Help settle an argument, head gasket?
Help settle an argument, head gasket? Two friends of mine who are also fbody fans, are arguing the cause for engine coolant overflowing from the coolant overflow tank and making a puddle under the passenger front tire. The car is a lt1 camaro. Myself along with my other friend thought it would be the head gasket no problem. The other guy disagrees but can't exactly elaborate 
Is there ANYTHING else that would cause this? My understanding is the car in question was left idling, turned off then it over flowed out the coolant overflow tank? not much but still. Besides that the car does run fine, doesn't over heat or smoke according to the story i heard. Rad cap, cooling system pressure, anything else that could cause this? Sorry is this is all jumbled up.

Yes, but right from the overflow cap, right over the top being pushed out.
I guess it depends at what temp your car is overflowing.
If you had a blown head gasket (or a bad waterpump, or any number of other issues)
and your cooling system was overheating, it would pop a good radiator cap and spill out the overflow.
If this is happening at normal operating temps, it could be the cap.
You could always do a pressure test ... but caps are cheap.

Verdad Gallardo THE DEBATE CONTINUES, opinions please. Today to further investigate we drained my friends oil. Now i know the quality isn't great but photo's provided. To me this looks milky, but then again maybe just worn out oil? The cap was replaced and temp is fine, no over flow either. Also the oil cap was SPOTLESS, no residue there. There would be other signs if the gasket blew correct? possibly just not driving the car long enough on trips?
The bubbles aren't a good sign either. Agitate it with your finger and if you see bubbles or if it behaves like coolant/water, then it's coolant/water.
What you can do is rent a coolant pressure tester at any parts store. Pressurize the system and note if pressure is lost quickly. Take all spark plugs out to do this. If system keeps pressure then leave system pressurized (no more than 18psi). After awhile hand crank the engine and see if coolant spills out of any spark plug holes.
