I have an 03. 6.0 F350 XLT. I’ve done the complete bullet proofing over 10 years ago including FICM repairs upgrade. I have coolant leaking, small leak, around the passengers side starter area. I’m praying it’s not my head gasket. I did the uv dye and a coolant psi test and finally found the leak. I see coolant around the passengers side rear exhaust area, but it may be leaking above it….but I’m not sure. I’m wondering where else it could be leaking from? From the top of the engine, I see no leaks by using the uv light.

If it is my head gasket, I have not found the procedure to lash the rocker arms into position when looking for cylinder head installation on YouTube.

does anyone know what the process is to properly lash the valves on the 6.0? And how do you find top dead center on the 6.0 engine?
I’ve rebuilt plenty of engines and know that most follow the sequence of the firing order. I’m looking for the sequence to lash the valves.

any help is greatly appreciated!
