The only way to know for sure, is to remove the head and have it magnafluxed. If it has either of the above in the question, the head would have to be removed anyway.
A cracked block means that the engine itself is cracked. A blown head-gasket means that the gasket between the engine and the head has blown. Either can be caused by overheating the engine. When an engine overheats the head can warp causing the head-gasket to give out. In some engines the heat cracks the block. If the block is cracked, it's over. If the head-gasket is blown you can always machine the head surface and put it all back together.
If you suspect the head and/or the block, have them "magnafuxed" by a machine shop. On the other hand, as you're pulling it apart, check the head gasket and if it's shot, there is usually only the one problem.
The difference between the two is that an asbestos gasket uses asbestos as a reinforcing fiber while a non-asbestos gasket does not.
A blown gasket can be repaired by replacing the gasket...if you are talking about the head gasket, then you have to remove the cylinder head from the engine block and replace the gasket that is inbetween them. Cracked heads generally have to be replaced because they are made of aluminum which cannot be repaired permanently once it is cracked.
blown head gasket or cracked block blown head gasket or cracked block
Blown head gasket, cracked head or cracked block. Busted head gasket; cracked cylinder head; broken piston; or bad oil pan gasket if driving thru high water.
Engine will possibly overheat, coolant will mix with the oil, and eventually destroy the engine. You must replace a cracked head gasket.
Have a compression test run to see if you have a problem with the head or gasket. Once you find out you do, then you must remove the heads in order to determine what the problem is. Have the heads inspected at a machine shop to determine if they are warped or cracked. Once the heads are removed the gasket must be replaced so it really makes no difference.
Could be head gasket, head, or cracked block
To tell if the head is cracked, you have to remove it from the car, so you will replace the head gasket, anyway. Take the head to a machine shop and have it magnafluxed to see if it's cracked.
Yes. The head gasket forms the seal between the engine block and the head(s). The valve cover gasket seals the gap between the valve cover and the valve train it is covering.
Let's see...cracked head, cracked head gasket, cracked intake gasket, bad cylinder liner or cracked block, air compressor head gasket...if this was a Cat 3116 I'd also look at the oil cooler or an injector sleeve, but it's not so that's probably not it.
