I have a C3 but thought this belonged in the C4 section since the engine is from an 87. When I bought the car it already had the TPI motor in it. Recently I had to take it apart down to the heads due to corrosion. So since I had it apart I thought it was a good time to paint it all and make a cover since I never had one before.
I have a 3d printer handy and thought this was a perfect task for it. So after a day of measuring, modeling, and test fitting, this is my final result for a cover. This is as it was printed, I plan on painting it with the same paint I used for the rest of the parts. This is printed in black abs plastic.
Catch ya later,
