Hi, I'm Jason Halsey. Welcome to Plano Diesel. In this short video, we're going to take you through the basic steps of head-studding a Ford 6-liter power stroke engine. So the main fatal flaw on this 6-liter motor is heads separating from blocks. The head is held to the block originally from the factory with this head bolt. This head bolt actually stretches under extreme conditions and can cause cylinder pressure to escape and go out and allow coolant from these coolant holes into the cylinder causing the engine to hydrolock. So this is the head gasket. The head gasket sits between the engine block and the cylinder head. You can see here these guys are all rusty because this engine got hot and coolant got into the cylinders and caused the engine to hydrolock. These head-studs do not stretch. And so when they're in here, the cylinder head is securely clamped on top of the block. So when these head bolts that come from the factory don't stay strong and stout, this head actually separates causing a gap. So when the head separates from the block, it causes the piston to push all the compression out the sides and the engine will no longer run when it doesn't make any compression. A couple hours into this project and we're making some pretty good progress here. We've gotten the radiator, the fan shroud, and the fan out of the way to free up some working space. Even though removing the cab is not even in the Ford service manual, it has become popular when working on these six-liter motors. Per the Ford manual, we stud these motors with a cab in place, saving time and money. Blue paper towels are stuffed in the intake ports into the cylinder heads to keep dirt from getting down in there. We use an engine hoist to remove the cylinder heads once they're disconnected. These babies weigh about a hundred pounds per side. Save your back. Before, blown out head gasket, nasty and dirty. After, a little elbow grease gets it nice and clean. With the new head studs and head gaskets in place, we'ready to put this baby back together and fire her up. Let'see how she sounds.
