Another problem my 75 Imperial has is that there is a severe exhaust leak
from the drivers side. I thought it was the "doughnut" gasket but feeling around
the joint with my hand while the engine is running from underneath I feel no air
escaping so I don't think it's that...someone told me that these manifolds have
a tendency to crack and that almost certainly that will be my problem once I
take it off and see.......Is this true, that these manifolds like to crack on
the inside?...If so I would like to get one ahead of time so as not to be
waiting for it in the spring when I redo the exhaust to dual and deal with this
leak....I tried to spot a part number on it but I don't really see any exept a
very blury unreadable one towards the front of the manifold which looks more
like some kind of casting code rather than a part number....Does anyone know
what the part number would be for this drivers side manifold and where to
get one other than ebay..also from what years and models of cars did they use
this same manifold?..thanks for any help in advance!
