I was at my friends house today and he put some very diluted gas into my gas tank. I didnt know until he told me to smell it and confirm it was gas after he put it in and as soon as I smelled it I knew I was gonna have some problems.
I was driving down the road and it just started losing power, spuddering and turned off. Does anyone know the extent of the damage that could have been done or how much it would cost to repair this problem? Oh ya, it was like 3 quarters of a gallon that he poured into my baby and it is a 94 deville with the 4.9

Water is the worst possible thing you can get into an engine in large amounts. If its not enough to seize the engine, you should be ok as long as it was evaporated in the combustion cycle. The problem with water is that it is un-compressible and can cause damage to engine parts when compressed enough. But if your engine is not seized you're probably ok.


Be forewarned though, my dad got enough water in the cylinders of his Fiat 124, and that engine never made another sound again. I'd never get gas from that friend again. :nono:

If it is in the gas tank, you are not going to hydrolock the motor. Do you know what exactly he put in the tank?

3 quarts of what diluted with what ??? Water and gas DO NOT mix unless there's a staggering amount of ethanol or methanol included, so whatever he poured in was not diluted.

I'm pretty sure it was very diluted gas, diluted with water but I dont know exactly how much water to gas but it will not start. I tried to put fresh gas and crank it through the motor but I may have burned up the starter because it wont do anything know and the battery has a full charge.

It could have been bad gas. But it smelled like really weak gas or watered down gas it was very clear also. wat if water got into a gas can would the water float or sink.

Problem is that gas floats on water, so if there's enough water in the tank to submerge the fuel pickup screen, you're SOL. Now you have to use a hand vacuum pump to try and get to the bottom of the tank sump and remove the water. After that drill, you'll need to purge the fuel system of water, because the engine will NEVER run with water in the lines......the injectors (?) will not pass solid water.

You have a professional mechanic's problem on your hands.

Your "friend" owes you a bundle of money. Plus, he needs a brain overhaul. (Jack up his hair and run a new human underneath.........)

Oh hell ya hes payin for it if it can be fixed I'm just tryin to get some facts for peace of mind and see if I can get some idea of how much this is gonna cost and the damage done. As for the friend he use to be my best friend and then one day he just went schizophrenic and that shit makes a smart people seem stupid.
I just visit this guy every know and then just happened to **** up my car in the 5 min I was there after like 8 months.

IF if twas water, you can dry it up with a product called Iso-Heet. It is real cheap because it is 99% Isopropyl Alcohol. You can also get the 99% Isopropyl at the drug store just plain even a little cheaper. Put it in your gas tank and it will absorb 5 times it's weight in water removing it from your gasoline. I comes in 12 oz. red colored long-neck bottle. I'd use a couple IIWU.

Is there any hope that some methyl hydrate might help,or is this more
than a bit of condensation problem?.

There is prolly a good bit of water in the tank. I'm pretty sure I'm gonna have to get it worked on.

My question is why did he have watered down gas in the first place? How did he get water in a gas can? IF it is water, get the alcohol that Amen mentioned and put some in the tank. IF it is water that should get you going AFTER you get it pumped through the system.

You may be hydrolocked already. maybe check your dipstick and see if you can spot any water in the oil. I think you can relieve a hydrolock by taking out the spark plugs or draining the oil

The gas can was outside probably all winter He said it was for mowing the grass. Sub said that the water wouldent pass through the injectors.
Could I still get hydralock from this? Or can water pass through the injectors?

How can you tell if you have hydralock?

Whatever it is, apparently water, it has already passed through your injectors since that is the only path available to enter into your combustion chamber. As we all know water doen't ignite very good. Thats' why the car could be hydrolocked. The fuel pump pumps. It has no brain to say, OOPS! that's water, I'm not gonna pump that stuff up into the engine. I mean unless I'm missing something here.

When you turn the key do you hear the starter make any noise like it is trying to turn the engine. You should hear a clunk as the pinion gear on the starter meshes with the flex plate on the engine. If you hear that clunk then that means the engine is seized, or hydrolocked as it may be in your case. If the starter does nothing at all it is most likely electrical. Start by checking the fuses.

Yes, dirt-cheap has it right. BTW, hydolock means that enough of a non-combustible substance, usually water, has entered the cylinder on the intake cycle(s) to the point where on the compression stroke, there is no ignition. The crankshaft is then stopped dead in it's tracks and the engine is Locked in that position until the non-combustible condition/substance is removed- the sooner the better, I might ad. Time is of the essence. that's why the alcohol treatment could be rather urgent. It wouldn't hurt to pour a little down your throttle body at this point.

Relax, there is no chance of hydrolocking the engine via water in the tank. Granted it will not combust, but it is only a mist being sprayed into the cylinder and will be passed out the exhaust valve on the exhaust stroke.

THAT is far more likely to hydrolock the engine.
