Is this 100% condensation, or can it be caused by a leaky head gasket? There is a huge arguement on youtube about this and i wanted to see what you all thought about it! There is white smoke coming out of the exhause when he revvs the engine up, and when he unbolts the exhaust, alot of black liquid comes out of the pipe…its a kid that owns the car (looking for a deep “throaty” sound) and likes to revv lol

Some water out of the exhaust is normal…. If it is a leaky head gasket, a way to tell is look for loss of coolant… As you know white smoke is indicative of coolant burning… But a smoke on revving (on a warm engine) is indicative of oil burning past the rings….(generally blue smoke)…. Black liquid in pipes…hmmm think about it…. A compression test with a wet test would confirm ring problems…. Fuel burning off is generally black…. A sniff of the exhaust may be a clue as well… Sweet is coolant, oil is well… burning oil smell…. Stinky is either cat or can be fuel caused by a leaky fuel injector…
About an hour diagnosis time starting with a pressure test of the cooling system, compression test (with wet test) would probably tell you what is going on here…
