what could keep the oil in my sump(to burn)
rather than circulating to the oil tank and cooling
lines.
i saw this once when someone over filled the tank.
my tank does not register over the dipstick marks.
the oil acctually billows grey smoke enough to
make the neighborhood unbreathable.
my first move will be to drain all oil and replace all
filters and gaskets.this motor worked fine until i
transplaneted it 2 years to the current car.(any ideas?)

Hi there,

If you are burning oil, i would be doing a wet & dry comp test first to get a better idea as to the condition of the rings first.
