Patrick,
This reminds me of a problem I had with my mother's Mercury Comet back
in the 60's. Water in the oil.
I pulled the heads and checked the gaskets and they were fine. While I
had them off, I took them to a machine shop to have them checked for
level. They were fine but the machinist said he could tell me without
looking what the problem was. And he did!
It seems that Ford in their infinite wisdom made the timing chain cover
out of pot metal. This is the piece where the water pump mounts and
becomes the place where all that pressure is forced upon. Guess what,
Erosion took place and washed a hole in the cover, pumping water
directly into the oil system. It seems that was a common problem on the
260 V8.
That may not be the case here but it is certainly worth checking out.
Regards,
Joe
