battery before working on electrical systems.
Allow the engine to cool before opening the oil cap or draining oil.
