So mine took a dump! and the cam got a little wear on it!

it was a nice C datsun comp cam!

IS there any upgrade for the oiler tube?

or do I just have to replace or get a a self lubing cam?

No competition version of an oiler tube. Cam towers are different for an external lubed cam vs. an internally lubed cam.

MSA sells em for $65.00.

Really? My internally lubed cam shaft came with plates to bolt over the oiler tube openings. It seems to work, because the engine has run for years that way.

hmmmmm

The oiler tube openings are plugged on the internally oiled cam towers or in your case the cam manufacturer supplied block off plates and gaskets.

When my internally oiled cam was installed in 1980 by the dealership they put little oval plates over the holes, as per Walter, no gaskets. 5300 miles later, everything is fine. There will be a hole at the back of an internally oiled cam that will need to be pluged before use. Using an internally oiled cam WITH a cam oiler is nice insurance.
