I have a 90 RX7 the oil lines that lead to the rotors from the little pump are broken. i am wondering will those cause the car not to start? also i am looking for a replacement for those lines. any idea on how much they are and where i can get them?
Aslo i heard that you acan clamp those lines and just use 2 stroke gas?? any one hear of that and or is doing it?

 

do a search for OMP block off or PREMIX, those lines can def be removed, should not cause starting problems, but I would NOT start that engine without those lines or a suitable premix in the gas tank you WILL blow the engine, there is a nice writeup some where in the Archives for OMP line replacement, if I remember correctly the guy fixed them for like 10 bucks or something, search for that too.

there ya go, some good info on OMP block off, don't think you can just clamp the hoses off

 

at a Mazda dealership will cost about $30 EACH.
or
look some up on E-bay.
