I'm assuming this is where all the gasses were getting into the coolant.
Also...does anyone know of a good product to clean the head gasket surfaces with? I gently rubbed it with steel wool soaked in brake cleaner. I spent forever cleaning the little steel wool remnants.
Fun project! Way better than the track. Glad to see someone else writhing in pain.
Looking at your pics, it seems pretty obvious where the HG failed, so this is most likely irrelevant.
BUT this one time, I had a very mild HG failure, and the amount of coolant getting into the crankcase was tough to detect. I.E. no tell-tale signs of mixing. It wasn't until I sent an oil sample to Blackstone that my fears were confirmed. See the data from sample date 1/5/19 (this report is actually from a more recent sample, but the old data is there too). Oil still looked, felt, smelled, tasted "normal"...I was ready to take the Pepsi challenge. But the UOA tells all. Since the previous report, Potassium and Sodium were WAYYY up.
My starter is sticking and i want to changer the upper radiator hose, so maybe it makes sense to remove it to do the other jobs
It wasn't bad at all. I think it was off within 30-45mins.
I strongly suggest being patient and removing (properly) anything that gets in the way. Don't shove the wrench past a sensor or try to muscle stuff off or try to work around stuff and end up breaking it.
Use cunning.
Don't damage the heater hoses. Because (you guessed it!) they're on backorder/discontinued status. And it doesn't seem like there's too many aftermarket rubber (not silicone) offerings. At least not for 06+

Where did yours fail? My oil also had no visible traces of coolant mixing. I really think the leak was isolated to the combustion chamber/coolant passage.
It didn't seem to be leaking coolant into the chamber either. Only allowing pressurized combustion air into the coolant.

I believe it's a 2-3 week backorder right now if you order directly from Japan. My buddy's shop has been gathering parts for a head rebuild on my car and just called me today to let me know about the hoses. I'm tempted to just continue to use my original ones so I can get back to driving sooner
