Blown apex seal???

hi guys ill just start by telling you guys what happened. ok so i was racing around with my friend. and suddenly the car stalls, and takes forever to get started. when i finally got it started the shifter *** shakes like hell, same with the car. and the exhaust is just rattling like hell. basically my car sounds like a dying gerbil, i have to keep my foot on the gas or else the car will stall. there is absolutly no power, and my shifter *** shakes like its about to break.

(ps about 5 monthes ago i got a compression test rotor 1 = 5.0 and rotor 2 = 2.1, and he said that id have about 6 months to drive the car, does sound right?)

Could be, do a compression check now and see what it says.

Difficult to put a time frame on an engine when it's going to die, but from what you describe, I would say it's a gonner.
See below for a DIY compression test. Look in Tech section.

That's pretty much what mine did when an apex seal let go.

Before doing anything else, do the "cheap & easy compression test" as linked above. If you don't get chuffs from each face, it's a goner.

is it likely that both rotors didnt blow though, cause i think my car is running of one rotor, i can drive it. it just happens to go real slow and has no power and chokes and shakes.

You don't want to run on one rotor, you'll tear up the other half of the engine more so then it already is!!

Merf? The blown rotor is already scrap, the apex seals are toast, the housing is toast, and any interference has already been taken care of by the inertia of the engine.

You might want to disconnect the injectors to the blown rotor to prevent raw gas from washing through & contaminating the oil as much, but there's really no way to damage the engine more by running with a blown rotor.
