did oil change on 2004 Honda odyssey about 2 weeks ago .this morning I notice a puddle of oil on ground plug is tight and filter is tight?

Hi because you should have also changed the drain plug washer as well so now it leaks.

Make sure the oil filter gasket is still in its seat on the oil filter. Also, be sure you have the correct oil filter for your engine. Being tight doesn't mean the gasket is seated properly.

A remote possibility is your oil pressure sending unit has sprung a leak.

Maybe the shop didn't remove the seal / gasket with the previous filter?

Filter gasket could have slipped out. Unscrew the filter and see. Puddle, huh? Check the dipstick to see if oil is missing. Some acs-hoal might have poured oil down there to eff with you.

That's nice. Did you want to ask a question?

Its gotta be coming from somewhere, look for it .

did the level of oil in the engine decrease ?? if so then ther's a leak somewhere that needs to be fixed
