Hrm...
After 1,000 miles and 20 cold starts, decided today to do a check. Idiot me, I should have checked with my fingers--instead, I just put a wrench on it. Loose! !!!! Not majorly loose, but where I failed to give a finger check I can't say it wasn't. Am going to have to check again, maybe I have a problem here...
Before anyone asks, I've done the last twenty-some-odd changes on this car, new crush washer each time (OEM one at that), and never noticed anything stripped or otherwise off. Nobody but me has touched this bolt in the last 6 years. I've never used a torque wrench on it, because, well, you don't need to, just give it a good snug and it's done.
Wild.
[In other news I think the o-ring on the oil pump for this 5S-FE must be on its way out, something is starting really pour the oil out--and yes, I did change that 6 years ago, but not the crank seal, but the leak looks more to the rear than on the pan. Could be either or both. Need to wait until warmer weather and when I can take a week off to do the TB. *sigh*]
