After discussing Ajay Sharma's difficulties recently, I'd say don't
bother.  I've read a number of times of people spinning bearings right
after using engine flush.

Here's my monkey-assed guess what is going on.....

The engine is full of tiny oil passages that we normally don't
notice.  They exist in the crank, block, and rods to say the least.  Some
of them are less than 1mm in diameter.  I think some of the problems people
have had are due to the flush dislodging gunk without fully dissolving it
and it ends up clogging one of these passages.  A little oil starvation on
bearing and you're hosed.

So, now you have my guess.  Please shoot any holes you like in this.  It's
just a guess.
