I looked high and low to replace the seal on my valve cover that goes around the vvt valve. Someone on here said to use NAPA part # 10930, and it is a PERFECT fit. Thanks to all of you for answering my questions and I will be back. I bought a 2004 Mazda 6s with the 3.0 litre automatic that was wrecked for $600 and now have close to $2000 into it after rebuilding the whole front suspension. It seems to be running quickly but I am still dealing with some other issues. I plan to have a nice car when done
