The second cleaning cycle is finished and I am now ~5000 miles into the treatment.
The link to the site is here.
Be aware that I have changed the gallery so any old links to photos will no longer work.
Rugerman has understandably asked me to post as much of the information as possible here so that it wouldn't be necessary to leave BITOG to get an update on this test. With respect to his wishes here are the latest "Stats" and my "update" along with what is arguably the most dramatic comparision image:
8/14/04-126,804: The second cleaning cycle is complete and the latest photos are up. During this cycle I noticed that the oil got really dark for the first time. I also see that there is a considerable improvement in compression and interestingly, the spread between one of the cylinders is a bit higher than before. Without opening the engine for a look I can only assume that whatever crud was causing the rings to stick is definitely coming loose now. Except for cylinder #3 the engine is actually within it's specified compression range. As for #3 I am optimistic that it will improve during the upcoming final rinse cycle. The engine also does feel a bit stronger now.
