sleeves
Since I now know that I have an early model, which makes it at least 30 years old, I am concerned about the water jacket. When does one re-sleeve? Are there sleeves in the first place? (my '58 TR3 had them). Any other areas of concern in this regard that are potentially devastating from the point of repairability?

Doug,
While sleeving is sometimes a very good option during a rebuild, it's not necessarily the case that an engine needs to be sleeved simply as a function of years in service. There are at least two situations where installing a sleeve (or sleeves) makes especially good sense:
With respect to the condition of the rest of your block, one of the best places to check for corrosion is to note the number of threads remaining in the manifold stud holes. Three threads are considered minimum before installing a threaded bushing or other equivalent thread replacement, but even in this case, we would not necessarily install sleeves. Be sure to check the upper circumference of these holes, because the upper part tends to corrode somewhat faster than the lower part. As a point of reference, the newest block we ever saw had 6 threads in the location of the manifold stud holes. Best regards, Don Moyer |
