Compression Check

How much should a normal 3.1 have? might have bad head gasket, got that tickin sound and antifreeze is brown, and its not the mixture of the green and orange ha

It needs to be over 100, but some people get between 150-180. The biggest thing to look for is consistency between cylinders. You want all cylinders to be within 5-10% of each other.
