S13 SR20DET: Where to buy PCV T-pipe grommet? (valve cover vent, exhaust side)

[grilledgnome]

So I discovered my PCV vent pipe is missing a grommet, causing an oil leak that drips right onto the exhaust manifold for a lovely burning smell. Can someone help me find the right product number for the grommet, or a suitable non-OEM replacement? Or at least, provide a picture of your OEM part so I have a better idea of what I'm looking for? Perhaps the same part is used on other Nissan engines, so input from owners of such is useful too

From what I can tell, it seems that only the s13 SR uses a T-pipe for the PCV vent. But regardless of T, elbow, or straight, if the inserted end is the same size on other engines, the grommet should likely be compatible. I measured mine: 13mm inner, 15mm outer diameter.

For anyone not sure, this pic shows the T-pipe I'm talking about, located under the words "twin cam"
