oil injector help.
 

Hi there, I just recently got my rx7. It's an 85 with a 12a. Anyway the guy I got it from only had it for a couple months and didn't know much about it. I know the rats nest is gone but I don't know how to check if the oil injector has been blocked off. The guy didn't say anything about running premix, and I haven't been doing it. Just wanted to find out before I do damage to my motor. It doesn't smoke and it made a 450 mile trip with no probs, just want to be safe. Anyway, any help would be great, thanks.

from the passenger side of the engine bay, look towards the front of the engine below the water pump housing, the should be a little mechanism with a bunch of small plastic tubes coming off it going into the intake. if its not there,and you see a block off plate, its been removed

I have some oil injectors that I can sell you if you need them. If not... Be very sure to premix.

Here are some premix threads -> RX7Club search: Premix

Easiest way to know would be oil consumption.
As insane said though the mechanism with all the tubes coming out is pretty hard to miss.
