There seem to be issues lately concerning
oil burning and Ford Z-heads. See this thread:
427 burning oil-another one
As I have two engines running Z-heads with less than 500 miles on each, but no problems to date, I have a few concerns. If you have them on an engine, please answer the following questions:
1. How many miles have you run with them?
2. Have you had any problems with
oil consumption, smoking, etc.?
