Hi  can anyone give the cause to why my coolant is entering my engine and causing it to lock up

there appears to be no coolant mixing with the oil .

 

Hello Nick,

If coolant is entering the cylinders in sufficient quantities to cause this serious symptom, then you really don’t have to worry about whether the coolant is actually mixing with the oil. 

Point of ingress of coolant? Could be headgasket, or inlet manifold etc.so some degree of dismantling is obviously going to be necessary to locate the problem. 

I’m sure it goes without saying that any attempts to try to start the car could result in damaging conrods, pistons etc. 

Perhaps you could let us know how you get on from here.

Kind regards, 

Gareth.
