Good morning - Have an HD6 with the HD-344 engine. Any tips on what to look for when the head gasket goes? I'm consuming coolant and have "no leaks" that im aware of.

If so, any tips on head removal that may not be obvious?

Check the oil in motor if coolant is mixe with oil or loosed the drain plug if water is coming
