hi i have a 1999 cl 2.3 vtec auto with oil mixing with my antifreeze, with no milkshake on dip stick but radiator is full of the stuff. thought it might've been blown tranny cooler but tranny fluid level is good, took off head sent it out for a M.R.I was told head was worked on before but fine. I'm hoping my block is not the problem. SOS

 

Block I bet it is.
Been there.
Sometimes oil in rad ... sometimes coolant in crankcase.

 

it's your head gasket
