wait so u r sayin i have a blown head gasket if its in the coolant?
I is very possible that you could have a leak from an oil passage into the coolant through a head gasket even if you don't have water in your oil.
How does the engine run? Have you lost compression? Even if it'* running well and you have compression, if you caught it early, it could be just the start of bad gasket with a small oil leak into the coolant.
Be prepared to go all the way to the heads, if you start the job yourself. It'* not that much more work to take off the heads once everything else is stripped off. It all just takes time. Better you spend the time with your own cheap labour, than fork over big bucks for a dealer to do.
I will give you a chance to clean things up and maybe even upgrade while you're at it.
