1. Exhaust: When you have a gasket leak, you will notice white smoke coming out of your tailpipe. Sometimes drops of water will drop from the end of the tailpipe. The exhaust will also have a sweet smell to it.

2. Spark Plugs: Your spark plugs will display one of the last signs of a blown head gasket. If you have green dyed coolant in your system, the spark plugs will have a green tint around them. If the problem is very severe, the coolant may start squirting out of the plug holes which is not good.
3. Oil: You will notice a milky type ring surrounding your oil cap. This is caused by coolant entering the engine oil through the leaking gasket. This mixture leaves the milky type ring around the oil cap when it evaporates. You can check for this by taking the car for a short drive, then checking the oil for contamination.

4. Engine: Lack of engine power is a sign of a blown head gasket. The engine will lack power due to compression loss. The engine will also run poorly and will idle roughly. You should also be careful because the engine will overheat quickly when you have a blown head gasket.

5. Bubbles: A gasket leak will cause bubbles of air to come into your radiator. To check for this, you should first remove the radiator cap then warm up the engine. When you rev the engine, you will see bubbles come out from the top of the radiator.

Hope this helps, best regards, Happy Holidays!

SOURCE: blown head gasket

I would change both, as well as use new head bolts. Make sure your heads are not warped or cracked, especially the one that is leaking. There may not be any need to change the head if it is not cracked. These are prone to blowing a gasket especially after 150K miles or so. It will not cost a huge additional amount to change both head gaskets since the engine will have to be disassembled down to the heads anyway. Hope this helps you, Rick

SOURCE: 1994 old cutlass ciera 3100 blown head gasket.

Get a Chilton's book on the car. It will take you thru the whole job, and give you the torque specs for putting it back together. You will need a torque wrench, foot pounds, and a good socket set.

Signs blown head gasket

Hi there:
Pay attention. here is the most common symptoms a Blown Head Gasket are:
- Your car is overheating. You know it's not the Fan or Thermostat.
- White Smoke is coming out of the tail-pipe and it smells like Anti-Freeze being cooked.
- The car won't start:
* You have already verified it's not an Ignition System problem because you have Spark coming out at all of the Spark Plug Wires.
* You know it's not a Lack of Fuel, because you have verified that the Fuel Pump is delivering Fuel to the Fuel Injectors.
- The Engine Oil is thick and tan to off-white color.



Hope this helps.

Engine management light stays on

check whether you do have a smell of fuel or burnt gasket in the radiator after remove the cap. If so then you have an overheated engine and blown gasket. Or check whether if you have either water in engine oil or vice versa. Having any of the two,surely you have to remove cylinder head for renewing cylinder head gasket etc.

1994 Pontiac Sunbird was driven for three months without coolant until it overheated a day ago. It overheated on the way home and started smoking out of the air vents. That night, I filled it with...

i assume the shop was talking about heater core being bad and even if heater core is bad they should be able to test for a head gasket being bad actually you can totally bypass the heater core so there no reason to fix that before you check for a head gasket being bad
and if you have run for three months without coolant you will be extremely lucky if the head gasket not blown or head or block cracked
i would do nothing about the heater until car is checked for blown head gasket
honestly i would take the car some where else because they are either trying to screw u or have no idea of what there doing

Engine runs rough also how can you check to see whether if i have a blown head gasket. it also has no fans running to cool the coolant

Sounds like the overheating condition has blown the head gasket, if compression or oil/antifreeze mixing is evident.

Running an engine with no fan to cool the radiator is a common cause of blown head gaskets. yes.

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.)
