My 20 year old 200k car (ok 24yr/256k) is definitely not dry. But it’s not from the PS nor ATF lines. I think the front main seal and valve cover gasket, although as a 5S-FE it might just be every engine sealing surface, as I think it just likes to leave its mark in this world (done the VC a couple of times, but it’s determined to not behave).
