Oil pan leaking from black square plastic part, what is this part and is there a common problem with it like o-rings or seals?

there are two black plastic parts I can think of. On the bottom of the pan is the oil level sensor and on the back is the oil cooler.

If its this one then the oil may be leaking from the orings or the cooler may be failing. best to check where it is leaking from and if you can not determine replace both the o rings and the cooler.

You will loose some coolant and oil in this procedure so have some ready to top off

Ok - I don't see a oil level sensor in the pan so perhaps it does not have one

I have this problem going on too, one very similar to it. I took it in to my mechanic, just seeing that I had oil leaking under the car was enough for me to have him take a look at it.

After the analysis my mechanic told me it was my rear main oil seal and to get to it would require dropping the transmission, which is a big job. He was willing to charge me about $600 for the job, but in the meantime I have been keeping up on the oil levels and checking it very frequently.

I don't know if this will help, but hopefully maybe get something out of it. Good luck.

I'll double check but it's leaking at that part, not above it. I brushed the underside with simple green and lightly powerwashed where ever it looked oily, then let the engine run for a while and it is coming from that part, which again is a little loose so when I get a chance I'll tighten it down and hopefully that will fix the problem. I just didn't know what that part was!!!
You know, if Volvo just kept it simple without all these extra dodads and whatnots, maybe it would be a much more reliable car!!!
