I didn't replace the banjo gaskets and I took the 3 injectors out on the rail directly under neath the intake manifold and 2 of them were cracked so I replaced them. The third one was fine and the o-ring seemed to be in good shape. I am guessing the banjo gaskets or that 1 o-ring gasket that looked good is leaking every so slightly. The funny thing about this is that I am getting 20 mpg so it isn't effect my mpg at all! <img src="/forums/images/graemlins/lol.gif" alt="" />
