No you do not want to paint the inside surfaces of anything like timing covers or valve covers.. a little mist of overspray here and there wont hurt nothing but not any more than you can avoid..

nothing inside. inside bad, no good, wrong, not right, evil, unhealthy !!!

I see engine builders painting the lifter valley. What's up with that?

They are using a paint designed for helping the oil to drain faster to the oil pan.

I always paint the valley and timing chain area with Glptal to promote drainback.

masking tape and a razor is your friend!

Also, the DUPLI-COLOR rattle can engine paint works really well. I painted mine over two years ago (orange) and it still looks great. Take the time to prep it good, you'll be happy with the results if you do..

That's the most important step for sure. I failed to do this on an engine I built...wow, coming up on 12 years ago I guess...and the paint peeled within a year. It's in my pickup, so I just haven't made time to pull and detail it
