Help... No compression in front rotor WTF?
Allright the basic story is, my car ran fine for 100,000 miles then randomly started running very vey bad, then within 5 minets smoke from everywhere and I towed it. Ok So now I found there is absolutly NO compression on the front rotor. I mean the gauge does not even move on any of the pulses. The rear rotor seems fine but its hard to tell with my primative gauge. But with both top spark plugs removed the back is shooting air like crazy and the front is barly a puff. Anyway what can cause this to happen so suddenly, what went out? From what I fave read if an apex seal went out there would still be one out of 3 strong blips. Thanks for any help/advice

I lost all compression on my front rotor not to long ago but it didnt smoke from there maybe a seal between the housing and iron blew I havent heard of this before but maybe it is possable. I also just got a re engine were the front rotor would give me three good pops and the rear would give me two I thought if a apex went out then two chambers would loose compression. Dont know if I helped any but just my .02.

The motor is dead...for whatever reason.
I dunno what you're looking for, but arguing what went wrong is kinda moot?
Either get rid of the car or get the engine fixed...

What was the total mileage on the engine?
All you mention was that the car ran fine for 100k miles - does that mean you put on 100k miles total since you bought the car new or are we talking about added mileage?
Has the car been maintained correctly?
If it hasn't, if the motor popped over 100k miles, it's no surprising.
When a rotary engine blows, it gives very little warning.
How do you suspect the fuel injectors are clogged?
Try and get them professionally cleaned by a shop that does pre and post spray pattern analysis - this should confirm your suspicions.
I highly doubt this is the case though.

As has been previously stated, it's pretty easy to to lose all the seals on one rotor... Consider it dead, tear it out, and rebuild!
Alright, seriously, am I the only one who see's sponsored links all of a sudden?

Nope, I see them all too. It is pissing me off because my mouse hits one and I can't read the post. LOL.
Look at the "Race Car Tech" section on the main front page. There is even a "sponsored link" there too! hahahaha

There is a slight possibility that your injectors were so clogged it leaned up and detonated, but prob not. As ted said, send them to a place that does before and after flow tests to compare. www.cruzinperformance.com did a good job for me. Other than that, it was prob bad maintenance from the previous owner (the oil should be changed at least every 3k miles, with oil being added in between). Just for kicks, check and see if the oil is low. I just thank God I didnt have stock seals when my apex seal blew.

BTW: Is there some simple injector test just to give an idea if they may be screwed? Like something at home and slightly ghetto?
