drain about a quart of oil out, and replace it with some marvel mystery oil. that stuff does wonders for high milage motors. I threw a quart of that stuff in a junkyard AMC 360 v8 out of a cherokee with unknown milage (at least 100k judging by the stretched timing chain), replaced the filter and drove around for a week, then changed the oil + filter. engine really quieted down.
