Has anyone ever heard of having to drop the engine to change head gaskets in a 4.6 Northstar engine? It's in a 1999 Cadillac Deville. I've always known head gaskets to be accessible by taking apart the engine from the top down, but I've never done a Northstar. (The car is not mine and I do know how notorious Northstars are for head gaskets so don't leave any smart comments.) Thanks.Changing head gaskets?
Yes you have to drop engine , just as easy you might as well drop all the way, the timechain cover takes up complete side of engine and if you really have head gasket problem then you most likely have broken headbolts or stripped out head bolt holes in block, real big projectChanging head gaskets?
Here are the instructions from Aotozone.com. http://www.autozone.com/addVehicleId,2525301/initialAction,repairGuide/shopping/repairGuide.htm?pageId=0900c152800a57fd
They do not say anything about removing engine. Good luck.Changing head gaskets?
Yes, you should drop the engine cradle and all.Changing head gaskets?
You don't have to,but if you ever got the chance to do head gaskets in the car,nows the time.I recommend leaving it to the professionals.At my dealership,we have a special cradle with caster wheels to remove the front subframe,engine,trans, as a unit which holds the engine at the right height to work on it.Also,if your going to waste your money on a northstar,you should have the bottom end resealed because they all leak oil.
