I have a 1999 Honda Accord LX. Motor oil is leaking into the cooling system. There is NO water in the motor oil. We have replaced the head gasket, water pump, timing belt, radiator, thermostat, head bolts, hoses, checked for leaks in the head, shaved 3/1000th off the bottom to level. IT STILL LEAKS oil into the radiator. My mechanic is stumped.
HELP!!!!!!!!!!!!!!!

 

Either cracked block or, if auto trans, cracked cooler in radiator. Possibly bad gasket or seal install. One can only speculate at this point.
