Also does anyone know if the new ford head bolts any better then the original ones or should I go with the APR ones? The APR ones are very expensive!
That oil line has a quick connect fitting and it does require a special tool to remove however it is not difficult to release the connector using an improvised tool that will push the black ring into the connector to release the spring clip. The connector has a tendency to stick and requires a little force to separate it. I use a prybar to do so.
You can get a look at the tool (or buy) it HERE
but it is a little pricey if you are going to use it once. Looking at it might help you fabricate something.
To complete a head gasket repair you need to correct the cause of the excessive combustion chamber pressures. Check your turbocharger as it may be causing an over boost condition and have your PCM updated to a current level calibration which will mitigate over boosting.
