Ok, now correct me if I'm wrong...but the rotors spin at separate angles, so that when one rotor is on the combustion chamber as the other is on the intake, or something close to that, right? Well, while I was trying to do the ATF trick ONE more time on the rear rotor, I came across an interesting thing...I couldn't get the hose in the upper Trailing spark plug holes on both the rotors...meaning that they were in alignment(or very close) to each other...is this normal? I also heard a grinding/scratching noise... coming from the motor when I spun it over real quick...which I'm sure can't be good...

...Is it possible for one rotor to be frozen, and the other still run?

heh....The trailing spark plug holes don't fully open up to the insides of the housings. The hole is only like 2mm in diameter, so I doubt the hose you were using would fit through. I'm sure you already knew that though.



The grinding doesn't sound good though.

The rotors should be 180 degrees apart.

you have to use the bottom hole the top hole is tiny. if you hear scratching that is probably a broken apex seal scraping the housing ...... i would pull off the exhaust manifold and spin the engine. use a mirror you will be able ot tell for sure whether or not the engine has a broken apex seal........



13BAce is right the rotors are 180 degress apart, you'll notice the eccentric shaft has two lobes on opposite sides

Yea, I knew about the small hole, but I figured the small scribe/probe thingy would have fit...anyways...thanks for the info, I thought they were opposite, lol...just had to reassure myself, ya know.....I really hope it isn't a broken seal...I don't feel like replacing the damn housing or rotor!

You know after reading this post ( I think it was this one), I had no idea that the trailing and leading spark plugs were different! I went out and took a look at the ones I bought from Schucks a couple weeks ago and all four had a T on them. I took a look at the ones I had replaced and sure enough two were T and two were L. ******* A, now I feel like a moron, but hey thats what the guy gave me so its partially his fault (but mostly mine).

i run four *9*'s

yea it will run on 1 rotor,but a short distance&not long. efi will keep fuel coming and exhaust will get super hot.sick feeling afterwords.

i got my first rx7 to run on one rotor it had 230k miles original everything bought it for $200.... anyway. i drove around my block at 5 MPH i felt badass

lol he said schucks

lol we have a store up here called Schnucks it is a grocery store.
