I changed the o ring behind the oil cooler but there is still a leak from that area. About a quarter size spot per day. Could be coming from oil pan? Cant see exactly where it is coming from. Any ideas?

I have a 2004 nissan murano and I also have an oil cooler leak. I went to the dealer and they told me I had to replace the engine oil cooler o ring and price was about 175. I wanted to know if i can do the job myself, and save the remainding money perhaps on a full tank of gas, which in CHICAGO, is about dollars.
Put something under the filter to catch any oil drain, remove the filter, remove the center tube the filter screws on to, replace the gasket, put everything back together. You will need a large combo wrench for the tube. I think I used a standard size since I didn't have a metric wrench that large. I think it was around an inch or more. The tube doesn't need to be super tight, just a good amount tighter than what a filter would be.
