Never called his expertise into question -- I agree with him (not that my
agreement in any way confers some kind of validation of his expert status.)

Given time in contact with oil, it seems that _some_ gaskets will swell
back to their original thickness. This is just what I've heard (I'll try
to dig up the source).
My point was that all of the goop left behind by dino-juice can hide
deteriorating gaskets to a degree because it clogs up the leaks, and that
when the goop is cleaned away by the synth, the problem is uncovered.
To my mind, this is a good thing. Keep in mind though that I'm one of
those psychos who clean their engine regularly so that I can catch any
leaks easily and prior to a big malfunction.

Don't take what I said personally. I was just pointing out that, while you
certainly wouldn't neglect your brakes (or other bits that keep you alive),
there are other maintenance issues that seem to get neglected by a lot of
people -- in spite of their long term impact (CV joint boots fall into this
BTW, to avoid another synth-oil thread, and as punishment for even touching
the subject, I am now going to read every synth-oil related post in the
archive and will not re-surface until I am done. See you all in December.
