Cleaning the rocker arms in old cars is quite necessary because it is important to keep the engines clean in order to prolong and improve their running condition. In order for the engine to run efficiently, the internals must always be cleaned in order to ensure efficient performance and maximum reliability.
- Socket Wrench Set
- Flat Head Screwdriver
- Rotary Tool with Wire Brush Bit
Step 1: Accessing the Rocker Arms
Open the hood to your engine. Locate the engine cover and remove it by undoing the bolts securing it. Accomplish this using the appropriate size socket wrench. With all the bolts removed, use the flat head screwdriver to pry open the sides of the engine cover to get it off. Once off, you will have access to the rocker arms.
Step 2: Removing the Rocker Arms
There are now about 3 or more bolts holding down the rocker arm. Remove these using the socket wrench set. This will be filled with oil and sludge so be ready for your hands to get dirty. Once undone, carefully lift the rocker arm from its position and set it aside.
Step 3: Soak in Kerosene
Pour around three or four liters of kerosene in a clean bucket and submerge the rocker arm in it. The kerosene will loosen the oil and grime stuck to the rocker arm. Once most of the oil and grime has come off, wipe the arm with the rags to get off as much oil as possible. Let it dry.
Step 4: Detailing
You may notice that not all of the grime came off despite the kerosene. Use the rotary tool with the wire brush to get rid of the stubborn and hardened oil deposits to get your rocker arms squeaky clean.
