Pulled the engine on my 240Z to freshen it and the engine bay up. Discovered two stripes on the camshaft when the valve cover was removed, one is red and one is white. Googled and searched the forum for something but have not found anything regarding stripes on camshafts. Anyone ever seen this or have any idea what it means? There are some stamps on the rear as well. The car is a 1972 240Z that is very close to original/stock. The engine may have been rebuilt at some point.

Hi, I wondered myself many times what is that wide red stripe (as big as the 2 of your stripes together) and it's still a mistery, i would LOVE TO FIND OUT!

I have never seen your combination of red and (what once was) white..

I asked it here on the forum and there was never a answer.

Nobody knows.. Maybe it has to do with the composition of the metal of the camshaft.

I think D1 (on the rear end) stands for a standard camshaft in 1972 datsun 240z's ?
