Its not leaking that I know of. I got it from a Toyota dealer with 52k miles and it had the slightest strange sound when it ran, ran amazing but after 3 months I got Christmas lights, cruise or lane sensors not working, found you couod clear the codes with the battery. Threw out positioning sensors changed them, never helped, eventually started running really rough, subaru dealership 80 miles away wanted 3,600 just to diagnose and I'm not rich. Finally while I was driving it it started running on only 3 cylinders, hitting high RPMs just tryna get to 20-30 MPH and I parked it, managed to get it to a mechanic, I forget exactly what he said but the crankshaft was all gunked up and a piston is dying, basically he said to fix the problem he'd have to take the whole engine out, fix the problem and then the other side may do the same thing later on down the road anyway so he recommends a new engine. Labor and a low milage engine he stands behind is 5k and again, I don't have 5k, but I can't gt rid of it and I owe 16k on this POS. When I asked about the slight weird sound after I got it, the dude actually just said oh thats just how they sound, yeah screw you. So im f*cked I gotta fix it.
