My 1995 Cadillac SLS leaks oil when parked on a
downhill slope only. Three round areas can be seen
on the street at the front of the car nearest the area
of the radiator. Been this way for several years now
and doesn't use a lot of oil between changes. Is my
oil pan leaking or is it a rear main seal or ???
hummm what you need to do is get on some gruby clothes and take it to a do it yourself car wash or at home maybe and spray and clean all aroun the engine and UNDER IT ALSO re park it and wait to see on ground or frame or engine what has oil on it. up front you said..could be an easy fix..transmissin cooler line.power steering pump or hose.. front crank seal pan gasker..ANYTHING,SO DONT WIG OUT ...

Park facing uphill.
Check the oil pressure sending switch. They were notorious for leaking. If that's the trouble, replace it with an AC Delco switch only!! Aftermarket switches won't work correctly in this application!! HTH. -Jim
