FYI there are 4 different valve cover gaskets, I called the Felpro
tech line and they told me how to match them up.. There are 5
 valve covers I think he told me used on the 2.5 over its production history.

NAPA had the one I needed, nobody else did, I have the Cast Aluminum cover without tabs.

If it was rebuilt and then leaked, most likely whoever installed it probably torqued the head wrong.

The torque spec on these heads is pretty high and most people use the wrong socket on the head bolts. So slap on a new gasket and off you go. At least it was good luck on the head already being rebuilt. The machine work on the head is the most expensive part of that job.
