Hey guys vocky corsaZ22se got a bad oil leak coming form drivers side of engine its leaking oil onto the right wheel going all the way to the back of the car. Any ideas where it could be coming from. Looks like its predominantly travelling under the car. Im thinking oil seal in the oil pump cover??? Coolant is clean. Found this out when i took the car to a garage to have the brake fluid changed. They refused to change it unless i cleaned it up underneath first, So what do i need to look for once ive degreased the engine to find out where its coming from.
