I still have NOT checked the rear head oil returns. I may get to it today but I have my grandsons with me today and they want to go to the beach so I may not have time. I have been contemplating swapping the engine from my wrecked 1998 Olds 88 but am not sure if it'* compatible due to the redesign of motor mounts in the 2000-2005 cars.
Getting back to the problem with my Buick I had assumed that since the oil returns were clear on the front head that they were probably clear on the rear as well but now I'm thinking that whoever worked on it prior to me owning it may have just cleaned the front oil returns and gave up because of the extra work involved with doing the rear head!!!
