run a compression check on the motor sounds like it is leaking compression into the cooling system

how do i run a compression check?

get a compression tester most auto parts stores have them as a loaner tool. pull all spark plugs and go cylinder to cylinder spinning the motor over and record the readings there should not be more than a 10 % variance. somewhere around 160 psi. if you are not comfortable find a good shop.
