Duke,
You have stated numersous times your philosphy that low mileage or
not properly maintained CV's will suffer from cylinder corrosion at
the top of the bores. I think you are making a blanket statement
that cannot be supported by FACTS. To date, Tima and I have taken a
number of engines removed from both running and nonrunning vehicles.
This condition is not usually the case. I am running a car that was
in storage for nine years and it has not blown a head gasket as yet.
I also have a cv that was in storage for eight years and due to my
own stupidity of dropping a foreign object in the cylinder, the head
had to be removed. However this one did have erosion around the bore
of one cylinder but still sealed properly.
You are both right and wrong in your statement. One will never know
what condition the bores are in until a tear down is performed. I
will agree that IT IS POSSIBLE for erosion to occur, but to make a
blanket statement that it will occur is doing everyone a dis-
service. As Tim Morgan and I can report, we have had no failures of
head gaskets on our low mileage cosworths.
As for the orange CV in TX. I do not recall all of the events around
the head gasket problem. But the car sit for over a year after the
gentleman passed away and started right up when pulled from the
garage. The only problem was a split fuel line at the rail
connection. The car runs great with no apparent problems. I suspect
that there is more to the story of the head gasket. When the head
gasket blew out, Randy had driven less than 100 miles since his time
of purchase. It is possible that a factory defect or an assembly
error occured, who knows. Only a teardown would reveal the condition
of the bores.
