1964 Dart Grüne Hölle Road Course/Track Day/AutoX Project
12/28/24:
Here is a rundown of some of the work that has been accomplished:
I got the old (broken) camshaft removed. There were 2 cam bearings which were damaged as well.
Maybe it is possible that the bearing trash got in between the lifer and lobe - Could it be that caused the one lobe to fail? (The failed lobe was next to a trashed cam bearing.) the other 11 lobes were fine.
I had a partial set of cam bearings on hand so I knocked out the damaged #2 and #3 bearings and replaced them with the extra set that was lying around on the shelf. I do remember the bearings being tight from the build 2 years ago, but I did not know how to correct the condition so I let it go on the last rebuild... live and learn.
This time with the new #2 and #3 cam bearings everything spins well with or without assembly lube.
I got the new cam degreed in at 101.5° with a goal of Intake ℄ of 101°. The previous cam was installed at 0° offset to get the cam degreed in, this cam required 2° to get near 101°.
I cleaned up the tins and inside the engine a bit. Of course, there was some glitter, but nothing extreme like when a rod bearing fails.
The custom oil pan needs a bit of refreshing.
I had found a leak on the bottom of the pan 2 or 3 years back - I dabbed on some RTV sealer on the crack as a temporary fix, now it is time to fix it correctly.
If you followed the saga the entire time, you will recall that the valves in this head must be a bit taller, so when I switched back to the stock rocker arms in ~July 2023 they rubbed the valve cover on cylinder #6.
I fixed the cuts in the valve cover also with a dab or RTV, it worked well and kept the oil in.
Now it is time for a proper fix for this as well.
