How to Repair an Oil Pan Gasket Leak?

2 minutesread

Oil Pan Gasket Leak Repair:

Typically, to repair a leak from the oil pan area, you’ll replace the oil pan or gasket.

It’s important to notice that, on many vehicles, other components must be removed first to achieve access to the oil pan. In some instances, the whole engine must be aloof from the vehicle to reach the pan—so ensure to consult the repair manual for your vehicle before digging in.

The following may be a general outline for oil pan replacement on a vehicle that gives direct access to the pan.


1. Prepare the vehicle:

Make sure the vehicle is parked on a level surface, set the emergency brake, and chock the rear wheels. Then, safely raise and support the car employing a jack and jack stands. Disconnect the negative battery cable.


2. Drain the oil:

Place a container directly under the placement of the oil pan. Remove the drain plug to empty the oil.


3. Unbolt the oil pan:

Locate all of the bolts holding the oil pan to the bottom of the engine block. Then, start removing the bolts one at a time.

It helps to depart some bolts at one end of the pan in place until you’re almost done. That way, you’ll be able to leverage the tip of the pan opposite the bolts to empty the oil and avoid a large number.


4. Remove the oil pan:

Finally, you’ll be able to remove the oil pan. If it’s stubborn, tap on that gently with a dead blow hammer or rubber mallet to urge it free.


5. Remove the old gasket:

Remove the old gasket and punctiliously scrape any remaining material from the engine. Clean the mounting location on the engine with solvent—the area must be completely clean for the new gasket to make a decent seal.


6. Install the new gasket and the oil pan:

After everything is clean, you’ll be able to install the new gasket and the oil pan. Start by placing the gasket on top of the pan. Then, insert a pair of bolts through the pan to carry the gasket in place.

Finally, thread those bolts into the engine by hand.

Once the pan is in place, you’ll be able to thread the rest of the bolts in (also by hand). Next, use a spanner to tighten the bolts to the manufacturer’s specification.

If you’re reusing the old oil pan, reinstall the drain plug and tighten it to specification.


7. Refill the engine with oil:

Carefully remove the jack stands and lower the vehicle. Once you’ve done that, refill the engine with the proper amount of fresh oil.

Reconnect the negative battery cable, then start your engine and carefuly check for leaks.
