Re: backyard methods for internal cleaning an intake manifold? I just did a backyard cleaning on my RPM intake. It was fairly clean even after being on the car for ten years.
This is type designed for uncoated aluminum rims. It is pretty volatile stuff because it's made from four types of acid so be really careful spraying it and remove anything that you don't want ruined off the intake. Removing the manifold entirely is the only way to ensure you have eliminated all traces of carbon materials and other harmful contaminants that could damage your engine.
Aerosol sprays restrict the cleaning area, making the whole process much less effective than having your intake cleaned professionally. Regular, professional intake cleaning is not just healthy for your engine, it also offers a variety of benefits, such as improved performance, increased economy, and a better drive!
This important cleaning process removes dirt from the intake manifold, throttle valve, and carburetor on older parts of the vehicle. Carbon build-up can occur in valves, ports, on cylinder walls, or within the combustion chamber, and it will eventually impede the performance of your vehicle.
Removing this carbon will result in improved acceleration and performance. By improving the performance of your car, you directly improve fuel economy and can enjoy longer periods between trips to the pumps. Engine knock can quickly progress into serious damage on your cylinder walls and pistons, which can be extremely costly to repair.

Anyone try a lacquer thinner soak? I never had to do mine; I check it here and there, and it's been fine. I had forgotten about the head intake runners. I'm guessing with the type of aluminum used and the actual use of the aluminum as an intake manifold runner, not a structural part, the change in "temper" of the aluminum would not be an issue. It don't take much to ruin a gasket seal with small amounts of warpage in a part.
Corsair Veteran Member. This might not count, because technically I didn't do it myself I bought a new intake and installed it.
