So after searching high and low I finally found a place here in town that would order me in the banjo bolts... if I made a minimum purchase of $50
, so I waited awhile and made a list of some stuff I needed and through these banjo's on the list. While I was at it I wasn't quite sure if this was worth doing or not and some guys said that the check valve keeps your heads pressurized on shutdown and that prevents a dry fire of your injectors etc.
So, I ordered a banjo bolt from Ford too to inspect the differences. I was quite amazed when I saw the ford piece...
So I am thinking to myself, how on earth does anything move through there? So I pull it apart to get a better inspection...
And to my surprise (well not really) there is a whole mess of stuff inside. And then I take a closer look at the check valve and see that there is a hole in the middle of the check ball that you can stick a .5mm piece of pencil lead through. So now I'm positive the head doesn't stay pressurized when you shut the truck off so I was a little less hesitant about doing the mod.
The new bolts have a lot more flow too them... They have 3 - 4.5mm holes vs. the 2 - 3mm holes in the OEM piece. Both have an 11mm shank. The upgraded ones have a 7mm free flow outlet as well.
Sorry for the long post but just got these installed on the weekend and thought I would share my experiences, no hard starting or anything like that and seems to run a little better at high RPM. Need more seat time and a free DYNO
Oh, and I have a few extra set's w/crush washers, put another set on our work truck and have a couple more if anyone is interested.
