If I crank the engine with the radiator cover open water will fly out like there is no tomorrow, my car overheats and I have to add water several times a day.. sounds like a head gasket to me.
The premise is that you make sure there is no air in the system first, you see - but even it there is air in the system and only one of the cylinders (when plugged) disturbs the water, the results are valid, even without checking for hydrocarbons. The water didn't move with any other cylinder plugged except the guilty one.
This method will only show positive results if the problem is the head gasket. But this type of failure doesn't migrate coolant into the cylinder, it migrates compression into the coolant. And if coolant is only making its way into just one cylinder, the problem isn't likely to be the intake manifold. Sometimes exploratory surgery is necessary, even in a shop environment. Pull the intake and see what you see. Inspect the gasket.
Using this or a similar test -- for example, pressurizing the cooling system with the plugs removed, and then, after 20 minutes, cranking the enginne to see if antifreeze is present in one of the cyllinders -- if you get a POSITIVE diagnosis how can you tell whether coming from the head gaskets or the intake manifold? I'm trying to answer that question with my own problem, a 4.6 liter Ford V8 with a mysterious coolant loss. Is there a way to narrow it down to one or the other?
Well, that's not a bad idea, I don't suppose but the guy who owns the car we fixed is still driving it - and none of the old ones had air conditioning, which is pretty important...LOL
@thecurioussoul88 There could be more damage than just the head gasket. The head could be warped, which means you'll have to get it straightened/resurfaced. You'll probably have to get a valve job done as well if it's warped, as usually the valves don't seal very well after that. Of course there could also be a cracked head/block/piston, so the cost of the job can just keep going up, so you won't know the total cost until the job has been started and the engine is apart.
@McCuistian I bought my sister a 2000 muastang V6 for her 16th birthday, and there's water leaking not from the radiator or hoses, but from what looks like the engine block itself. It's leaking astraight across from the driver's side all the way across to the passsenger side. I can't find any oil in the coolant, or vice versa, so can it still be a head gasket.
@kelvinfeliciano Thanks for the quick response! lol (just kidding) It ended up being the water pump, but thanks anyway. The water was just running along under the head so it looked like the water was coming from somewhere else.
ya know...you really didnt have to take the spark plugs out. As a matter of fact I think it would have been a better test if you left them in. With the spark plugs in this would give a lot more psi thus better results. I have seen many people get burned by diagnosing a head gasket by watching bubbles. Many cars will show bubbles w/o any problems. I don't doubt that this head gasket is bad but a lot of people will watch this clip thinking that bubbles mean head gasket.
Nobody else had a problem hearing what I was saying - but it isn't rocket science. Start with a full cooling system and the cap off. Start with all but one plug removed. Spin the engine.. see if the water is disturbed. If it isn't move the plug to the next hole and try again. If the water is disturbed with the plug in, say, cylinder 3, then you have a blown gasket in that cylinder
yes, got to have that t-stat out or the test won't work - because t-stat will be closed on a cool car, sealing the engine water jacket from the radiator.

You can do it with the original coolant - but usually if it's overheating the coolant has been pushed out. We were using water so as not to waste coolant
this begs the question, can't you just do this test with the original coolant in it? are you just using water because you don't want coolant all over your engine?
Thank you for the video. I believe I am leaking oil from my head gasket, is this possible? I am leaking no radiator fluid. If I were to seal the Block from the outside with.. ? Magic.. sealer.. :/ stuff... that prolly does not exist.. would that fix it? Or do I have to do the head no matter what?
hey guys i drive a 97 ford crown vic. when ever im holding the brake down lets say at a stoplight the car rumble a bit. the last spark plug next to the antifreeze is wet......could that be the problem?
If you add a couple of squirts of engine oil to the cylinder and recheck the compression you can generally tell. If the piston rings are causing the low compression it will rise significantly after adding oil to that cylinder. If not, it's a valve problem. You might still have stuck oil rings, which wouldn't affect compression but could cause the engine to use oil and smoke.
@Naturalhit do a dry compression test followed by a wet compression test,Use a cap of motor oil and dump it in the cylinder,If the compression jumps up after doing the wet test its posotive the piston rings are shot,Be sure to disable the fuel system and ignition,Good luck.
@McCuistian well if its blue its oil burning but u wouldnt see bubles.( Grey smoke or better to say steam its head gasket) if its black u need a tuneup.

What if that were air in the cooling system that didnt get bled out after maybe a water pump job or....? Better to ck for hydrocarbons.

I'd be checking the intake gasket - is it leaking from underneath the middle of the engine on both sides or running down both sides in the back?

@Naturalhit well since its just cylinder #1, i think its probably that either the head gasket is failing or the ring is stuffed.

Not necessarily - there are several ways a head gasket can blow - if combustion is moving into the water it won't smoke at all.
