Silicone RTV fumes can kill O2 sensors faster than you can blink. They
now make the more expensive 'sensor safe' silicone RTV. If you have
fresh silicone anywhere near the engine it could cause continuing
troubles.

I can't see how paint can get at sensors, but it could interfere with
some.

The only CPS's 'I' am familiar with just bolt in. There are no
spacers. I haven't seen that many though.
