ok i know this is something i shouldent need to ask becouse i should have never let it getso hot but i need to know how to tell if the block is cracked i found out that my fan was bad so i just got a new one and need to know how to tell any info on how to tell thank you all alot

 

coolant in the oil.
White smoke from the exhaust
Overflowing reservoir bottle.
Coolant in the plug holes.

 

Strictly speaking, we don't have blocks, but a modular engine, sometimes refered to as a keg. What makes you think your's is cracked? Overheating usually blows coolant seals, warps housings.

 

ok thanks for that info didnt know what to call it and i was told that overheating cars will crack the block and that would mean that it would happen to a rx7 easier becouse its mostly alluminum and i was told that if you have like white **** in your ratiator thats bad and there is this black gunk on the cap so ya any info would help and about the warp housing wouldent that still be very bad and coolant seals that would mean i would have to rebuild the motor right?

 

o and if i did blow the coolant seals or warps housing what would driveing it do plz i need some info thanks

 

Hey, what exactly are your symptoms? Or are you just trying to borrow trouble?

 

im just wanting to make 100% sure that i dident brake something cuz i over heated it bad

 

Well, at this point, as long as you are not still overheating it, I would run it and see if any problems raise their ugly head.
But, best case scenario, I think you just significantly shortened the life of the engine.
