Wow Les, at least you are running new parts. I just get used stuff. I got a doner valve in my aorta and they could not find anyone running down the hall at the hospital to get a vein from so they took one out of my own leg to fix one in my heart. That was 2 years ago in March and I am doing great with no blood thinners other than an aspirin a day. The mechanic, er surgeon, that did the valve job said I should be good for another 100,000 miles if I don't run wide open all the time. Fat chance of that. Compared to what I use to do I just kind of run around just above idle now.
