sorry about the double post, but I wasn't getting any response on the other one.
My fuel is somehow ending up in my oil. The only response I've had is about one injector stuck open. Is that the only thing that would cause this?

 

i think this is common to an extent on most rx7s

maybe an older motor would have more fuel in it

how bad is yours?

i like to change my oil at 1500 at the latest any way

 

i had the same problem so i took out the pcv valve and capped the hole on the uim, then ran a hose from the hole on the filler neck to a oil catch can and vented the the catch can out of the car.....works great,...

 

As was stated before, an injector which has stuck open will vent out and cause an over fueling but it would likely cause a drive-ability problem, the system would be a bit rich to real real rich. Another thing is the fuel pressure regulator. Its signaled by load/vacuum. If the diaphragm ruptures fuel will be drawn into the intake and could also cause this type of problem, surely other things can cause this as well. I would make sure its gas or an abnormal amount in the oil. Remove the vacuum line from the fuel pressure regulator and shake it, fuel may run out, also leave it disconnected and run the fuel pump and watch the connection at the regulator. If fuel drips out then its damaged. The carbon canister can also become saturated for other reasons not unlike the fuel pressure regulator and cause the intake to draw too much fuel in. John
