99 cobra broken timing chain

Which chain?
The primary (long) one or the secondary (short one)?
Normally, chains just don't break, but it has happened.
Make sure the intake camshaft didnt seize in the head,
which could have caused the secondary chain to break.
Low oil level could have caused that.
PM me if you need more info.

the long one but i havent pulled the timing cover off yet but looking down inside i can see the timing gear on the crank broke and is laying in the timing cover
There might be more to it than that.
You need to remove the timing cover and go from there.

also you will want to do a leak down test on that bank to see if any pistons hit the valves you may have gotten lucky though... let us know what you find once you get the cover off.
I agree not a common occurance, maybe something else happened first?
Damn, i've never heard of those chains breaking.
Keep us updated as to what caused it.
Sorry about the bad luck.

Like Birdman suggested maybe there was a Cam issue..
yup, its got me wondering and waiting for some word back.
Strange stuff lately, one guy on another board breaks an OE camshaft, and now this.
similar happenings
I had a gear on my crank break a while back. The chain was basically just hanging there loosely and the cams stopped. the pistons slapped the valves and bent them against the head (since they stopped when the cams did and some where still open). the drivers side of the engine lost compression and scratched the side walls of a few cylinders. I had some shiny oil after that, and needless to say, a huge hole in my pocket.
hope your situation goes well and there's no significant damage.

I have heard of driver's side cam gear bolts both breaking and falling out, I've also heard of tensioners failing. Both will mess lots of things up including broken chains.
Yep happened to me, getting ready to pull the motor this Sat and find out the damage
