Hello. I'm going to rebuild my B21F engine and I have a couple of questions. I would like to use synthetic oil in my engine for its life-span; but I'm unsure about a couple of issues with its use. Here are my questions:

0. If I use synthetic oi, how do I do the break-in? Do I do a break-in at all? What procedure should I follow?
Example: a- synthetic oil and new filter
b- break-in procedure
c- change the oil and filter
d- etc???

1. I want to paint my engine but I see one big issue: I've never rebuilt an engine before. Because of this, I think that:
a- I should rebuild the engine
b- break-in the engine
c- check for oil leaks, etc.
d- re-torque all important bolts (head, intake, etc.)
e- remove the engine and THEN paint it
f- reinstall the engine

I have no problem with installing the engine and then removing it again. I would like to know what you people suggest to me. Thank you for your time and for the advice; it truly helps.
