leaks?
After having an oil change a few weeks ago i decided to have a quick look under the car to make sure everything looks fine (the car went back to the mechanic because they overfilled it ridiculously) and noticed a nice oil spot on the floor of my garage and oil on the engine floor cover thingy. Check the oil level and it has dropped a bit on the dip stick. Also found that the coolant level has dropped a bit too.
After speaking to my mechanic he said the apprentice may not have tightened up the sump and it has come loose or he possibly broke the washer or something along those lines.
after looking more i noticed this on the passenger side

the same substance is on the drivers side although there is only a small amount
anyway im no expert when it comes to motors but thats not from a loose sump. Could this be related to my coolant and oil loss or is it from the CV joint?
please help
