I never notice any stains on my driveway but today as I was doing an oil change, I noticed something is leaking,but from where?
There doesn't seem to be any fresh oil anywhere and i never notice anything on my driveway. What do you guys suggest? Btw, I changed the rear main seal 2 years ago.

 

Looks better than mine.. I wouldn't worry about it

 

If you dont know from where did come out then probably is puked ATF from the trans Breather tube...

 

remove the inspection cover under trans/engine connection--2 small bolts
if engine oil in there its rear main seal
BUT
we have found clogged PCV $10, forcing pressure and oil past the rear main seal!!
replacement solved leak

if its a really odd fluid ck the motor mounts, front and rear

 

what would cause that?

 

That could be old oil from the rear main or you may have a new rear main leak. It also could be from a valve cover. Clean it up and drive it a month and see if it shows back up.

 

It is a sign of leaking if you didn't see it before. Do as said above to inspect where the leak comes from.

 

remove that cover, wipe it dry inside if needed,,drive and monitor
ck PCV valve,,may as well replace it based on age, under 10 bucks- any parts store

back in the day we changed these every year!
