Jeep grand Cherokee 3.6 petrol Misfire

There is a semi common fault with the 3.6 petrol engine fitted to the grand cherokee and some wranglers. The common fault is the engine develops a misfire from Cylinder 2 caused by low compression.

This fault is a damaged valve which requires the engine to be stripped down and some very significant costs involved.
