I replaced valve cover gaskets and camshaft seal and I still have small leak on driveway. oil pan gasket isn't leaking. any other common places the leak may be coming from?

Oil leakage in the timing compartment of an engine can be caused by a variety of factors. Some common causes include:

1. Worn or damaged valve cover gasket: The valve cover gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
2. Worn or damaged timing chain cover gasket: The timing chain cover gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
3. Worn or damaged oil pan gasket: The oil pan gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
4. Worn or damaged crankshaft seal: The crankshaft seal is responsible for preventing oil from leaking out of the timing compartment. If this seal becomes worn or damaged, oil can leak out of the compartment.
5. Worn or damaged camshaft seal: The camshaft seal is responsible for preventing oil from leaking out of the timing compartment. If this seal becomes worn or damaged, oil can leak out of the compartment.
6. Worn or damaged Timing chain tensioner: Timing chain tensioner is responsible for maintaining proper tension on the timing chain. If this tensioner becomes worn or damaged, oil can leak out of the compartment.
7. Worn or damaged Timing Chain: Timing chain is responsible for maintaining proper timing of the engine. If the timing chain becomes worn or damaged, it can cause oil leakage in the timing compartment.
8. Low oil level: If the oil level in the engine is low, it can cause oil to leak out of the timing compartment.

It's important to address oil leaks as soon as possible, as they can lead to serious engine damage if left unchecked. To determine the exact cause of oil leakage, it's best to consult with a mechanic or take the car to the service center.

I always buy a service manual from advance or some parts supplier for every vehicle I own, that way the manual tells me how the parts are mounted to the motor and their location to the rest of the motor.
I am not sure where the starter is located on a Pontiac G6 but look above it if you have to use a flashlight, if your oil filter is near it, make sure it is tight and not loose.
Sometimes valve pan gaskets leak and run down the side of motor making us believe oil is coming from another place, just start looking and you will find it.

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.

External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.

Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.

Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.

Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

Hello Tina,
The most common ENGINE oil leaks come from a valve cover gasket, a front or rear main engine seal, a timing cover gasket/or seal, oil pan gasket/oil filter/housing/drain plug, or a faulty sensor. If you can't see where it's leaking from the topside, have it hoisted for further inspection.
Good Luck, i hope this helps & thanks for using FixYa.

There are alot of places where oil leaks out. The most common places on this engine are the front and rear crankshaft seals valve cover gaskets and yes, the oil pan.

Since it's not clear whether you mean driver side or passenger side, I will address both.

On the driver side, the most common leak is from the distributor. This can be caused by the distributor shaft exterior o-ring, or it can be caused by the distributor shaft interior bearing seal. To determine which it is, remove the distributor. First detach the spark plug wires, then undo the bolt that holds the distributor to the head, then pull the distributor out of the head. You will see the o-ring on the exterior of the distributor shaft. This is a $0.50 part, so just replace it with a new one as long as you have the distributor out. The bearing seal is on the inside of the distributor. To inspect it, undo the three bolts holding the cap to the distributor body. Pop the rotor off the shaft, the unclip the inside plastic cover. If you see any oil inside the distributor or the distributor cap, this means the seal is leaking and must be replaced. You can get a seal and bearing replacement kit from kbox.ca. Or, you can just buy a new distributor. Note: To get the distributor back in place you must align the shaft correctly with the notch in the camshaft. There is a right way and a wrong way. If the shaft seems to be aligned but does not go in, pull it out and rotate it 180 degrees, then put it back in.

The other possibility on the driver side of the engine is the main seal between the engine and transmission. If this is the case, you would have to either drop the transmission or pull the engine to replace it.

What if the oil is leaking on the passenger side? If it's coming from behind the timing belt cover, there is a camshaft seal and a crankshaft seal, both of which can leak oil. To get to them, you will have to remove all accessory belts and the alternator, remove the exterior crankshaft pulley, remove the engine mount (support the engine) and the timing belt covers, remove the timing belt, then the crankshaft pulley and/or camshaft pulley, whichever is necessary to replace the leaking seal(s).

Where else could oil be leaking from? If it's coming out from near the top of the engine, that's the valve cover gasket. Remove the valve cover and replace the gasket. While you're at it, replace the spark plug tube seals.

If it's coming out from near the bottom of the engine, it could be the oil pan gasket. Remove the oil pan and replace the gasket.

One more possibility for oil leakage: The head gasket. But in this case you would have noticed other symptoms besides just an oil leak.

Good luck! Let us know how it turns out.

Clean all the area and check again; maybe the seal need one new adjust or the oil pan cap too.

Tell us news.

There are common places, you'll just have to look around to see where the leak is:
Around the oil filter and the housing
Around the oil pan and the pan gasket
The oil seal behind the damper pulley
Valve cover gaskets
These are the most common places, leaks can spring up anywhere.

In order from most common to lease:
rear crank seal
valve cover gaskets
oil pan gasket
front crank seal
oil sending unit
head gasket
