Have a 2000 stratus 2.4l dohc. Compression test shows good on cylinder #1, but ZERO on 2,3, and 4. Does this sound like a busted head gasket?

Accidently shifted into revers at 70 mph. Didn't hear a loud bang or anything of that nature, it reved to about 7,000 and drop out. Honestly I can't think of anything besides a head gasket that would cause this.

Thoughts?

 

did you try squirting a small amount of 30 weight oil into cylinder see if compression goes up, if number climbs bad piston rings , have you checked timing belt could have jumped a few teeth or broke, could be bad head gasket, bad or worn valves, cracked head

 

did not try the wet compression test because compression read zero instead of low.

Will be pulling timing cover and head today, hopefully I'll be able to see what's going on in there

 

Hit a snag at the harmonic balancer. I removed the pass side motor mount and dropped it as much as I could, but the balancer doesn't clear the frame. I'm thinking of removing the driver side mount also and sliding the motor towards the driver side to get the clearance I need.
Anybody have experience with this?

 

I've never done a 2.4 but have read you might be able to get it off by removing the splash shield, have also read you have to lower the engine/transmission to remove

 

sounds to me like it done blowed up !!!

 

Timing belt snapped. Valves in #1 were close, that explains the compression. Hopefully the valves didnt catch each other, ill do another compression test today

 

Yes you have to remove the splash shield in the wheel well in order to remove the balancer. Make sure you use a good heavy duty THREE jaw puller on the balancer so that you dont chip it on its way out. Place the puller properly on the balancer. It has indentations where you can attach the puller towards its center. You may have to use a socket extension on the puller towards the end of the pull in order to get the length to remove it. Good Luck and be patient...
