I think I ask Dave to check some things on the engine and get back with me. When it comes to engines and customers there is not anything that is normal or we would never have any problems. Without inspecting the engine myself I have no way to know what may be going on.
It sounds lke this is the second owner of the car and I do not know the history of the engine or how it was treated before Dave purchased the car. There is something cauing it to use that much
oil and it might be a easy fix. I would have to have the car or the engine to help with the problem.
When you do as many engines as we do you see a lot of unusual stuff. Check the things that I suggested and get back with me in a private message or call me.
Thanks, Keith
