Hey I just need some confermation about something I am 90%sure about. I was driveing my 89 T2 around and I did not realise that my O2 sensor was disconected. Ah and then my car started running shitty. Like i said before, no power, didn't iddle blah blah blah. So what I am pretty sure what happend is that it caused back pressure and blew my apex seals apart. What do you think?

 

Are you asking that because the O2 sensor was unplugged your apex seals got blown apart? That's very doubtful that the O2 sensor would cause that, like pretty much impossible as far as I can think. The O2 sensor should only affect gas mileage, and very minorly at that.

You'd know if your seals were blown pretty well.

 

im not 100% sure....... but my o2 sensor has been disconnected on mine since i did my turbo swap, and i havnt noticed anything except the car runs really rich... (but then again, i havnt seen it run w/ the o2 installed)... but it idles fine, has plenty of power, ect.....

 

back pressure would not blow out apex seals.

Improper timing, or detonation, or lack of lubrication, or just plain worn out takes out apex seals.

and an O2 sensor would have little to do with your problem of low power.

 

damn.....quicker typer

 

Well thats what you get for not knowing anything about rotary. I am learning slowly. Thats why guys like you are awsome. Ok, well the car has only 60K on it, but mabey the guy who had it before me abused the crap out of this car. Damn, well its at the mechains now doing some tests. Thanks guys relaly apreciate you guys putting up with the noobs

 

having the O2 disconnected would cause the engine to run richer than normal, this usually is better for the engine than running lean. my O2 sensor has been dangling ever since i bought my car cause i haven't had the time to rewire it, i have put over 5k miles on it without an O2 sensor.

 

The ECU only reads the O2 during idle and cruise...

 

Ya, it doesn't make scence your right, me and my mechanic now think its probably a big *** vacume leak
