Re: Oil leaking from oil filter area. Not from sendind...
The oil filters have a nasty habit of leaking. Certain brands are worse than others. All the oil cooler lines can leak as well. I would give it a good pressure washing at the car wash and have a look after. Couple days and see if you can find the source. Good luck and remember even a "bad" leak really only loses a half quart of oil over a 3 month period so it's not a major isseu for the engine.

Oil leaks can be a pain to locate so I will give you a few tricks I've picked up along the way for locating oil leaks. Start by cleaning/degreasing the area. You want to remove as much of the old residue as possible. Then you can do several things from here.
1. Purchase and oil dye additive (this additive makes the oil glow when a black light i shined on it) and run the engine for a little while then re-inspect with black light to find locations where dye is concentrated.
2. After cleaning, spray the are that you suspect the leak is coming from with a spray on type foot powder(powder sprays on white providing an excellent contrast to trace leak). Run the engine and follow the oil trail to source of leak
Oil filter adapter leaking ?, or bad gasket on oil filter, you can try tightening it, remove the oil filter and tighten the nut, i have never had any luck stopping the leak on either the adapter or filter with out changing the gasket/o ring, sorry with the information you supplied I can only guess.
Have a good day.
It is possible that it could be leaking oil from the oil filter adapter (Sometimes called housing) where it mounts to the engine block. Leaks here are pretty rare. More likely, your oil pressure sending unit is leaking oil. It screws into the back side of the oil filter adapter and can sometimes make it look like the adapter is leaking.
Sounds like the garage either installed a filter with a faulty gasket or the oil filter is not tightened, or there is trash under the oil filter gasket.
I'd remove the oil filter, clean gasket seat on block, clean oil filter gasket, check gasket for nicks/defects, reinstall oil filter if gasket is good, hand tighten (but tight as you can get it) and try again.
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 mins...no 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!
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.
I'm fairly certain that the parts stores carry the oil filter adapter gasket. Check around for it and make sure both surfaces are very clean. I like to use a FILM of sealant on both sides of the gasket and install. The reason why you use the sealant is to compensate for any irregulatities of both surfaces. You also might want to install a new oil pressure sending unit to the adapter while you have it off. That is another place where you could have a leak. They like to wear out prematurely also.
