If you are talking about the oil pump cover that the oil filter screws on to, I'm not sure, but I think you should still be able to get them from the dealer...It is called the oil pump cover...
If the dealer doesn't have them, then TA Performance has them...
If yours is scored or grooved from the oil pump gears, try using an oil pump booster plate(It's a flat steel plate that gives the pump gears a new flat surface to use as a thrust plate...If that doesn't work, then you can take a piece of flat plate glass and some sand paper and sand the sealing surface of the oil pump cover flat again(not the timing chain cover!!!)
Hope this helps...
