I have a 2011 maxima with over 200k miles, I just need it to last a little longer. The car runs smooth, accelerates well and overall no problems, except for a sludge build up under the front passenger side and I cant find a leak. I change the oil with synthetic about every 3-3.5k miles. I've checked the boot for the cv joint and its not torn or leaking. There's a small hose very close to the oil filter housing for coolant, and I have checked and changed that hose also. Other than the sludge build up, the car runs fine. I just want to find out what it could be so that I can squeeze a little more life out of this car. any help would be greatly appreciated.
Are you sure its not trani fluid? Smell it should tell you.
It's definitely not trans fluid
If it’s right by the coolant hose I would look at either the oil cooler o ring those can leak and build up right there and also the oil pressure switch lives directly above that hose and can seep over time and build up in that area. Hopefully that helps
Thanks, I'll look into that
Just found a video on youtube, I'll fix it soon. Thanks to both of you for responding 👍🏿
