Let's start with the intake. This intake was just removed from the blown up 302 engine I show in another thread. The intake looks pretty nice at a glance but it has been painted with aluminum paint. The plan is to use the plastic to remove the paint. Then we will see what the finish other the paint looks like and decide whether the intake needs to be refinished or left as is.
The first step is to remove the oil splash shield from the underside. This can be accomplished with a small hammer and thin chisel of flat blade screw driver. Persuade the blade under the rivet and twist. Repeat. Many guys say that the shield can be left on with plastic since it is just plastic but I like to take them off. It also reveals the date code and since I sell these parts, many guys want to know the date code.
Intake after:
Its hard to see in the pictures since the intake did not look bad or too dirty originally but the intake looks great after blasting. Unfortunately, the plastic does not remove the staining on the cooling ports or water neck area. it also does not remove from from steel fittings. Most customers want a as new looking piece but I am leaving this intake as it is since it would look great on an original car.
Here are 2 videos that may show the change in the intake better:
