Re: Depression and thermostats
No, itís a Volvo MD7A raw water cooled engine, salt water circulates through the exhaust Mansfield around the exhaust chambers. The water comes from the pump, into the exhaust manifold, then to the head/block, back to the exhaust manifold, then the thermostat housing, and only then to the exhaust mixer.
My observation (hope?) is the the vast predominance of the buildup was in the pipe to the exhaust manifold and the manifold but the head and block seemed to be relatively clear. Not sure that is in fact true, just the way it looked from my limited ability to see.
