Cylinder head question
I have a Dodge Dart 2013 1.4 liter turbo with some valve trouble. Initially (this car is a mechanic's special), cylinder #4 lost compression...so I pulled the head.
The head seems ok but the #4 exhaust valves are "popped" out of their seats...maybe 1/16"...just enough to lose all compression.
So I cleaned all the carbon off, lapped the two exhaust valves, reinstalled, and checked for leaks. They are still "popped out" and leaking like crazy.
Is this a manufacturing defect? Were the seats cut wrong? This car made 120k miles before it had trouble. I'm at a total loss for what's going on. The springs look fine. Thank you.
I'm attaching a photo of the valves before I cleaned them. You can see how the left one looks "popped out"
