Mk3 overheating please help
 

HELP, I have a 87 supra turbo and it overheats really quickly. Im new to the car and i have looked through the forums and figured it probable is a BHG but im still not sure of the problem cause it matches some of the symptoms but i just wanna clarify. I cant get it checked by a mechanic because the car cant even make it out of my neighboorrhood without the temperature guage hitting max loool. When the car starts to overheat, the radiator cap starts fuming water vapor or something? and theres a little bit of coolant residue as well.

BHG symptoms is large amount of white smoke from the exhaust and fumming from where you put the coolant, but theres little white smoke, and its probably cause it was cold (canada lool) and the coolant wasnt boiling from the bottle u put coolant in the car.:confused:

The engine oil cap has a little bit of white crust on the lid if that helps and it looks kinda milky? so hopefully the description helps and ill put a picture of the engine and the yellow circles where the smoking from the radiator cap is and i have pictures of the engine oil too. :help:

PLEASE SHARE YOUR SUPRA WISDOM AND KNOWLEDGE WITH ME

Based on how that oil looks you probably have a bhg. Drain the oil to confirm, it'll likely look like a chocolate milkshake

The pictures confirm water in the oil. The most likely cause is a head gasket failure.
I would strongly discourage runing the engine.
Ethylene glycol is damn hard on bearing surfaces and can cause further damage to your engine. The rapid over heating you describe is bad news for your engine as well.
I fear a complete rebuild is in your future.
