The original head on the '87 190D suffers the same weakness as the original #14 head on the '87 300D. My '87 190D required a new head (although ironically I've never had a head problem with 4 #14 300D heads, ... yet).

Hopefully it is a gasket, but be prepared and check for a crack when you disassemble if the car has the original head (casting numbers are listed in the FSM).
