Yea the 7m is a fan of Blown head gaskets do to the torque specs

75 for bolts, 90 for studs. 4 or 5 passes is what I do. If well lubed and the threads thoroughly chased 5 will make sure torque is more consistent across the head. Remember though, the greater the number of passes you make the more likely you are to have problems with striction and thus irregular torque readings.

here are some before pictures that i'm trying to figure out what it means about my 5th piston its the only one without any corrosion on it at all and this car has over 200k miles on it.
any ideas

Yea I was in the junk yard and seen a supra with no head and two pistons looked new and the other were black like they had them to replaced or something

Generally that means it's been steam cleaned by a leak in the head gasket in one of the coolant jackets surrounding that cylinder.

so most likely that was the piston that had the head gasket leak?
any good tips on how to clean my gasket area and pistons. I'm gonna use a buffer brush and all but wanted to know if anyone had any other suggestions?
