I know what the book says about run in procedures, but curious as to what
others may have done in the real world.
I rebuilt my first TR ( '65 TR4) in 1971 and my neighbor ( an engineer
motor head type who taught me a lot ) said the way to break it in was the
way he did his Griffith, namely, by counting shifts. If I recall
correctly, it went something like go up to 1500 for the first 100 shifts,
then up to 2000 for the next 100 shifts, and so on. I remember how proud
I was that I kept up with the number of shifts and believe it or not, I
stuck with the routine. That car ran great until I sold it.
I did it with the 250 rebuild back in the early 80's. The bottom end
stayed together but the valves sank into the head.
Any others care to share their stories?
