    Don't do it. If you need to ask then it is way over your head. The Northstar engine has a fairly complex timiing chain setup for one thing and second, the northstar engine is known to have the head bolt threads pull from the engine block which causes head gasket failure which I suspect has happened to your engine. The threads are repairable BUT you must have the proper thread repair kit made just for the Northstar engines.

    Have an Experience Mechanic do the repair for you, AND MAKE SURE that they have worked on the Northstar engine before.

    Safe yourself some grief !

    I would suggest you don't do it !! One thing leads to another on those. How many miles? etc. would play into the decision also. Good Luck!! ?:)z

    If you need to ask, Don't Do It!! It's MAJOR WORK which is why it's big $$$ to repair.
