Restoring Corvette Intake Manifold
Restoring a 1972 Corvette intake manifold to its former glory requires careful attention to detail and the right techniques. In this video, we’ll take you through the process of using electrolysis to clean the manifold and engine enamel to paint it, giving it a like-new finish.
The process begins with the removal of the intake manifold from the engine, taking care to disconnect all hoses, brackets, and electrical connectors. Once removed, the manifold is submerged in an electrolysis tank, where an electric current is used to break down and remove years of grime and corrosion. This gentle yet effective method ensures that the manifold’s surfaces are not damaged.
After electrolysis, the manifold is thoroughly cleaned and prepared for painting. A high-quality engine enamel is applied, carefully matching the original Chevrolet orange hue. The paint is applied in thin, even coats, allowing each layer to dry before applying the next. This ensures a smooth, durable finish that will withstand the heat and rigors of the engine compartment.

For electrolysis using washing soda, several references provide guidance of using 1 tablespoon of washing soda per gallon of water for electrolysis projects. It is important to dry and treat the metal immediately after the process.

The OSPHO Technical Bulletin from Skybryte Company provides information on their product, OSPHO, which has been produced for over 50 years to help treat and prevent rust. According to the bulletin, once OSPHO has dried, typically overnight, it is totally neutralized and there is no longer any acid on the surface that could react with paint. However, a small amount of powdery-like material may remain, which should be blown, brushed, or rinsed off before painting. It’s also important to allow adequate drying time before painting, as water from the OSPHO solution can hide in nooks and crannies, potentially causing adhesion failure of the primer. Additionally, a quick water rinse after drying can remove any trace of reaction particles and ensure the surface is in perfect condition for priming.

Dupli-Color Engine Enamel
To paint with Dupli-Color Engine Enamel, follow these steps:
• Surface Preparation: Remove dirt, wax, and grease using a quality grease and wax remover, then scuff sand the surface with a scuff pad for maximum adhesion.
• Application: Hold the can parallel and 8-10 inches from the surface to be painted, and use in an even, sweeping motion. Apply 2 light coats followed by one medium wet coat, allowing 10 minutes between coats.
• Drying Time: The paint dries to the touch in 1 hour and can be handled in 3 hours.
• Clearcoat Application: For additional protection, apply Dupli-Color Engine Enamel Clearcoat within one hour of completing the color coats, following the application instructions on the can.

What is the electrical wire you unplug from the front of carburetor ? Minutes 3 on video ?. Love the video
@mickaelblais8700 Thank you for the question, Mick. It energizes the idle solenoid on a Quadrajet carburetor, which functions primarily as an anti-dieseling device. It becomes energized as soon as the ignition is turned on and remains so until the ignition is turned off. Its purpose is to reduce or eliminate engine run-on or "dieseling" after the ignition is turned off.

Thanks Mike .
I have a 72 carb on my 73 and I never knew what it was. Mine is not hookup to anything . That why I got some back fire sometime ?
@mickaelblais8700 that's possible, but I'm not a carb expert. When they work, I'm happy.
I appreciated your earlier positive comment on the video. Thanks for that.
@mickaelblais8700 I bet a quick question using AI would get you a reasonable answer.
Well, what do you know. Here's the answer from my favorite browser's AI
"A Quadrajet carburetor solenoid, also known as an anti-backfire solenoid, is designed to prevent backfires by shutting off the fuel supply to the main jet when the engine is turned off. If the solenoid is not functioning correctly, it could indeed lead to a backfire when the engine is shut down. "
