Either the filter isn't screwed all way in or there is dirt on the sealing surface that prevents a complete seal - take the filter out and clean everything in sight.

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 causes the oil filter housing to leak - it is above the filter - we replaced the filter but this is on seam about 1/2 inch above the top of the filter


If there is a spacer between the oil filter and the engine block then you would could have a bad seal on it. If its similar to a Honda there will be to hoses going to the spacer. This spacer is called the oil cooler adapter. If this is it. Take oil filter off and the remove the oil cooler nut if there is enough room you won't need to disconnect cooling lines. Pry the Adapter away from the block with screw driver. remove old seal clean surface with clean rag install new seal. Wipe a little oil around the seal just like you would the oil filter. 'Tighten snug, but don't over tighten. Not sure the correct torque for this. Hope this helps you. This similar problem occurred on my 1995 Honda Odyssey.

1994 Ford Crown Victoria with less than 90,000 miles. Vehicle has a serious oil leak. I believe it is coming from the oil filter housing. I am not sure if these mount to the block with a gasket or not. Any...


The filter housing would have an o-ring seal, first step would be make sure it's not the oil filter gasket itself. The pressure internally would spray oil and depending on where exactly the leak is it could be tricky. A can of engine degreaser would go a long way. If the filter was put on too tight or with an old o-ring still stuck on the housing it can be as big a problem as if it's left slightly loose. check the small things first and take your time.

While putting on the hoses one of the hoses connect to the oil filter housing and it moved slightly but enough for oil to leake do i need to replace a gasket or can i turn it back the other way and solve...


there is a rubber seal behind the oil cooler(that is where the hose connects) the best thing would be to remove the oil filter and oil cooler to replace the seal. I would at least remove the oil filter and try to tighten the large nut that holds the oil cooler on and see if that stops the oil leak

Oil filter housing leak


you may have left out the brass ring. Or put an extra one on there. Go back to the auto parts store. Carefully see what parts are included in the oil filter mechanism and replace them. two O-rings a brass ring and then the oil filter. press down on the top cap and tighten the 10mm bolt, that should seal it.

Oil leak from oil filter


There is an "O" ring between the Oil filter housing and the adapter that will leak as well. Remove the oil filter and check inside of the housing for a large nut. Remove the nut and separate the adapter from the housing. Check the "o" ring between them and replace with new "o" ring. That's where mine is leaking and I've read a couple of others that had the same problem. The old ring started out "round" and has, over time, become flat. The new ring should start out with a flatter cross section that will seal better. Good luck! (Easy Fix, but finding the "o" ring may be a challenge. Check for the ring at the Honda Dealer as the Passport is the same basic vehicle.) Do it during the next oil change........
