OK, here is part two of my engine rebuild story. You can read part 1 here. I went up to Chilliwack yesterday (June 23) to check on status, since the head has just returned from the machine shop. A couple of weeks ago we decided to bite the bullet/wallet and completely rebuild the head. It was just so fundamentally botched that it was beyond the point of getting it right without a total rebuild.
Like every other layer that we peeled back so far, more horrors were revealed as the head was disassembled. Valves cut. Under-spec shims & tappets. Improper washers. Valve seats almost gone. The bottom was not machined flat, but had a .002" concave furrow running longitudinally down the middle. NOT what you would expect for an engine rebuilt less than 10,000 miles ago by a supposedly world-renown shop. If you are considering having Classic Jaguar of Austin, Texas work on your E-type, or any car for that matter, have a close look at their work here.
All the bad bits have been yanked out and thrown in a box. The bottom ground perfectly flat - along every axis. YES Ray, as little metal removed as possible to get it flat again; and we *will* compression test once back together!
