The front and rear main seals will cause a significant oil leak or even the valve covers. I pressure washed mine really well then kept a eye on the leaks and it was a front main seal not easy to replace because you have to remove all the intercoolers and radiator then u have to seat the seal perfectly or it will leak again

SOURCE: Oil Leaks

I did an engine swap because of a rod knock and when I removed the power steering pump the seal was upset and would not seal again. I found a guy on the internet who had a kit for under $75 shipping included (sorry can't remember sight name). This kit comes with a new improved two lip seal, couple o-rings, gasket, home made tools, and a video showing how to install the new seals. I installed the kit and it fixed the leak in about 3 hours. The dodge dealer wants $1100.00 for a rebuilt vacumme pump. Do a google for power steering leak.This is a very common problem even for a pump that has not been removed.

Where is the most common place for a oil leak a BMW 323i

in my opinion the #1 most common place is from the oil filter housing. Stand at the front of the engine bay, look at the right side of the engine block under the intake manifold. If the block is oily, wet, then that's the culprit. There's a $5 oil seal that dries out and can end up causing oil drops on your driveway. The labor for this repair can be several hundred bucks. it takes about 3-4 hours. Other common areas are the valve cover gasket in cars over 100K miles. If you smell oil burning inside the car, when you start it up in the morning, it's likely leaking here and getting on the exhaust manifold where it burns off..
Next place to look is the high pressure hose form the vanos to the oil filter housing. It's a 8" hose with banjo fittings. Over the years they can start to leak a little. Lastly the oil pan gasket can start to leak on cars with high mileage. My 98 323is has had all four over the years. It has almost 200K on it. I've done the oil filter housing gasket and some day will do the rest
The oil filter gasket is the one that leaks the most. It's not hard to do yourself if you are mechanically. There might be youtube videos to help. Good luck.

What are comon places for oil leaks on a 1994 v6 camaro

Some models have an adapter that goes between the oil filter and the block. The oil pressure sending unit is nearby also.
You may have to spray clean the area to find the leak.

I have a 1999 toyota camry and it just resently started leaking engine oil. It is not leaking around the filter or the oil plug. It only leaks when the car is running. Where is the next most common place...

the most common place for a leak, especially when the engine running, is the rocker cover gasket on the top of the engine. other places include the crankshaft and camshaft oil seals, the sump gasket, and as you have already said, the oil filter and sump plug.
it is a lot easier to spot a leak if you pressure clean the engine first.
that way it is much easier to see any fresh oil and where it is coming from

Every 400 miles leaks half quart of oil

Oil leaks can come from many places. The most common are the Valve Cover Gaskets, around the Oil Pan and the Rear Main Seal of the engine. You might also want to check that your oil filter is not on crooked. Sometimes this can happen when you go to a Jiffy Lube or quick oil change service place. Even just a little crooked can result in a leak.

If you cannot follow a leak to it's source, then it is likely that your car being a 1991 is just getting old and burning more oil. You can help extend your cars life by giving it a thorough tune up and making sure to take extra good car of it. You can also start putting a thicker grade of oil in it, such as 50 weight instead of 20 or 30 weight (which are the most common).

Severe oil leak happen while driving. Engine still runs but can't locate where leak is coming from. Any Ideas or solutions beside paying 100s of dollars.

Common area for oil leaks would be from the oil filter, oil line to the cooler attached to the radiator and the other place that is most common would be a faulty oil pressure sending unit.
When the oil pressure sending unit goes bad, oil will leak from the unit. It's made of a metal fitting and plastic top and the plastic will tend to crack after a few long years from the heat making them brittle.
Inspect your oil pressure sending unit and replace if any sign of oil, You can pick up the unit at Auto Zone and can give you the step by step instructions to get the job done with common tools. They would also be glad to help you find where the leak is coming from free of charge.
Thank you for using fixya and if it's your transmission that is leaking, don't drive it if the level is low and take note transmission fluid is flammable and will catch fire from the heat of the exhaust.

Oil cooler lines leaking. Motor losing all the oil within 10 minutes.

Inspect where the oil is leaking from the oil cooler line, it's common for the oil to leak from the remote oil cooler line adapter bolt on the engine block. You can remove the two bolts one at a time and place a oil drain plug washer with some RTV silicon to ensure that it will not leak.

The other common place for the oil line to leak is from where the rubber lines mate to the aluminum line from the remote oil filter line adapter. This is also a simple fix but you're going to need a drumlin tool cut off the old compression clamp that was press fit. Cut off the old compression fitting ring, use cation that you only cut off the ring and replace it with a new compression clamp. Make sure you use compression clamps and not a hose clamp.

This is the best way to fix the oil leak from the adapter line to the rubber hose line, to replace the whole line with the new adapter is expensive and i believe your have to disconnect the engine mount to raise the engine to clear enough room to install the new line along the frame.

Good luck and don't use any engine oil stop leak, it will damage your oil pressure relieve valve and that's one extra thing you don't need to replace.

1998 olds Aurora i have an oil leak, is it common

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.

I dont know where the oil pump is on my 89 toyota

On a 22RE the oil pump is on the timing cover behind the crank pulley/harmonic balancer,it has the crank timing pointer built onto it,generally they don't leak around the pump seal but as Monster80 pointed out they leak from the front main seal wich is installed on the front of the oil pump,pretty common for the 22R/RE to leak around the timing cover gaskets or out the bolt holes on the timing cover also,usually due to uneven tourqe on the bolts,to check the front main seal you need to look at the the crank from the underside right after you've shut the motor down,if the seals bad you'll see oil starting to form a drop on the backside of the pulley or the front of the oil pump housing.
