[DML] Re: PRV Oil Passage Problems

["content22207" <brobertson@xxxxxxxxxxxx>]

B27 and B28 camshafts are constructed from the same material (only
difference is cam height). Both engines share the same small oil
passage problem to the valve train. Both suffer from excessive wear if
oil is not meticulously maintained. The problem was not resolved until
B280.

F series merely denotes low compression North American import. There
are both B27F's (1976-1979) and B28F's (1980-1987). The engine I
purchased last fall is a B27F.
