[DML] Re: PRV EGR

["content22207" <brobertson@xxxxxxxxxxxx>]

K Jetronic PRV's were designed for honest to goodness EGR through the
U pipes (that's what the port under that plate is for). Volvo used it
on North American imports -- look closely at the B27F pic in #5939's
photo album. DeLorean of course did not. Did not use a smog pump
either as Volvo did.

Bruce is right about the hot air pipe: does not route anything from
inside the engine. Simply allows outside air to be drawn over the
exhaust manifold to heat it up.
