Surprise.. its leaking coolant between head gasket. Look like those stupid threaded core or cast plug's at head surface is leaking. Only one. So have to take head off or add some coolant sement/sealant. Its small leak, but big eneught to make small pee to my garage floor..

I just don't get it. Why?

Also some guy here in Finland bought 4.8l stroker torque engine in same place as my heads. Engine last approx 2000km and totally destroy bottom end.. Crank or rod bearing blows and destroy block and crank. And no warranty..

She's running. I add Bars Leak original to cooling system and 2x running cycle cold to hot will eliminate leak. It will leak approx no more than 1ml of coolant only when hits operating temperature ~82c. And allways stop after that.
Now i flush the system and start again without leak. I hope there is enought stuff to make it seal. I do not flush heater matrix or block. Only radiator. Will see.
Waiting for summer to get it back to road and dyno..
Then cry if blow up or less horses than std heads.
