OIL FILTER IS IN FRONT NEXT OIL PAN BUT HIGHER UP POSITION. OIL FILTER ABOVE THE BOTTOM OF THE OIL PAN WHERE YOU CANT SEE IT.IF HAVE TO RAISE FRONT CAR UP TO SEE IT.NEED SPECIAL FILTER WRENCH TO REMOVE IT.

well the ring should stay on the oil filter if there was one on there when you took off the old one it came off and dont need it

just about run in ,mobile tanks on wheels these motors ,but iam not sure where it is ,i change one a while back because it was leaking ,know it was on the side where the oil filter and it was level with the oil filter because the oil gallery is level with the oil filter

if you think the filter gasket is leaking take filter off check for double gasket if it is replace the oil filter and take off 2nd gasket.

driver side on front of the radiator

The engine oil filter is located just right of center if standing in front of the car. By removing the LARGE Black cap with the 36mm nut you will expose the filter element, make sure to do this before draining the oil from the drain plug in the pan. Otherwise the filter will still hold oil until loosened a bit. A typical oil change should go like this.
1. Engine Hot, not running, Loosen filter housing, don't remove yet.
2. Drain Oil, Replace plug.
3. Remove and Replace filter and O-Rings
4. Add oil.

The oil filter sometimes starts leaking from old age, and if its been a while since your last oil change, just have your oil changed. On the other hand, your filter could be loose. Grab a rag in your hand and try and tighten the filter by turning it to the right. If it's loose, tighten it hand tight.

I assume that you have a 1.8 engine. The oil filter is in a round metal housing under the engine; you have to remove the housing to access the cartridge type oil filter; the 1.8s do not have a "spin-on" filter.
