Bushing leaking a lot of oil once it gets hot?

Can you get them remeasured?

What direction are they wearing from? To or away from the pressure feed?

These bushings still measured good before it was put together this last time. They only have about 16 passes counting 12 dyno pulls on them. I am thinking about taking it to Phillip or Rich and let them look it over to see if they can straighten it out. I have already invested a small fortune in this thing, and I hate to keep throwing good money after bad. I am just low on funds at this time because I have invested so much into it. My plan is to probably take a year or two off and save up some more play money (I definately overspent my budget this year), and then take this to one of them and have them fix it.

I had kinda the same problem back in 06 with my SVO block.
The pushrods just werent getting enough oil and would
actually get this bad:



After talking to a number of engine builders I heard stories of
some Mopar hemi engines having the same problem until they
grooved the roller lifter hole. The Crane roller lifters at that time
actually came grooved for BBFs. Kaase also provided them.
At the time I had Cam Motion roller lifters and Kaase told me
how to do it myself with a cutoff wheel.

Once I did this my pushrod problems were gone forever!!! And I've
used grooved roller lifters ever since. IT WORKED FOR ME!

After I got back from TN I was doing my regular maintenance and found the pushrod side of number 5 exhaust rocker black, upon inspection the pushrod was starting to gall up. This engine has had the green oil in it ever since broken in w vr1. I was out prior to the TN race and had to fix the oilpan from the previous outings bumper dragger so I had to put vr1 back in. After swapping the parts and oil I noticed all the the ex rockers were not oiling while it was running. Turning up the oil press did no good. I have the same lifters pictured above........ I ended up pulling the lifters out and slotting the holes like I have in the past. Alls good now.........I'll tell ya this all jokes aside about the green oil I feel it was a crutch to my oiling issues and won't run without it ever again..........

That is the weird thin about i, I have grooved my lifter toget oil at all times during the valve sequence, and not just a little. It is a significant amount, and still galling them up quickly. I spoke with a gentleman about pushrods & jesel rockers, and he is telling me I teed h-13 tool steel tip pushrods when running the jesel rockers. Any thoughts on this? I currently run a Trend, 4130 pushrod. He said the jesel cups are h-13 tool steel so the pushrods should be as hard or harder.
