EDIT: Problem was a leaking oilpan gasket after oil change, seems it wasnt seated properly, young new technician.
But only the 2nd oil-change ever, finding this strange, I've never replaced oil drainplug gaskets during oil change, I guess I need to buy one of those $40 valved oil drain plugs permanently mounted.
is replacing gaskets every oil change a thing now? I've also always only had steel oilpans, I guess oilpans are all now aluminum, horrible place to save weight!!
One more reason everyone needs a skidplate!! these stupid aluminum oilpans, hit a pothole one time you arent just blowing a tire, any contact youre cracking an oilpan destroying your engine if you dont shut down immediately.
------
Leaking oil this morning from bottom of the skidplate. Couple days ago had oil,ptu, rdu fluids changed.
Looks & smells like the motor oil, but the dipstick shows full covering the top dimple cold.
--Ruled out PTU fluid leak since I have a bottle of 75W85, definitely thinner & doesnt have the PTU "onion" smell. Brake fluid thicker, clear & full.
So last oil source is hybrid drive, but I don't know what hybrid drive Mercon ULV looks & smells like & how to check it for leaks, could this oil be Mercon ULV?
I also 1 week ago had the car spray undercoated with Krown rust proof oil, doesn't look like the thicker Krown. Now I wish I hadn't, gonna suck looking for leaks.
1) Came out today to what looks like motor oil spilling out, yesterday had a 180mile drive.
oil, rdu, ptu fluids changed 4 days ago & haven't notice any leaks before.
Checked dipstick and oil is filled all the way. Color/smell on the floor matches oil on dipstick.
2) oil leakage is all at the oilpan change port, I haven't been under yet with skidplate off.
PTU is near same location as oilpan, but I have a bottle of Motocraft 75W85 & it is definitely not PTU fluid which is thicker with a distinct "onion" smell.
3) felt around the oil filter, oil filter is not oily even though in pic you can see some drips below it, may have migrated forward on the skidplate.
4) process of elimination: not brake fluid.
5) I will get dirty pulling off the skidplate & check for loose oilpan plug,
Question: if engine had been overfilled, would it spill out at some vent location so I dont need to worry?
Maybe the technician accidentally spilled oil on the skidplate when changed a couple days ago, and spilled oil only ran forward to spill when backing up my driveway.
That seems the most logical but I don't know what hybrid transmission Mercon ULV looks like, kinda scared if its a hybrid tranny leak that I wont be able to see it.
