I agree mostly
But misfire on 2,4,&6 are all on the same bank.
So oil intake from the AOS should affect both banks equally.
But the OP just has the misfires on one bank.
I would look for something that would affect that 2,4,6 bank only.
First thing I would do is a very good visual inspection of all the wiring leading to that bank.
Something could have been disturbed by the previous work.
Some connection could be loose.
wiring could have gotten pinched.
Something could be grounding or shorting out.
Something I never see mentioned on this forum is.....
When one has a problem.
Before you even touch anything.
Get a flashlight and do a very intensive visual inspection
