I just decided to do a compression test and I saw that all cylinders were about 150 except number 5 , it was about 75psi. I dropped oil there and it went up. BUT before I call it the rings let me also say that its smoking whitidh blue quite a bit through exhaust but there is no mixing of oil and coolant in the engine or radiator?? There is oil coming from the back of the motor around the cylinder 5&6 area. I can't tell if its coming from directly between head and block but it does kinda looks like it. Could it still be a bad hg? Could putting oil in cylinder and making the compression go up be a sign of a bad hg? Or is that only for rings?
