Bad oil leak around oil filter changed oil and filter still no better
If you got oil coming out when it's running around oil filter. You probably got a oilfilter adapter. You have to remove oil filter(replace) and let oil drop off adapter. After a bit wipe adapter off and you will foind one alan-head bolt in the center or two alan-head bolts. After removing clean, install gasket or a o-ring it could take both. Don't over tighten bolts. Make sure you clean off old oil where oil filter seats
SOURCE: oil leak?
Whoa whoa ... You've said that the car takes 7 quarts of oil. That's 14 pints. Depending on which engine variant is fitted, engine oil capacity is either:
If you've filled the car with 7 quarts of engine oil that's almost twice as much oil as should be in the engine. Did you mean pints when you wrote quarts?
If you've filled it with 7 quarts it's overfull. Way too full. Check your oil dipstick - remove it, wipe it clean and then dip the oil level. At the bottom of the dipstick there is a flattened wider part. The oil level should not be below the bottom of this marker, and nor should it be above it. If the oil level is way above the flattened marker bar - you're overfull and will have to drain some oil out of the engine. An overfilled engine will try and blow oil out from wherever it can as the oil system will over-pressurised.
Ok .. so there's no problem with the engine compression. The crankcase isn't overfilled with oil (the crankcase is known as the oil sump in the UK). There's no oil fouling of the plugs and the car isn't burning oil, just leaking it. There's no misfires or running
If the engine isn't overfilled with oil there may be a problem with a broken/sticking piston ring or piston/cylinder. That high oil loss you mention seems severe. A problem with a piston/ring/cylinder can allow the compression to leak past the rings/piston into the engine oil sump and pressurise it. Under pressure, the oil will try and leak to atmosphere from anywhere it can.
A blue smoky exhaust is also an indication of piston/ring problems. A quick check is to start the car. If there's a cloud of blue smoke at start up which clears quickly, it's like to be worn valve guides. If, when driving the car with a warm engine there's blue smoke on acceleration - it points to a problem with rings/piston.
A quick check is to remove the spark plugs. Is there engine oil on one or more of them? An oiled up plug indicates that the engine oil is finding its way up past the rings/piston - and if oil can find its way up to a spark plug, then exhaust gasses/compressed fuel/air can find its way into the engine oil sump and pressurise it.
Another quick check is to start the engine and remove the oil dipstick. If fumes are 'chugging' out of the tube or oil is spitting out, that's another sure-fire sign that the oil sump is becoming pressurised due to a piston ring/piston/cylinder problem.
If you possess or can borrow an engine compression tester there is a further test you can do yourself to confirm whether or not there are piston/ring problems. Basically, a compression tester is just a gauge that screws into the cylinder head in place of the spark plug.
Warm the engine for 5 minutes so that the pistons expand fully in the bores.
Remove the spark plugs
Fit the compression tester into No1 cylinder and crank the engine for 10 seconds. Make a note of the compression reading on the gauge.
Do the same for each cylinder.
Here's an example of what you might find (the figures are for example only)
Cylinder Reading
1 115
2 120
3 118
4 95
5 96
6 117
Figures vary, but there should not be more than a 10% difference between the readings.
In the example above you can see that cylinders 4 and 5 have readings that are well below those of the other cylinders. This is indicating problems within those two cylinders. The lower compression could be due to a head/gasket fault or piston ring/piston problem. A split or worn exhaust valve in the head may cause low compression, a misfire and uneven running but it won't cause the engine oil sump/crankcase to pressurise. Now, some fine tuning to locate the exact problem:
Put a liberal squirt of oil into each cylinder - something like Redex, WD40 or engine oil.Put a cloth over each spark plug hole and spin the engine to get rid of the excess oil. The idea is that the oil you have squirted into the piston bores will form a 'seal' around the outside of the piston/rings.
Do the compression tests again and note the readings. If the readings go up significantly it indicates that the rings/pistons/bore has a problem. Readings that go up significantly are due to the oil forming a seal around the piston which raises the compression whilst testing. Here's an example:Cylinder Reading on 1st test 2nd test
1 115 118
2 120 121
3 118 120
4 95 110 Significant rise - more than 10%
5 96 98
6 117 119
Ok .. all this means is that cylinder 4 has compression problems due to the rings/piston/bore. The 2nd compression reading (with the oil squirted in) is higher simply because the oil formed a seal. Cylinder number 5 still has a low reading which didn't increase significantly on the 2nd 'wet' (when oil is added) test. This suggests that the problem is an exhaust valve/head gasket/head problem.
If there had been no significant increase in the reading on number 4 cylinder, this would suggest valve/gasket head problem. Low readings on adjoining cylinders (and which don't increase with the 2nd compression 'wet' oil test) would indicate a faulty head gasket between those two cylinders.
I'll continue this article ... ran out of word space
SOURCE: Oil leaks from the oil filter adapter
If it is not the suggested gasket that is leaking then it is the oil pressure switch located exactly above the oil filter adapter. The black plastic housing could have developed a crack and oil will ooze downward and drip off the bottom of the adapter. I had this problem and changing the oil pressure switch took care of it.
SOURCE: Need to remove oil filter housing - oil leaking
This is not an easy repair in your driveway, but can be done. 1st thing, have you checked to see if the oil filter is the issue or is it the drain plug? If its the oil filter housing gasket, you will need to remove the filter. The housing is held in place by the threaded bolt assy that the filter screws onto. You will need to remove that bolt, remove the coolant hoses. Clean the engine block surfaces, for the new gasket to mate to, clean the cooling housing surfaces, install the bolt through the housing, and install the gasket onto it. Then install the bolt/housing into the block and tighten the bolt. Install the coolant hoses, oil filter. Fill the cooling system with the coolant that you removed. Fill the engine with oil, start and check for leaks.

there really isnt one it is not hard to figure out just take it off and look at it youll figure it out
SOURCE: My 2000 Ford Expedition has
Could be a number of things. Oil pan gasket, check around oil pan to see if its wet. Front crank seal could be leaking and blowing back if its bad enough. Check around and in behind your crankshaft pulley. I would also check your tranny cooler lines and power steering lines, if they are leaking bad enough the oil will get blown back when you drive. Also check to see how high up the engine the oil starts coming from that will give you some indication of where it starts.
