The benefit considering the necessary effort, and potential mess is questionable.
This thread is timely, today I changed the
oil and filter. With the way my filter is mounted on the frame rail (low) a fair amount of the
oil trapped in the lines drains when the filter is removed. I had a fitting at the cooler that was very difficult to get sealed when the car was being assembled ( it seeped for some time) and to consider removing the fitting to drain the cooler is not something I want to do. After changing the
oil and before starting I always install a "Dummy" distributor and insert a shaft to spin the oil pump for a couple of minutes to refill all the lines, eliminating the air in the lines and refill all the galleys.
