On the thread about the skid steer headed towards a 4BT transplant. I just came across a customer today with a S4S that is over 18,000 hours. We would like to rebuild it soon on general principles. In the pictures that come up in the search it looks like the engine has something like top stop liners but in some video I found it looks like somebody is chipping out dry liners but the service manual I have it looks like parent bore. So which is it and are there any other interesting features inside this engine?
