So just a minor update. I degreased the bottom of the engine mainly around the affected areas. It does look like the rear seal on the transfer case has failed. I am watching it daily for any signs of leakage, but it has only been a couple of days and there are no visible signs just yet. Thanks for the help.

Thanks for the information. I had watched a couple of YouTube videos (Highlander) engines and see that it is a reasonably straight forward process. However I will talk with my local Toyota dealership and see what they say. Definitely worth having done! I will update the site with my findings. Cheers.

Hi, thanks for the replies. I will give the engine a pressure wash tomorrow and take it for a spin. Hopefully it will show what's going on. The pipe felt okay. Is there a procedure with Toyota for getting it replaced? Is is replaced for free? Cheers

Hi, I have conducted a search on this site in regards to engine oil leaks and most of the search results indicate the oil cooler rubber lines failing. I own a 2010 KXS AWD and noticed some oil leaking - looks like for a long time now extending back on the underside of the car from the rear of the engine. I read up about the oil cooler hose failure and took the front splash cover off and had a look there. It looks okay (at the moment) I still do have the rubber hose set up in place. But not a huge amount of oil around the mountings. I've added some pics below. I looked under the bonnet and looks all dry from up top and couldn't see any oil leaking from up there - yeah I know gravity ehh! I then looked under the car behind the front wheels on the drivers side and saw wet oil around a banjo coupling. The banjo join is towards the top of the pic (sorry for the darkness in the pic). Is this a known failure of the system? Looks like it has been occurring for a while as there is a bit of dirt encrusted oil extending a small distance back, so I guess it might only be a small/slow leak. Looking for advice on a possible solution or is there any other possible point where the oil could be leaking from?
