Bob,
I have heard a number of stories from people about how they noticed their
oil pressure dropping and when they checked their
oil, found it was down a couple of quarts...
When they added
oil, the pressure went back up.
This puzzled me. I wouldn't have thought that could be possible (unless they were down MORE than a couple of quarts - I guess)
Perhaps a restrictor in the head is missing in these cases as too much oil is ending up in the valve train area.
Just a thought.
