4 Car Oil Leak Causes and Solutions

A significant number of car oil leaks are caused by deteriorated engine gaskets, oil pan leaks, leaking oil seals, or faulty ties. Crawl under the vehicle to inspect the oil pan seals. While you are at it, double-check the oil pan drain plug. After that, inspect the timing cover seal and valve cover gaskets.

Yes, it is easier to simply disregard the little puddle of oil that has formed under your engine. Alternatively, pretend that the burnt oil smell isn’t emanating from your car.

Is there blue smoke coming from the tailpipe? It could be a serious problem that must not be overlooked. It is not necessarily mandatory to consult a professional mechanic to determine the source of engine oil leaks. A bit of hunting will show a lot, but don’t put it off too long or it will ruin your engine.

What Does It Indicate When Your Car Leaks Oil?

Unchecked leaks may get on rubber hoses or seals, causing them to degrade unexpectedly. Leaking oil will leave hideous streaks on your driveway and pose an environmental risk.

Worse is that engine oil spills pose a fire hazard in the engine compartment that may result in catastrophic engine failure during the worst possible moment, not that there is such a thing as a good time for devastating engine failure. As a measure, repairing oil leaks should be your top priority.

You should monitor the oil dipstick to keep an up-to-date analysis of the condition of the engine as a measure of monitoring oil leaks. You are losing oil if the volume decreases over a short period of time.

Check to see if there is any blue smoke emanating from the tailpipe when driving. Blue smoke indicates the oil is possibly flowing into the engine. Take a whiff after a drive to check for a burning gasoline smell. This may indicate that oil is dripping into hot engine parts.

Finally, look for classic oil stains or puddles under the engine compartment, especially if it has been sitting overnight. If you see a puddle under the engine, take a closer look.

If the substance is red, it is most likely transmission fluid. Coolant is the culprit if the liquid is green or orange and has a delicious odor. An engine oil leak would be indicated by brown fluid.

Why Do Engine Oil Spills Occur?

Degraded piston gaskets, oil pan spills, oil seals, and faulty contacts account for the vast majority of leaks. Examine the oil pan seals from under the engine.

Check the oil pan drain plug when you’re there. Next, inspect the valve cover gaskets and the timing cover seal. Problems here will necessitate substantial and costly repairs.

Don’t be alarmed! You should still attempt to repair oil spills on your own first. It’s not difficult. Here are a few possibilities:

The Oil Filter

Oil filters degrade, become misaligned, or become loose. Any vehicle models have external leaking sections in the filtration system, such as the filter. Whether you do it yourself or get it done by a technician, the filter should be replaced any time you change the oil and properly fitted.

The Oil Drain Plug

A drain plug is located at the base of the oil pan and is available from the underside of the vehicle. A worn-out thread, misaligned threads, or a loose oil drain plug are also common causes of oil leaks. It’s easy to find and there’ll be fresh oil around the plug and on the side where it drips.

The Oil Filler Cap

Oil does not just dribble off. When your filler cap, which covers where you put oil into the engine, is missing, loose, or damaged, engine pressure can cause oil to spill out while the automobile is moving.

The Gasket for the Valve

The gasket is the most prevalent trigger to oil leaks, particularly in older automobiles or those that are driven heavily and have high mileage.

The gasket is a metal seal that connects the head of the engine to other metal parts of the engine, such as the block and the head(s) or the engine block and the oil pan.

The strain builds up over time as sludge (oil that melts down over time due to extended temperature exposure) builds up, causing leaks and defects in the gasket seal.

Minor to serious leakage can occur when the oil pan on the underside is damaged. This can happen when you drive over road debris, big rocks while off-roading, or even inadvertently touch an animal when driving. All of these will dent the oil pan, causing the seal or oil drain plug to fail.

Repairing an Oil Leak at Home

Using a stop leak additive like No Leak Engine Oil Stop Leak is the most cost-effective and fastest way to start repairing oil leaks yourself. No Leak softens and conditions rubber seals once inside your vehicle, safely stopping and preventing automotive leaks.

It works well when engine oil leaks are first discovered, but it can also be used on leaks that have been there for a long time.                          

Any leak, but particularly an engine oil leak, should be handled right away. Understanding what causes engine oil leaks will help you in determining where to look and how to initiate the repair process.

Don’t dismiss it or think it will go out on its own. Be positive in your approach. Protect and maintain the performance of your car so you can keep it on the road where it belongs.

Pro Tip: What is the most effective way to keep car maintenance prices low? Take care of an oil spill as soon as you notice it!

How Much Would a Car Repair Cost if it is Leaking Oil?

An oil filter, a cracked filler cap, or a faulty drain plug are all minor repairs that shouldn’t cost more than $100 at the nearest car parts shop. It becomes more expensive after that.

The cost of repairing a broken oil pan will exceed $1,000, including parts and labor. It is dependent on the type of seal for a degraded gasket. If the head gasket is blown, it can take several hours or days to replace, costing up to $2,000.

Then there’s the broken engine block, which no one cares to know about. To repair a broken engine block (if one is possible), the estimated expense is between $2,500 and $3,000.

If it is determined that a repair is not feasible, the only alternative is to rebuild the engine. This will result in a $4,000 to $5,000 maintenance bill for a standard engine. A luxury or performance engine will cost up to $10,000.
