Since installing the new Cam (kept the bearings) and pump, I've noticed that I really don't get much oil to the rockers, not like I've seen on most others. If I rev to over 2k I seem to get decent flow, but even then, it seems like there should be more. I was very careful in swapping cams, and I know the bearings are good. I oiled down the feed hole for the rocker shaft prior to starting. Is there something else I should check? ~RDE~ |

Is the rocker shaft installed correctly so the oil feed holes line-up w/ the rocker arm oil holes? Did you check the cam's oil feed cross hole for correct oreantation? These can be mis-drilled in the cam and that reduces the amount of flow to the rocker-arms. The other possibility is that the rear cam bearing is not installed correctly or has rotated, blocking / partially blocking the feed oil holes. DD

He's using a cam I had used in the BV build. The holes are drilled correctly. With this cam I did use a Rollmaster timing chain and a Doc Dodge Cam Button (TM)....I wonder if the cam with his silent chain has moved the cam and oiling hole a sukoshi causing a slight restriction...  -D.Idiot |
