Look this is how you diagniose engine oil leasks, First have the engine pressure washeed top and bottom, get it clean, then go to a parts store and install a bottle of die that glows under a balck light, drive the car a week and have a shop put it up on a rack and inspect the engine for arear's that glow, then you have a good chance of fixing the leak the first time around.

SOURCE: oil leak from engine filter

The problem here is the switch inside the oil filter housing, or one of the lines attached to the bottom inboard side of the housing is clogged (oil return line). I just had this repaired. The oil could not return to the motor freely, so pressure was building up in the filter canister and leaking from the cover. The switch is called the oil pressure regulator switch, I believe. The filter depresses a little button at the bottom of the filter chamber. My oil filter was damaged apparently by the use of non-synthetic oil by the previous owner. Please have this addressed as this can lead to engine damage due to oil starvation.

SOURCE: rather severe oil leak from the area of the oil filter

I own a '99 Isuzu Oasis, which of course is really and '98 Odyssey with Isuzu nameplate. 214,000 miles, Cranked it up yesterday morning after 20 to 30 degree temps that night....took middle schooler to class approx 3-4 miles from home and approx 1/4 mile from home- noted severe burning oil smell in cabin and smoke from under hood.. Got it home and observed 3-4 quarts of leaked oil on the ground where I had been sitting just 15 mins before. Thought for sure I had ruined the engine after seeing all the oil in the gravel. Could not believe the leak was so severe, considering this car still runs like a beauty and has shown no leaking or other symptoms in the days before this occurred. Got home later that day and checked filter thinking maybe it had loosened. It had not. Refilled engine with oil and noted oil not leaking or dripping but pouring through area at engine block and oil cooler juncture at filter area. Found this forum and a few others on line and followed the plan , AutoZone: loan-a-tool 30mm 1/2" drive socket is all you need to do the job, except of course the oil cooler seal/O-ring which I got at Honda for 3 bucks. Took me all of 45 need to dettach hoses and leak antifreeze, just unscrew the 30mm nut and remove the old gasket/seal. Be sure to remove all the pieces, Mine was hard and brittle and broken in 3 pieces. What once was rubbery/pliable would now snap like a pretzel due to age/wear. When I buy my next one of these, and I will, because it is the best vehicle I have ever owned ( and I have owned several Hondas and Toyotas) I will preventative replace this seal at approx 150,000 miles.... this was close to being catastrophic failure- Thanks to this forum and others for the advice-plan to put another 100,000 miles on this baby!

SOURCE: Oil leak around #1 spark plug of 2002 Ford Escape

Sounds like valve cover gasket is leaking. It leaks down side of engine onto everything in it's path. Stop by a local parts store and have them take a peak, they'll be glad to help you out.

there is also a small valve body you are supposed to replace when replaceing the phasers... also there is a ssm for replacing the valve lash adjusters. alot of time the small engine tick you hear can be a cracked exhaust manifold too so checking those really close is heavily advised because the cracks are really hard to see sometimes. i have seen broken push rods on these engines and they can be a pain to pinpoint where the noise is comming from. hope this helps

Would recommend to steam clean complete engine compartment, to include the bottom.

Next, top your fluids and place clean towels or rags. Start your car until leak is present. With flash light Che k where from. If fluid is redesh in color, it's transmission fluid. If it's dark brown or black, engine oil.

Check bottom of oil and transmission pans for possible cracks or damage.

Massive oil leak suddenly on 2000 vw beetle looks as though came above oil filter and awhinning pumpsound present

That's the oil filter cooler seal. My car did the same thing; poured a quart of oil out on the ground in about a minute while I was looking for the source of the leak.

There's a box with radiator fluid going through it mounted between the oil filter and the block to cool the oil. It's got a large o-ring to seal it, and when that seal goes, it just *pours* oil out. Take the oil filter off and you'll see a large nut. take off the nut and the cooler will slide off - you can do that without removing the fluid lines.

The seal is between the block and the cooler and will be very obvious when it's bad; mine was missing a big chunk out of one side. Popped a new seal in, put it back together and haven't had a problem with it since.

Bottomed my 98 jeep cherokee in ruts discovered a oil leak broke is it possible it that it broke the seal loose on the oil pan when it hit. its in that area around the oil filter and cooler lines

If you dented the pan, it's possible but still not real likely that the rail gasket was damaged but I'd actually look at it real closely and first, see if it's trans fluid or engine oil that's leaking, then clean everything off, start it, and find the exact leak source. I've broken the trans cooler lines at least three times going off-road, in the same place you say yours is leaking....The last time it happened, I re-routed them to keep it from happening again.

I have a 1987 Vette that has never dripped anything onto the driveway, until last night. It is really leaking good all of a sudden. Where should I look first.

First you need to identify what's leaking? What color is fluid? Green, Red, Brown? and where under car is fluid leaking from center, front rt, etc... Another option is check ALL fluid levels - coolant, oil, power steering, transmission.

Possible oil leak

Sounds like you may have a valve cover leaking and the oil is dripping down on the manifold., burning off when going down the road. When you drive the air will blow this oil everywhere making it look like it 's coming from different places. The oil has built up around the frame or bottom of engine and that's why you're getting leaks on the ground. You can replace this yourself, no special tools. But be sure to keep a check on the oil level.

My suburban will crank the engine dut will not start

If the oil pressure sensor is defective and or fails to have oil pressure, it is a failsafe for engine protection. Try this: If the oil pressure gage or light show that oil pressure is present, but it will not crank, then open the fuel line at the throttle body a slight amount, ie. two flats then turn the key and starter just a wee tap or two and have some one watch the fitting for fuel pressure flow. If it leaks as it should, then you have your fuel pump working, however, if still no fuel then you must ck the inline filter under the frame. It could be completely clogged, there again, you could loosen the tank side of the filter and hit the key again and watch for leaks only if you don't get it at the throttle body. If you don't get any pressure leaks (you will get gravity leak on the tankside of the fuel filter) ie, squirting out, then you will likely have to replace the intank fuel pump. '
good luck
