Where is the oil leak on a timing cover?
The timing cover is a notorious leak location on many vehicles due to the timing cover’s large size, awkward shape, and multiple joints that need to be sealed. On top of that, your timing cover will also have an oil seal where your harmonic balancer is attached to the front of your crankshaft.
What are the symptoms of a bad crankshaft seal?
Oil leaks Oil leaks are the most common symptom of a problem with the crankshaft seal. If the crankshaft seal dries out, cracks, or breaks, it can cause an oil leak. Small leaks can cause oil to accumulate on the undersides of the engine, while larger ones may produce a drip of oil from the front of the engine.
Where is the oil seal on a crankshaft?
Average rating from 1,197 customers who received a Oil/Fluid Leak Inspection. The crankshaft seal is the seal located on the front of the engine that seals the end of the crankshaft with the timing cover. Most crankshaft seals are made of rubber and metal and are round in shape.
Can a crankcase oil additive stop a leak?
Crankcase oil additives can sometimes help slow a leak by causing aged gaskets and seals to swell, but no additive will stop a major leak or repair a broken gasket or worn seal. Sooner or later you will have to replace the leaky gasket or seal.

What to do if your front crankshaft seal is leaking?
You are looking for engine oil that is leaking between the balancer and the timing chain cover or front seal housing. If a leak is detected check above the seal to make sure oil is not leaking from a higher point and making it look like the seal is leaking.
Why is oil leaking from the front of my car?
In some cases the timing cover may be cracked, especially if it is manufactured out of plastic. If you notice that oil is leaking from the center of the motor, near the front, it may be due to a faulty timing cover or timing cover gasket.
What happens when a timing cover is damaged?
When a timing cover becomes damaged and does not properly seal with the engine block, dirt and debris can enter the engine; especially in critical areas like the crankshaft or camshaft. When this happens, the engine may run rough.
How can I tell if my timing chain is bad?
Once the belts have been removed, start the engine. Place the probe of the stethoscope on the top or side of the timing chain cover. If you hear a rattling or scraping sound, with no other noise being emitted from the engine, it indicates a bad timing chain. Do not run the engine excessively long with the belts off.
What do you do when your timing chain rattles?
Don an automotive stethoscope and place the probe on the top or side of the timing chain cover. If you hear a rattle, metal to metal slapping or scraping coming from inside the cover, it indicates a timing chain noise.
What causes a delay in the timing chain?
These filters have an anti-drain-back valve which stops oil from leaving the filter after the engine is turned off. But if this valve goes bad or malfunctions, the oil flow will get delayed when you go to start the engine again. This causes a delay in the lubrication for the engine, including the timing chain.
What causes a timing cover leak?
The timing cover has a gasket that allows the cover to be securely attached to the engine block. Over time and due to exposure to heat, dirt, road grime, and more, the gasket can often become cracked or wear out. This will reduce the tightness of the timing cover and may result in oil escaping the engine and leaking onto the ground.
What is a timing cover leak?
A timing cover is designed to control engine oil on timing chain style of engines. This cover is sealed to the engine block using a gasket which can leak due to age and heat. This kind of leak can be difficult to find so sometimes it’s best to clean the engine first.
Is your timing cover gasket failing?
The gasket is located under the timing cover housing, and seals the timing components from any outside debris. Signs that the timing cover gasket is failing may include an oil leak beneath the vehicle, or premature damage to timing components.
