Good afternoon/evening everyone.
I purchased used 2010 Chrysler 300c, AWD V6 3.5 with 170k miles on it. I got misfire on cylinder 5, my mechanic replaced the plug and ignition coil but I still get the same code.
After compression test, it was revealed that cylinder 5 Compression is at 90 (low) should be at 160 psi.
After removing the value cover gasket, he told me that the rocker arm seized !!!!!
Is this something fixable because he told me that a big job and he has to remove the head or I need to put new engine?
Anyone else with the same problem?
Any tip will be much appreciated.
Thanks
