As the title states, im having an e28 fuel leak out/down the injectors. Ive gotten the o-ring replacement, and have done it on all six. What started with one is now two that leak fuel and run around the intake. Please suggestions. I assembled as disassembled, things are tight.

Yes they can, the fuel rails can crack develop leaks as well. Neither is really common though.

Oops, double post.

Ya, i had one seeping into the intake, and one leaking on the outside lol. I replaced them with some junkyard beauties from 733i for 20 a piece (The injectors for the m30b32's are the low impedance kind that only the e30 m3 and the e28 m5 share, so...177.99 each.) and voila, full torque ahead again. And i never noticed but before it didnt "idle down" once it hit its running temp. Now it purrs at 800.
