I have a small leak and supposedly its coming from the oil filter adapter and the part is called the oil filter adapter gasket, which I think are o-rings.
Please correct me if I'm wrong. I can't seem to find this part anywhere. The Cadillac dealer says its discontinued and I need to go aftermarket but like I said I can't find it.

Any help in this matter would be greatly appreciated.

Not o-rings, more like rubber barrels or pieces of tubing. They may not be available separately, but are included in the top gasket set. The barrels are compressed during installation to provide a good seal against the pressure.

how do I search for that, I did a top gasket set for the 4.9 and to many things should up don't know how to narrow it down. Would you have a brand and item number for this?

Felpro gaskets are always the first choice......

Here are some pictures of where the oil leak is emanating from, however I can't pin point which of the 4 bolts is the culprit.
