losing coolant from no apparent hose or fitting Overheating You might be able to see the crack and sometimes the cracks arent visable by our eye. your over flow container will be bubbling even when you first shut the veichle off. you will notice thick white smoke pouring out your tail pipe. this is caused by either a cracked head, cracked block, blown head gasket and or a cracked intake plenum. if you take the head/s off of the engine block check very closely for cracks on the head and examine the gaskets for missing peices of cracks, to the same inside the cylinder walls. if you canot see cracks on the head/s take it to you nearest machine shop and they wil inspect them for you. if you do not see cracks in the cylinder walls you have a couple of options, A: turn the crank shaft manually so the pistons will move so you can see the rest of the cylinder walls B: drop the oil pan and remove the pistons from the crank shaft so the entire cylinder wall will be exposed, but BE CAREFULL!!! If you must remove the distrubutor for any reason make sure you mark where the harmonic balance was or you will mess up your timming. C: take the block into a machine shop and have them "magnafuxed" the block, this will tell them exactly where the crack is. Good luck!
While it maybe possible to find a macihne/welding shop to repair the crack, it most likely will not last very long due to the stress and vibration the block goes through while the engine is running.
Your best bet is to buy a new one. At that point you have two choices. 1. just replacing the block would probably be cheaper as far as parts, but you'll build up an expensive labor tab, not to mention all the new seals/gaskets and fixing the parts that cause the block to overheat and crack in the first place. 2. your best option is to have the entire engine replaced. you can usually pick up a crate engine (already assembled and ready for install) for a couple thousand, plus the labor of installing, which a good mechanic could probably do in about 6-8 hours depending on the car.
A cracked engine block can cause different symptoms depending on where the crack is. The coolant could leak into the water or a cylinder. The crack could cause low compression in a cylinder. The crack could also leak coolant into the oil.
What is the year of the Avalon? I have a 2005 Corolla (with only 72,000 miles) that just got diagnosed with a crack engine block.
It would depend on where and why it cracked.
Use a magnet. If it sticks to the block, it's cast iron. If it won't stick, the block is cast aluminum.
call a machanic
Antifreeze in the oil of any engine means there is a crack in the head gasket, or worse, in the block.
it is not a cracked engine block it is just a loose block
Yes.If you have no antifreeze in the radiator or engine,sometimes it will freeze.Usually a freeze plug in the engine will pop out before any major damage is done. Sometimes the block will crack,or the radiator will crack or burst if no anti freeze is in the system.
The repair is most likely more money than the car is worth, you need a new engine block.
Usually this is due to the engine having frozen, normally due to insufficient or lack of Antifreeze. Or the failure of Block Heaters. Water expands when it freezes, metal contracts as it gets colder, consequently, the cooling system will burst at it's weakest point.
Lack of anti-freeze in sub-freezing temperatures. The water in the block freezes and expands.

Yes
Are you talking about a crack in the engine block? Sorry, it's not repairable.
yes
It should not
no

If ice forms anywhere in the engine, it can crack the block.
Most definitely.
crack the engine block and oil mixes with water or antifreeze.
Antifreeze helps by not allowing the coolant to freeze and possibly crack the water passages of the block.
