|From the left are the heat exchanger, exhaust manifold,|
the mixing elbow is perched on the manifold
and the cylinder head with intake ports
I gave the exhaust manifold and mixing elbow to Kenny to pressure test. He suspects the leak may be at the metal gasket mounted between the elbow and manifold. This gasket blocks water ports in the manifold that provide cooling water to the turbo on the turbocharged version of our engine. Kenny's pretty busy right now, so I may not hear from him for several days.
|The turbo charged version of our engine has the turbo|
mounted on the manifold. Cooling water for the turbo comes
from the water jacket of the manifold
|Our engine has the mixing elbow mounted on the|
manifold. The water ports in the manifold are
blocked by the gasket (#16) that is inserted
between the elbow and manifold.
By the way, the cost of a used manifold: $1500. Ouch!
