Powder Coating Valve covers
I am planning to send my top valve covers to Al Reed for powder coating. Do I need to drain the oil before removing the top valve covers?

Wouldn't be a bad idea.
Also, have them mask off the areas around the holes in the valve covers (where the studs go) A thick layer of powdercoating interferes with the sealing washers. AFJuvat

Oil does not exit when removing the top covers. However, if you do your own valve adjustments, it might be good idea to schedule the powder coating with this task as well as an oil change.

The powder coating will not allow the heat to escape as readly as raw Aluminum.Steve

Also
At least on a 930, the engine does get hot enough to soften the powdercoating - making it prone to scratching\marring. AFJuvat

Given that powder coating seems to diminish heat dissipation, I think I will forget about powder coating the valve covers.
Thanks for the warning. Guy Chiattello |

There will not be any effect on the heat loss from the valve covers. Even if there were, it would not be of any significance to the heat exchange from the engine.
Trust me, I'm a doctor. |

didn't the factory powdercoat the upper valve covers a golden sort of color on the 964's?

Oh, one other item -- you can collect old valve covers for very little $$, then powder coat them black, red and silver (or your choice) and rotate them at each oil change. This adds fabulous amounts of hp of course....
Some have used crinkle paint on theirs, and latho it's looks great when clean, I've always found crinkle paint a mess to keep clean. |

Powder coating is only good up to about 400 degrees. Not that these covers will ever see that kind of heat, but as the paint gets warmer, it gets softer as mentioned before.
Save your $$, buy a can of brake caliper paint and do the job yourself. Caliper paint is harder, withstand greater heat and chemical resistant as well. Can't beat a $5 can of caliper paint.

Al Reed did mine. He knows how to do the job properly - i.e. pluging holes, clean surface mating areas, etc. I have had no problem with mine and it really dresses up the motor. Easily cleaned with a damp rag too. Paint can not match the looks and protection of powdercoating. Drain the oil and send him the lower valve covers too, as well as the fan and fan housing.

Not to take work from Al, but. This is a becoming a very common coating/ painting method for hot rodders. You should be able to find someone local to you. Check around the hot rod/ speed shops to find your local artist. I did valve covers, fan and housing for $75 including the prep. The guy mostly did drag and show cars and was very interested in them "Porch" things.
