Just wondering what size holes most are using in their oil spray bars? I will be using straight 40 weight oil. I also assume they really drip more than spray (which is all they really need to do). The spray bars from Indy come with pretty large holes and seem like they would flood the top of the engine with oil. I would rather keep more oil where it belongs if possible. Anyone done any experimenting with this? The spray bars from Indy usually come with a restrictor in the fitting that goes into the valve cover. It's normally a drilled out grub screw. It is more of a drip, as you state and we've run them on the 528, 572 and 655 with no issues. HTH's Do you have any pictures of the "restrictor" that Indy uses? I have a set of their covers and there is no restrictor or provision for one present. Maybe my covers were converted to spray bar by someone else...
