Are the mains the first bearings in the order, or does it go to the cam bearings then down to the mains?

 

Cam bearing oil passages intersect mains oil feed passages. So oil going to main bearings is tapped into to feed cam bearings, making it reach cam first mains second. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
