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:

  • 5.75 litres + 0.4 litre if the oil cooler is drained
  • Turbo - 3.85 litres + 0.6 litre if the oil cooler is drained
  • These figures are for a UK 3 litre version of the 960
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: 2001triton v10 oil leak

i believe you are looking at the oil cooler, replacing the gasket is not that difficult, drain the radiator, remove the oil filter and it should be 4 bolts and the whole assembly comes off, keep in mind though its more common for the oil filter itself to be leaking rather than the oil cooler gasket.

SOURCE: Oil leaking from front differential hose line

There are to plugs on the passenger side of the center carrier. The top one is the fill plug. Remove this plug and fill to this hole. If you are familiar with filling a rear dif then it is the same method. Please rate or tell me if you need more help.

I have a 2002 dodge caravan the oil is dripping on the ground when the engine is working


check where the oil is coming from first. check around the oil filter for leaks. if from the front of the motor check power steering and hoses for leaks . Around the radiator check for hoses to the transmission cooler . Check for leaks around loose sump plug. check for oil leaks from rocker cover gaskets running down the block at the back

I have a leak that appears in front of van i can't tell what is leaking


Assuming you see liquid somewhere, it can only be one or more of these fluids:
Fuel (gasoline)
Oil
Coolant (water/anti-freeze)

Normally, these three are separate, and all can leak. Depending on the quantity of the leak, only fuel is truly dangerous because it can catch fire easily. Minor oil leaks can be ignored for years, as long as you check oil and add as needed. Minor coolant leaks can also be ignored, as long as you keep the level up.

Coolant leaks are typically caused by hoses getting old, and replacing radiator hoses isn't difficult, just messy. Oil leaks are often harder, though the last one I fixed turned out to be trivial (oil filter loose).

I have a BMW 545i 2005 it has an oil leak and I can not find it the oil came out very fast so I'm thinking it has to be a bad oil leak any idea where this could be coming from or where should I check.


for oil to be pumped out so quickly I would be checking around the oil filter (Loose -cracked at seam) If there are lines to an oil cooler then check them for leaks or failure.

Oil leak hose coming off oil pump image


I think that you are refering to the power steering pump an the oil hose is leaking from a fitting or a hole in the pipe. Check the tension of the fittings and tighten if loose . Take the vehicle to a steering specialist to determine the exact position of the leak.

There is a oil puddle unnder my 1992 nissan pickup every time i move but the oil level is fine????? and i know it's leaking because i got under it and ran my finger along the oil pan and it was wet with...


you could have leaking valve cover gaskets leaking or a bad oil sending unit (oil pressure gague) .. make sure the oil is not red .. that wiould be a transmission leak .. over thghtning of the oil filter can cause leaks .. a clogged PCV valve can force oil out thru seals .. one way to track down leaks .. is to spray the engine with an engine solvent like Gunk .. then wash that off with a hose after it sits for a few minutes (keep water out of distributer).. that will clean the surfaces pretty good .. then it becomes obvious where leaks are coming from ..
if the oil turns out to be red in color . then look for hoses from the transmission to the radiator (transmission cooler) .. those frequently leak ..

Coolant leaking into the engine oil. I'm guessing


its more than likely either your head gasket or intake gasket. You either have the 3.4 or 3.8 engine and they are well known for these to leak.

Oil Leak


The oil leak at bottom of radiator could be oil cooler and/or supply hose. Try check closely for wettest area .
The other leak could be thermostat cover, it only uses a sealing ring and is prone to leaking after time.
