How to Fix a EZGO Golf Cart Leaking Oil (STEPS)

EZGO Golf Cart leaking oil

Why is my EZGO golf cart leaking oil?

The EZGO golf cart might leak oil because of a crack in the freez plug, a worn-out out filter, or damaged valve gasket.

  • Hole in the freeze plug: A hole or a crack in the freeze plug.
  • Worn-out Oil filter: There can be a worn-out oil filter (due to extensive use of the cart), a misfit one or even one with an improper alignment.
  • Valve Gasket problem: This is one of the most pestering as well as frequently encountered problems that is associated with oil leaks. These are found in relatively worn out vehicles and those which have run for longer hours.
  • Injured oil pan: Travelling over rough terrain can cause some injuries or dent to the oil pan, oil seal or drain plug underneath the cart. This can be a source of oil leaks too.

All the EZGO golf cart engines are nine horsepower units with twin-cylinder systems. They require oil with a weight specification of 10W-30 to about 10W-40. It is very important that you put the right kind of oil into your system to ensure smooth function and longevity of the engine.

Usually you will notice that most of the oil leaks around the clutch side of the motor, around the heads, sparing the main seal area, the transmission pane.

We all know that oil breaks down with passing time into a sludge-like substance because of continuous exposure to high fluctuation of high temperature and pressure that gets deposited in the gasket joint. It is this mounting pressure that causes the gasket joints to balk under pressure and start leaking oil.


Robin 295 engine leaking oil problem

Your EZGO Robin 295 cc engine might be leaking oil for the following reasons:

  • Issue with the valve cover gasket: You will probably want to check the gasket for proper sealing, alignment and injuries.
  • If the above step is clear, then do a compression test on the gasket.
  • Check the valve adjustment, if it is loose.
  • Check if you have a missing O- ring.
  • Do the inspection on the spark plugs and carb, and check if they are firing alright and clean to boot.
  • Sometimes, the engine near the timing belt can start leaking too. In such a case, instead of bending down continuously and straining your back, it will be better to just take out the engine on a bench and fix it.
  • After you have fixed it as needed, don’t forget to check the head gasket for leaks (if any).
  • Pro tip- you must keep the engine with the dripping area facing upwards, so that it is easier to work. Also, don’t forget to inspect other parts of the engine for potential leaks.


EZGO TXT PDS leaking oil problem

The EZGO TXT PDS might leak oil at the place where the rear differential is enjoined to the motor. To fix this problem, you have to first cool and clean the engine well. However, cleaning will not always address the problem from the root. This negligence, if not addressed, will snowball into graver troubles. For example, the oil from the rear-end may be let into the motor, and it may catch fire or choke the engine too.

Sometimes, you may see that the O-ring for the input shaft might have been dysfunctioning or the freeze plug towards the side of the trans-axle might be leaky. These can cause the TXT PDS to leak oil profusely and come out of the car and stain the entire driveway.


EZGO RXV leaking oil problem

An EZGO RXV can start leaking due to a number of reasons. Some of these problems and their solutions are listed below.

But before you try to fix anything, you must make sure from where the leak is coming from. To do this, you might want to rev up the engine for three or four minutes just to bring up the optimum temperature. Then shut off the engine and identify the source of the leak.

  1. Leaky cylinder gasket: The cylinder gasket can get damaged due to wear and tear and faulty sealing. Make sure you keep it clean to avoid residue build up.
  2. Leaky crank seal: Cranky seal or faulty alignment of it will lead to oil leaks. You must always check with a wrench for any loose bolts.
  3. Overfilling problem: Golfers overwhelmingly agree that the EZGO RXV is notorious for its overfilling problem associated with a faulty dip stick. What happens is that when the car is jacked up, the meter reading fails to show the actual level of fullness. It gets tilted instead and makes you overfill your tank. As a result, oil spills out.


EZGO marathon leaking oil problem:

The EZGO Marathon can leak oil because of a fault in the breather shaft of the crank case. To fix it, you will have to drain the oil and close off the carb with an anti-leak plastic. You can remove the clutch and get to the bolts to fix it. Change the sealing if necessary.


How to fix EZGO electric golf cart leaking oil problem:

Most of the leaking issues on the EZGO Electric golf cart are related to worn out gaskets. You must keep your gasket and its sealing prim and clean.

However, some users also complain about the O ring malfunctioning. In such a situation, you must change the o ring by taking out the input shaft. This can be done with the help of a kit containing new bearings, o ring etc. that is easily available in the market.

These days, brands have come up with oil slingers that can prevent oil leakages from occurring. You can use one of those for additional safety.


EZGO rear differential leaking oil problem:

To fix an EZGO rear differential oil leak problem follow these simple steps:

  • Wrench apart the oil pan at the bottom of the cart.
  • Carefully pour out the oil into a bigger container.
  • Clean the old sealant grease off the differential and the pan.
  • Put a gasket sealant on the pan and change it.
  • Allow it to dry overnight and finally add oil to it.
  • Take out the side plug and replace it with a standard oil. Make sure it meets the specifications set by the manufacturer.
  • After you are done, carefully replace the plug and ride the car for some distance.
  • Check for any oil drip. Ideally, there should be none by now.


EZGO rear end oil leaking problem:

You should jack up your cart and detect the source of the oil leak. Oil can leak out from a variety of sources like the input shaft, a crack or a hole in the freeze plug or even a non-functioning oil seal. 

Oil can also leak out from the main gasket or from an injured bottom pan. You must check these areas and change the leaking parts, if necessary.

It is also important to keep the bolts on the triangular oil filter area tightly screwed up to prevent leakages.


Why is there oil in EZGO air box?

Oil can seep in and appear inside the EZGO air box because of reasons like a particularly steep climb over a small hill or a drive over a rough terrain. But the good news is that you can easily fix it.

Since prevention is better than cure, you must try to take precaution before it happens. One of the easiest and inexpensive ways is to use a filtering fabric in the mouth of the crank case breather tube. You can use a material like nylon that will allow the vapours to pass while effectively preventing the oil to spill out.

There are some oil sealing fluids available in the market which seem to help the EZGO leaking problem.

For the 295 or the 350cc EZGO buggy engines, you must remain cautious of not overfilling your tank when you take it out to feed it. This is a very common phenomenon when you try to fill your engine fully while it is in a lifted up position. This is due to the fact that when it is lifted up, the oil level is inclined to such a position that the meter on the dipstick which shows ‘full’ gets messed up, allowing you to keep on pouring more oil into the tank.

In this position, the crank case breather dips into the oil level, the oil gets pushed up through the hose, thereby letting in oil into the air box. As a consequence of this, after riding for a few miles, your engine will start to smoke vigorously. But you can prevent this too.

In such a situation, you have to drain the engine of all the oil, wash it with a power hose, dry and then fill it with a precise amount of 1.5 quarts oil. This is the ideal amount that will allow the engine to self-lubricate and keep running. Then you can take a marker and mark a new level of full on the dipstick.

This new, adjusted mark will allow you to stop overfilling and avoid leaky tanks every time.
