Usually if it's blown between the cylinders it will have white steam out of the tail pipe. If it's crack between the oil and coolant gasket holes, you will have coolant entering the crankcase and your oil will have brownish sludge. Look for signs of coolant mixing with oil on your dipstick.

to be honest it not as easy as it sounds to line them both up,,,,you may need to use a locking stud to do this,, and i have seen engines that just wont line up even to half a tooth out,,, but they run just fine anyhow, its all down to just how good the pullys were cut and marked

Water at the tailpipe is nothing to "sweat" about.... it is normal for just about any car made in at least this century!

If you have a blown head gasket the only option you have is to replace the head gasket.Also take your oil pan off and clean as much of the gunk as you can out of it.When you take the motor apart you want to make sure that you clean the parts so there free of any grime on both the top end and the bottom end.When you put it back together iI recommend that you run engine flush through the motor to clean any residual sludge.Hopefully this will help clean the oil ports in the bearings of any sludge.I would flush it at least 2 times and then put oil in it.Change the oil after 2000 miles and then change it every 3000 miles.Just remember you must make sure that you clean the motor real good before putting it back together.You could save yourself any future problems by also replacing the connecting rod bearings.

There is water in the oil. I don't know if it is a blown head gasket or blown head


You can't tell untill you get it apart. and then some times you still can't see a crack. It needs to go to a machine shop to be checked. I send them all out to be checked when I do a head gasket replacement.

How do i tell if i have blown head gasket


The signs for a blown head gasket are:
1 - The car oveheats above 195F.
2 - The cooling system is loosing coolant, low coolant level.
3 - The coolant start boiling and owerfloing from the coolant bootle.
4 - Mixture of coolant in oil, or oil in coolant.
5 - White smoke from the tail pipe.
The diagnoses to reveal a blown gasket are.
1 - Radiator compression test. Can be done at any car reapair shop for $30.
2 - Static cylinder compression test. Can reveal at which cylinder is the blown gasket (pression low, or zero). This is very important at V6 or V8 engines.

1996 vw jetta leaking oil and i believe also water from the top of the oil filter housing on a form of sort of bubbles or foam..is it possible to fix it by just replacing a gasket or something else?


Seems you have a blown head gasket. To replace a blown head gasket, the cylinder head must be removed from the engine. Once the head is off, the mating surfaces of both the head and block should be inspected for flatness as well as any damage that might have contributed to the gasket's failure or might prevent a new gasket from sealing properly. If the head is warped, it will not seal the new gasket properly and sooner or later it will again fail. Resurfacing and/or straightening the head may be necessary. An inspection of the head may also reveal cracks or other damage that will have to be repaired before it can go back on your engine.

How do i tell if the heads creaked on a 91 celica


a cracked head or blown head gasket,will cause your vehicle to have a miss in the cylander where the crack is or where the gasket is blown. you can also see coolant leaking if the gasket is blown. you can also see water in the oil,and white smoke come from the exhaust.
to tell for sure that the head is cracked,and not just a blown gasket is to remove the head. you will instantly see if the gasket is blown. if its not,then turn the head upside down and look at the small space between the valves,as this is where 99% of cracks occur.

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.)

Losing Coolant


You may very well have an internal leak as in a blown head gasket. If you see white smoke from the exhaust and it smells sweet that is a definate sign you do. You may also notice a white foam on the underside of the oil cap and the oil level may be over full. Remove the radiator cap, engine cold, and start the engine. If you see air bubbles escaping you have a blown head gasket or cracked head. Stop driving the car until you verify this with a compression test. Severe engine damage will occur if you continue to drive this car, if the head gasket is blown.
