Anybody familiar with the Magnum motor?

Posted by P Backus on December 01, 2005 at 21:08:40 from (69.128.32.197):

7140 Magnum with the Cummins 6TA 830. Some of you may
remember last spring I was asking about coolant getting into the
engine oil. Did all the tests, had the pan off, pressured it up, no
leak. So I ran it this summer with just water in the cooling
system,so as not to destroy the bearings, hoping the problem
would become obvious. Nope, just kept putting the water in the
oil.
Anyway, my question is, is there anywhere in the timing gear
area where the coolant can mix with the oil, like a frost plug or
something. If you take the timing gear housing off, is there an
opening to the water jacket covered by a gasket perhaps?
The last couple of days of my fall work, it suddenly stopped
losing coolant, but started leaking LOTS of motor oil out around
the timing gear housing area. So what the heck- this doesn"t
make sense.
Just wondered if any of you remember what"s between the block
and that housing.
Thanks,
Paul
