Well as it turns out the the pcv hose for my 77 280z w/L28 has been discontinued thru the dealer. Also upon further searching the parts houses where i live do not even show a listing for it. ( CarQuest, Napa, Oreily's, AutoZone) So I decided to ask if I could look at there molded heater hoses. To look for a close match. I found that the Gates Heater hose PN 19726 fits with some cutting. It is not perfect, But it does not kink when making the transition from the block to the pcv at the bottom of the intake. Granted you can find the original hoses (NOS) online but they are $50 +/- So Why not just spend 15 bucks and have an alternative route :thumbup: This hose features the belled end to fit over the block end metal extension and necks down to just over the size of the pcv inlet.
Here is the broken original PCV hose, im sure if you are looking at this post then you are familiar with how brittle they are and break easy
Here is the part number tag
And here is the section that was removed in order to fit..
Installed photos of the actual piece retained after excess was removed. If you look, you can see the belled end at the block and the slightly over sized end at the PCV. The over sized end needn't worry you After I installed this, I smoked the system and no vacuum leak was detected.
I really hope this helps you guys, I know that I was getting upset searching for these with no luck and only finding ppl selling randomly for more than 50 dollars for something rubber and so simple.
