i got a 350lt1 rebuild new crank bearings rods at a machine shop and my mechanic barley installed it

well i finally turned on my car yesterday it was workng ****ng badass idle was dead on oil pressure was where it was sopos to be, temp was low everything was working fine , on my way home lke half way's to my house my motor all of asudden shuts down no crank nothing it woudent turn on when we pulled it back to the shop and drained the oil a bunch of antifreez came out wth the oil probaly its a head gasket

what could be the problem inside the motor right now it wount crank for nothing we put a rachet to the crank and we cant turn it for ****

 

If there is antifreeze in the combustion chambers it makes it impossible to turn it over. Thats how mine was when it blew the headgasket.

 

If there was antifreeze in the oil, it was running without lubrication and since it won't spin it sounds like you seized the engine.

 

what can i do to fix a seized motor ?

 

If it is indeed hydro-locked, remove the spark plugs to see if you can turn it over.

Sounds like you are going to have to pull the heads to replace the gasket.

 

Rebuild it again? Thats the only thing I can think of.

 

these are dead on for each scenario.

 

well they opend the motor and a piston was missing parts of the piston were everywhere but the heads are pefect no scraches

 

how about the cylinder walls? head gasket look damaged?

cause and effect are very important, what caused what to break and what was the effect

did the head gasket fail causing the motor to overheat and melt a piston, or did the piston break busting a water jacket somewhere
