Head gaskets or HPOP

I have another thread going right now with the inspection of my HPOP system. The background of the story is I have a no start issue. Truck was running fine then all of the sudden wont start. I have already tore into the HPOP system and kind of suspect a HPOP failure as I am seeing gold flakes in the oil. However, I know for a fact the head gaskets are not great as it pukes coolant out the degas bottle. Before I tore everything apart I tried spraying starting fluid into the intake and it wouldnt even fire off that. I am starting to think my head gaskets could be completely done now. If the HPOP was dead shouldn't the truck still fire off starting fluid?

Starting fluid is a big nono in the 6.0, but I would say you are correct in your thinking about it not starting witht eh starting fluid. If you do want to use that stuff, make sure you let it sit in the intake for a few seconds before cranking it over, so's not to get a huge explosion in the cylinders

Have you checked the FICM? Those flakes could be many things, but definitely NOT good in any case

Its more like gold glitter than gold flakes. I tested the FICM before I did anything. That checked out well. I also tested the voltage at the ICP and it would only build 300 psi at crank. That is why I headed down the road of HPOP.

You could have a HPO leak too. What year is the truck? The 03' and early 04's had a bad run with HPOP's

Do you know the build date? Does the HPOP look like an aluminum housing, or cast iron?

Not sure of the build date but the HPOP housing is definitely aluminum. I can check build date when I get home.

If it's aluminum, it's the newer style HPOP. Not many failures from them, but it does happen

Lots of info here 6.0L Bible Table of Contents

You def have something failing, or failed though, with the glitter in the oil. I would change the oil every 2k for a couple oil changes so that stuff can get cleaned out quickly, before taking out injectors

Maybe send a sampe of the oil to Blackstone for a report on the metals that in there. It could be other bearings, but I'm not sure it can point you directly at a certain bearing. The only time I saw that stuff in the oil, the main bearings were toast
