Oil leak

My 2003 w209 270cdi has developed a large oil leak. It appears to be
coming from the back of the oil filter housing, running down the block, only leaks when running, but it comes out quite fast. Any suggestions

I would check the oil filter first before doing anything. If tight and it has the rubber gasket then I would put die in it to see exactly where it is leaking

NO LONGER ACTIVE
If it's not the seal on the oil filter cartridge, then it's the oil cooler. Either it has ruptures, or needs a new gasket.
