Exhaust manifolds

[cywagoneer]

I was wondering if I should try and paint my exhaust manifolds while the engine is out. They seem to be pretty rusty though I'm sure it is only the normal surface rust. Should I even bother trying to clean them up?

Also, I was surprised at how easily the manifolds unbolted from the heads, I figured they would be torqued down tighter than they were. Luckily I haven't had even the slightest leak in that area.

Peace be with you.

If you want them pretty for just a little while. The paint will not last long on exhaust manifolds. They will probably look even worse once the paint starts to fade. :eek:

What about the high temp paint for engines/headers?

I've had pretty good luck with wire brushing them, spray with engine cleaner, wash off, let dry in sun, then use hi-temp STOVE PAINT on them, lasts quite some time. Use a few coats.

I also use stove blacking paint on MC exhausts and it's good for a year and then it needs recoating more from scrathes and abrasion on a bike. It's easy to do though. It's NOT a rust proofing so the headers need to be clean metal before you put it on.
So far as your headers bolts being surprisingly loose...don't be surprised cause you'll be re-torquing them forever. Welcome to the world of tube headers smile.gif There are special bolts/lock available now that supposidly cure that prob but I've never used them. I've had my years of header hassles and avoid them like the plague now a days.
