Need help pinpointing oil leak.

[AN292]

Finally got a picture today.

Check out the top left corner of the picture, that seems to be where it’s heaviest. Can’t imagine it’s coming from the drain plug. Any ideas? Not enough of a leak to see drips on the ground, but enough that I need to add a quart every few months.

Check your oil cooler block off plate (if you have that) or oil cooler plate. Those leak.. a lot.

Your oil pan seal could be leaking, too, at the back... which is very common.

You could also have the beginning of a rear main seal leak.

Have fun! Personally, I'd leave it.

If your not seeing it on the ground, it’s far more likely you’re burning that missing oil

I agree with ks03.

But, to track the source of your leak(s), you're either gonna have to wait until it gets worse and you're seeing wet trails or clean everything under there and keep an eye on it to look for the first hints of leaking oil. When driving, there are wind currents that blow oil everywhere so it's difficult to track the source. You gotta start with a clean slate.

UV die the oil -- that's how you find leaks.

I just addressed this on my rig. Had seepage at the RMS and seepage at the oil pan gasket/seal. Did it all including a new oil pump pickup tube and seal, torque converter seal and transaxle seal. I just had seepage with no drops but hate waiting. That oil cooler line block off plate or actual plate the lines attach at is a known spot for oil leaks.
