Are you loosing coolant?
Is coolant getting mixed with oil or vice versa?
Run engine to normal opeating temperature
Remove dipstick and let a drop fall onto a hot engine part
Oil will smoke coolant will sizzle Do a compression test
2 adjacient cylinders with low readings indicate a leaking head gasket
