Got a 17 focus ecoboost 1.5l in atm found miss fire and lose of coolant found leak internal cylinder 3.

Got used motor from wreckers apparently 10k on the motor, found plugs to be oil coated and carried our comp test 190 in cylinder 1,2 and 4 Cylinder 3 50 PSI put oil in it tried again cranking longer (bench test not in car) came to 80PSI. I reckon we send it back and get another but the manager want to entertain the idea its a 10k motor and it will come good after start

Carried out

Comp test wet and dry

Borescoped the cylinders before comp test quite oily and carbonated

Will be carrying out leak down tomorrow

What do you guys think
