No, no damage to the O2 or cat.
I have worked in several garages that used the ATF treatment for city
driven cars as part of a full tune up. No damage was ever reported.
They even sell a product in a spray can for this and it smokes like ATF.

I have worked in several garages that used the ATF treatment for city
driven cars as part of a full tune up. No damage was ever reported.
They even sell a product in a spray can for this and it smokes like ATF.

My understanding ,,, water creates steam ,,, which may remove the oil from
parts like valvestems, rings and so on ,,, which is not good. If it was me
and I had a carbon problem, I'd first figure out what was causing it, then
fix it (not that I haven't had a few old beaters that carboned up
regularly).
And if I had 150 out of 140 ,,, I'd consider myself a lucky guy and go buy a
coupla lottery tickets :-)

That means you engine is good and strong. I wouldn't worry about the 150
number, I would worry about large variances among them. The tester he used
could be out of calibration enought to read a few psi higher than it should.
The relative difference among adjacent cylinders is more important than the
actual numbers you get.
