I’m having great difficulty performing a vale seal replacement on my EZGO golf cart. Can anyone guide me on the steps to do this?
Response
I would suggest you replace the valve seals and also check the oil rings.

Symptoms
- Golf cart emits white or grey smoke upon startup
- Golf cart continues to smoke even after warming up
- Oil level drops faster than usual
Possible Causes
- Worn valve seals
- Damaged oil rings
- Over-revving the engine
Solutions that Worked
1. Replace Valve Seals
What I Did:
Replaced the valve seals as they were hard and brittle.
Outcome:
The golf cart stopped emitting smoke.
Personal Experience:
After replacing the valve seals, the issue was resolved.
Estimated Cost:
$50-$100
Time Needed:
60-120 minutes
Steps:
- Disconnect the battery.
- Remove the valve cover using a socket wrench.
- Use a valve spring compressor to compress the valve springs.
- Carefully remove the old valve seals with needle-nose pliers.
- Clean the valve stem area.
- Lubricate and install the new valve seals.
- Reassemble and reconnect the battery.
Expert Tip:
Always inspect the condition of the existing valve seals before replacing them. If they are hard and brittle, new seals are likely to make a difference. Also, consider using a magnetic tool to keep track of any small parts like screws or bolts.
2. Check Oil Rings
What I Did:
Checked the condition of the oil rings.
Outcome:
Found that the oil rings were damaged.
Personal Experience:
After replacing the oil rings, the smoke issue was resolved.
Estimated Cost:
$30-$60
Time Needed:
45-90 minutes
Steps:
- Remove the spark plug.
- Use a socket wrench to remove the cylinder head.
- Take out the piston and inspect the oil rings.
- Replace the damaged oil rings.
- Reassemble the piston and cylinder head.
- Reinstall the spark plug.
Expert Tip:
If you notice continuous smoke even after the engine has warmed up, it’s more likely to be an issue with the rings rather than the valve seals. Always use quality replacement parts to ensure longevity.
3. Compressed Air Method
What I Did:
Used compressed air to hold the valves closed while replacing the seals.
Outcome:
Successfully replaced the valve seals without any issues.
Personal Experience:
Used compressed air and the process went smoothly.
Estimated Cost:
$0
Time Needed:
30-60 minutes
Steps:
- Disconnect the battery.
- Remove the valve cover.
- Use compressed air to hold the valves closed.
- Remove the old valve seals with needle-nose pliers.
- Install the new valve seals.
- Reassemble and reconnect the battery.
Expert Tip:
Be cautious with the valve keepers, especially if it has the “2 piece style,” as they can fall into the oil return holes of the head and into the engine. A magnetic retrieval tool can be a lifesaver in such situations.
Safety Tips
- Valve Seal Material: Not all valve seals are made the same. Some are made of rubber while others are made of polyacrylate or silicone. Make sure to choose the right material for your specific golf cart model.
- Engine Oil: Sometimes, the type of engine oil you use can contribute to smoking issues. Consider switching to a high-mileage oil designed to rejuvenate old seals.
- Valve Seal Tools: Specialized valve seal pliers can make the job much easier and are worth the investment if you plan on doing this more than once.
