Noticed some oil in my nice, clean, new coolant... Fuck.

This can't be headgasket, it would be the opposite. It's probably a cracked head from over-revving it or something. I jump on the G35 and head over to Subaru and picked up their "coolant conditioner", then went to Napa and picked more Zerex asian coolant, then Walmart to get distilled water so I can water down the new coolant mix.

I changed the oil and coolant but this time I mixed the coolant with a little bottle of Subaru coolant conditioner, I've put about 5000 miles on it and no problems! it runs at 186*F, coolant and oil are clean as a whizzle.

I'm gonna retire it from track duty though...
