2004 Blown Motor Replacement Help
Hey guys,
I am looking for some help/advise on my motor swap. I blew the motor in my truck a couple weeks ago (5.4L Triton). She froze solid going down the HWY pulling my boat. I purchased a motor from a wrecking yard with~ 70k miles on it. I decided to do the swap myself and have run into a dilemma. In order to un-mate the trans from the motor the torque converter nuts need to be removed. There is an access port where you access the nuts one at a time. You must roll the engine over to bring each nut into view. This is where I am stuck. The motor is seized solid and will not turn over by hand even with a socket and a cheater bar on the main crank pulley. I have no idea what to do. Have any of you guys done this before??? Any good advice for moving forward? Do I need to remove the oil pan and/or the heads to figure out how it's stuck (pretty sure it ate a valve)? Any help would be greatly appreciated!!! <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

If you have access to a lift I would lift the cab and pull the torque converter out with the engine. I made a post in another thread describing the cab lift process, it's not hard and you will prob have it in the air in 2 hours the first time. Otherwise, you need to pull the pan and some rod caps to get the engine to turn.
