Once freed I am sure it would clean out since unlike the last owner I plan to do frequent oil changes in this car. When I bought it the engine oil was very black and about 2.5 quarts low. The poor car only has 75,000 miles. Of course I know that if I spray anything foreign into the lifters I would need to flush the area with fresh oil then drain and change all my oil, maybe even twice after running the car for a few minutes on the new oil.
I would use Liquid Moly oil sludge flush. There are really positive reviews on that stuff.
