Yes it could be but you should be getting oil in to the chamber also check your tail pipe if you have white smoke coming out that is oil if it is black that is to much fuel if you are getting alot of water then you definetlty have a bad head gasket you will get some water that is condensation built up in side the muffler but that should burn off quick have somebody hit the gas pedal while you watch the tail pipe if it starts blowing water then it is without doubt good luck hope for the best but prepare for the worst let me know if you need more help

Is the motor blown if there is water in the spark plugs and it smells burnt

The motor isn't blown but you have a defective or blown head gasket. A garage can test with a coolant pressure tester. You will often see your water level going down. If you remove the oil filler, look for a creamy deposit like mayonnaise on the cap. Pull the dipstick and see if you see droplet of water, or the oil is milky.

White smoke just started coming out the exhaust. It smells like gas, not coolant. What could it be?

Has the vehicle been overheating or losing coolant? The symptoms you describe could point towards head gasket trouble (and other faults). Often, the exhaust fumes from a car with a failing head gasket will smell 'pungent' and 'sharp'.

Check the oil on your dipstick. If there's a greyish/cream sludge - sometimes referred to as 'mayonnaise' - this points towards coolant entering the oil system via a leaking head/head gasket.

Also check your coolant - is there any evidence of engine oil in it? Although the mayonnaise on the dipstick is usually the tell-tale sign of gasket problems.

If you suspect the head/head gasket try a special sealant such as:

My 1994 chevy camero I fill it with coolent 15 mins of driving it , I open the cap and the coolent is low , and it's not leaking on the ground so I fill it up again and the same thing happins again

You may have a blown head gasket. Pull out the engine oil dipstick and check the color of the oil. If it is black / honey color, that's OK. If your head gasket is blown into the water jacket, there will be oil in the sump, and the oil on your dipstick will be a greyish color.
Another check is to open the radiator cap (the one on the radiator, not the one on the plastic filler bottle) and start the engine. Now look into the open radiator and rev the engine slighly. You might see gas bubbles in the water, indicating a compression leak to the water jacket. Also a smell of burnt gas coming from the radiator indicates the same thing.
Let us know if this helps, so we can check other options.

I have a 1995 grand jeep cheerokee and my thermastat gage isnt reading and my oil smells like gas how much is new injecters and how do i keep my jeep the coolest as possible

If it has been a long time since your oil has been changed, the fuel smell is somewhat normal. Changing your oil and filter will take care of that. Unless you are having problems with the fuel injectors, there is no need to replace them. They have nothing to do with the fuel smell of the oil. If you feel you need new injectors, they will cost around $50.00 each. Your temperature guage will probably work if you replace the Coolant Temperature Sending Unit, cost is about $10.00 for the 6 cylinder engine. If, by keeping your Jeep the coolest possible, you mean the engine temperature, then maintaining and servicing the cooling system regularly will be all that is needed. Change the thermostat, drain and flush the cooling system and add the recommended quantity of a 50/50 solution of antifreeze and water. If you have an electric cooling fan, make sure it is operating properly.

1994 Ford Mustang blowing white smoke that smells like pure gas. Gas running straight through and getting about 5 mile per gallon.

Sounds like a blown head or intake gasket. Coolant in the oil is a sure sign. Another sure sign is loss of coolant with no obvious leaks.

Coolant in the cylinders will emit white smoke, and the fuel smell is probably raw fuel passing through because it can't ignite due to the coolant.

Pull the dipstick and if the oil looks milky, then it is a blown gasket, or worst case scenario, a cracked head or block.

28 Solutions for ''HOw can I tell if I have a cracked head blown head gasket or cracked blown like how can I see it''

Often (but not always), a blown head gasket will also cause deposit of water on a piece of cardboard held an inch from the tailpipe output while the engine is running (when this is happening, it is likely that the catalytic converter has been ruined and the muffler will corrode in short order as well).

Sometimes drops of water will be seen dropping from the end of the tailpipe. Another clue: turn on the heater; often when the head gasket is blown an odor of antifreeze and synthetic rubber will emanate from the heater vents.
Many of the symptoms of blown head gasket can be caused by some other problem in the cooling system, without the head gasket being damaged. Conversely, other problems with the cooling system can cause a blown head gasket and/or warped head.

When checking for a blown head gasket, one of the most common tell-tale signs is a milky-gray ring around your oil cap. When coolant enters the engine oil through a crack in the head or through a blown gasket, it evaporates and leaves a milky ring around the oil cap. Another easy way to tell is to check your oil dipstick. Change your oil and pull out the dipstick. Make sure that you take note of how far up the dipstick the oil is. Top off your cooling system and fill your cooling reservoir to the top. Screw radiator cap back on and start engine. Run engine for about 20-30 mins. or until it reaches normal operating temperature. Allow engine to cool (engine must cool completely to get accurate oil reading!!). Check oil dipstick again. If the oil has a watery appearance and has risen noticeably up the dipstick, the you probably have a blown head gasket or a warped head. Also look for a dripping, sweet-smelling liquid coming out of your tailpipe. Any of the above symptoms could be the result of a blown head gasket. The easiest way to tell is with a compression meter. This replaces the spark plug and lets you know what compression each cylinder is running at. If your compression is abnormally low, then you have a blown head gasket or a warped head. (note: consult repair manual for appropriate compression of each cylinder.)

Adjust fan belt 1990 jeep cheerokee

No diagrams available, but under the power steering pump, over on the right of the motor looking toward the back, there is a bolt 12mm head to the right. It is the tensioner bolt. Loosen the 2 bolts at the very back of the pump, and I think 2 through the pully. It should be easy then.
