Question about 2003 Mazda 323
The car starting with engine gauge temperature rising and cutting off air conditioner but not going in red. However 2 days later it went into overheating and water started to boil in overflow bottle. So the mechanic it as digonized it as head gasket leak and rebuild the engine. However on putting it back together it wont crack and does show any fault (777). Anyone got any idea what it could be there are recommending to replace crank sensor.

I have a 2004 that had the same problem. It sounds like the engine might be flooded. The best thing to do is to remove the fuse to the fuel pump. It will be listed under the fuse cover under the hood. Mine was a 20 amp but check to be sure. With the fuse removed, crank the engine for a minute to remove any fuel flooding the engine. Replace the fuse and crank the engine in 10 second intervals without touching the gas or you will reflood the engine. This process can sometimes take awhile and will drain your battery, so have it connected to an additional power source ( i.e. another car battery or jump box). When the car finally cranks over there will be a huge cloud of smoke so don't be alarmed when it happens. Lastly some words to the wise. This process CAN ruin your starter, but is essentially the same process that the dealership will you except that they will remove the spark plugs to drain the fuel and then charge you for new ones. If this process doesn't work then you probably need new spark plugs which is going to cost quite a bit. I was quoted upwards of $525 to fix this problem until I talked to a Mazda mechanic and found out how to do this myself. Just make sure that the engine is up to running temperature before turning the car off and you shouldn't encounter this problem again. I hope this helps you, and remember that if all else fails the dealer can fix it. It won't be cheap, but they will get it done.
I almost forgot, you HAVE to get the oil changed as soon as possible because there is probably gas in the oil now.

i had a similar problem with my 626,what sorted it for me was to clean the crankcase breather tube on top of the rocker cover.The little valve inside this seems to stick but spraying some air intake cleaner (comes in an aerosol can) frees it out and allows the engine to breath better and so tick over evenly.

SOURCE: engine overheating
All i can think of is the thermostat is not opening. or you may have a clog somewhere preventing the flow. Check the T-stat and hoses and radiator ( for clogs) Good luck
