They are pulling the heads on Friday.

once manifolds are pulled off - it will be apparent if the manifolds/risers caused the problem.
if indeed the manifold/risers caused this condition - the motor was taking in sea water.water in the oil,it may or may not have been present,but,the motor was "burning" seawater,due to valve overlap ...
with all that:
a common problem often encountered,after having the cylinder heads rebuilt - a "valve job"
the motor will have an oil consumption problem.blow by,on the rings will cause this.the seawater in the cylinders causes wear on the rings - just inspecting the cylinders,will not pick this up...if water was in the oil,this causes a problem with the cam bearings,causing a low oil pressure situation ....
lots of "stuff" to all this huh ??
