V6 "cylinder Down"! What's Your Experience?

Just had the 2010 SE for about 2 months; 74K miles.
She was running just great......THEN....
I got an engine light, and found to be Misfire #1 cylinder.
We've done all the easy stuff, and looks like 90% compression loss.


What's the chance it's something simple like a valve or valve spring, rather than a cylinder head?

Pretty high chance it's valve train. Those things are notorious for eating rockers. Hopefully if you hung up a valve it didn't take out a piston.

So, I got my gal back today, and she drives like new!
Ended up with a new cylinder head, and cam.
Ring on the cam loose and chipped.
Had them pull the other side to check everything - all OK!
Chrysler "Good Willed" all the parts.
I just paid labor!

:D
