Hi Guys
traded a pretty clean crew cab frontier for some labor, 1st symptom was struggling to turn over... when it did it blew ALOT of water vapor out of the tail pipe. I figured water was getting into the block how to diagnose if its the head gasket or can the water pump fail and let water in
Thanks in advance !

you will have to do a leak down test via radiator. you put an air pump with a pressure gauge on radiator neck and pressurized system according to instuctions, let it sit overnight to see if pressure drops. if no visible external leaks present, you might have a blown head gasket or a cracked head.

sounds like a blown head gasket or a cracked head. do the leakdown test. it will tell you a lot more of what you need to do. they make a stuff call bar leak for blown head gaskets. but that is a last ditch effort and should only be used on high mileage veihcles not worth putting much money in, it will stop your heater core up too. best to taje to a mechanic you trust for leakdown test. you can pull the plugs and see which one looks abnormal to see which side is throwing the fit.

Water is a normal product of the combustion process - make sure it's not just typical water upon start up, when the exhaust system has not yet had a chance to warm up.

Is there pure water or antifreeze in the engine? Assuming it has coolant in it as it should, then the engine could only leak coolant into the exhaust, not water. A bad water pump can cause an engine to overheat, not cause coolant to get to the exhaust; only a failed intake or head gasket or a cracked block or cylinder head can do that. If all you're seeing is water, than I'm with Cusser in that you are just looking at combustion process by-product. Also, coolant getting to the exhaust will have a bittersweet odor to it; there's no mistaking the smell of coolant burning!
