How can i tell if i have a blown head gasket and is there a difference in cracked\warped head or blown gasket when diagnosing?

If you are getting compression into the cooling system you either have a blown head gasket, warped or cracked head, or cracked cylinder wall. You need to find a reputable professional to properly diagnose your issue.

Blown head gasket ,try head gasket fix.

You are probably right as all codes refer to misfire in cylinders.. have a compression test done to check for blown head gasket and cracked/warped head and have a cooling pressure test done also to show cracked head and other than head gasket.

Have a coolant pressure test done and compression test done. There is a real possibility of a cracked head but you may be lucky with just a warped head and blown gasket.

Water in the oil means one of 3 things:

1) Cracked or warped cylinder head
2) Cracked engine block
3) Blown head gasket

Blown head gasket is the best you can hope for. And cracked or warped cylinder head is next most likely. A cracked engine block is least likely of the three. Have you noticed anything unusual, heard any noises? And has the car overheated really badly?

If it's drivable ask if you can take it & HAVE an independent inspection done. It can be bad head gasket, and head (cracked), cracked block and many other things. In any case, hope you're getting it cheap because it's going to be expensive to repair.

There is really no difference between a blown or cracked head gasket. In either case the gasket would have to be replaced. Generally the term "cracked" is used when referring specifically to the cylinder head/s its/them selves. If the cylinder head is cracked it is a much more expensive repair.

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.)

I have yet to see a cracked head on a 22R,so more than likely a blown head gasket,unless you overheated and warped the head and worst case a hole between the cylinder wall and water jacket(this is pretty rare).The only way to tell short of using some expensive tools or taking to your local shop is to pull the head and inspect the gasket for leakage wich is generally fairly obvious(separation of the gasket layers,oil and water between water and oil passages)and checking the head deck for warpage.If there is obvious leakage in the gasket you're looking at a top end gasket set if the head is slightly warped you can get away with a thick graphite head gasket,I personally use these as they are very forgiving on slightly warped and scratched head decks and inepensive also,but a severly warped head will require milling at a machine shop or replacement.

I hate to tell you but most likely your head gasket is blown. But first have your 13 psi cap pressure tested. If the head gasket has blown out in between the cylinder and the water passage , engine compression will enter your coolant and over pressurize the cooling system. This could be caused by a pin hole in the head gasket and that is all. also make sure your head is not warped. The 22re has a cast iron block and aluminum head causing the head to expand at a different rate than the block. causing the gasket to wear and leak. Good luck.
