I have read that the early builds of the M271 suffer from a cylinder head problem that causes compression problems. This is due to exhaust valves sticking, guides/springs wearing, and carbon build up.
The fix is a new cylinder head.
I have read that the exhaust valve on the new head is smaller to avoid this problem. I cannot find any other reason for replacing the entire head.
I want to know if the cylinder head can be saved by doing a valve job.
I blew the head gasket on my car and suspect its due to this (My M271 is from the 2nd month build, one of the earliest). I won't know till a shop pulls the head, yet all the symptoms are the same.
