It definitely would be nice to know the exact shape the motor is in but I would rather not pull it all apart because of how much of a pain that is. I can tell you I definitely take care of it (at least since i have had it). I don't really have lifter tick at all. No noticeable knocks. Gas mileage is consistently 22 mpg. When I changed the plugs and wires around 100,000 there was not excessive scorching or oil buildup. Even though i use full synthetic I don't go past 4000 miles without a change. People may gripe that I'm wasting money but whatever. I know it's good clean oil in her all the time. I watch the levels too since she does eat some oil with the infamous DOD/AFM.
I just can't get around what would cause that body odor smell in the used oil. I have always used synthetic, but that odor, at least from what I can remember has been with the last 2-3 changes. I did not notice it the year prior.
I'm thinking I will send in a sample of the oil. Maybe use some seafoam in the oil, for a very short duration as well. Every once in a while I will use it in the gas tank.
In the next month here I will be sending in my computer to Overkill for a tune. Get rid of that DOD/AFM plus the tranny benefits that will follow with their tune.
