There is definitly a leak that I can hear just turning the engine by hand. I plan to pull the head as soon as my parents don't need my constant attention. Thanks for the picture. The oil passage to the head is what I have wondered about. The oil and the coolant don't seem to be mixing either way as far as I can tell so far, but some coolant may be disappearing. My brother in law, a long distance truck driver, had just bought the car a week before he dropped it off to me to check and straighten up a few things. When he bought the car from my neighbor, I drove it about 15 miles to his home and temp stayed about 190°. But when he drove it back, he said the temp would get about 210° before dropping back. I replaced a bad radiator cap and added exactly 1 gallon of coolant to put it close to full. The coolant recovery tank had 2 quarts of coolant in it.
