1 million mile goal, no more

Was trying to hit the 1 Million mile record but not going to make it anymore on the original engine! Burnt a valve at 680k but still had 70-90psi compression cylinder 3. But this time #2 cylinder no compression. Plug was oil fouled, start smoking at warm up in the morning about 6 months ago. That might of been a sign. Plan to drop in the spare CVT motor in it
