Collect the engine components.

• Building a car engine requires several components to power the vehicle.
• Cylinder Block
• Piston
• Connecting Rod
• Crankshaft
• Camshaft 
• Valves
• Timing Belt/Chain
• Oil Pump
• Cylinder Head
• Spark Plugs

Remove the old engine.

One of the first steps when building a new engine is to remove the old one. This is typically done by disconnecting electrical and mechanical connections, draining fluids, and unbolting the engine from the vehicle or equipment installed. Once the old engine is out, the new engine can be installed and connected.

It’s important to take care when removing the old engine to avoid damaging any other components or systems in the vehicle or equipment. This may require specialized tools or equipment and careful planning and execution.

Clean the engine block.

Cleaning the engine block is crucial in building a car engine as it ensures it operates efficiently and effectively. There are several ways to clean an engine block, and the method used will depend on the level of dirt, debris, and grease buildup on the block.

A degreaser or engine cleaner is one common method of cleaning an engine block. The degreaser is sprayed on the block and allowed to sit for a few minutes, breaking down the dirt and grime.

Afterward, the engine block is rinsed with water to remove the degreaser and dirt. Ensuring all the cleaning solution is rinsed off is essential, as any residue left behind can cause engine damage.

Install the pistons, crank, and camshaft.

Building a car engine requires a lot of technical expertise and knowledge of the parts of the engine. 

• Prepare the engine block.
• Install the crankshaft.
• Install the pistons.
• Install the camshaft.
• Install the timing chain or belt.
• Check clearances.

 Install the cylinder head.

• Clean the mating surface.
• Install new gasket.
• Position the cylinder head.
• Tighten bolts.
• Attach other components.
• Check and refill fluids.

Connect the engine components.

Install the followings;

Engine block: The engine block serves as the engine’s foundation. Install it onto the engine cradle and secure it using bolts.

Crankshaft: The crankshaft connects to the pistons and converts the reciprocating motion of the pistons into rotational motion.

Connecting rods: The connecting rods connect the pistons to the crankshaft. 

Camshaft: The camshaft controls the opening and closing of the engine valves. Install it onto the engine block and secure it using cam bearings.

Cylinder head: The cylinder head covers the engine block and contains the valves and camshaft. Install it onto the engine block.

Valve train: The valve train consists of the valves, lifters, pushrods, and rockers’ arms. Install them onto the cylinder head and camshaft.

Oil pump: The pump circulates oil through the engine to lubricate the moving parts. Install it onto the engine block.

Water pump: The pump circulates coolant through the engine to regulate its temperature. Install it onto the engine block.

Install the intake and exhaust manifolds.

• Install the intake manifold.
• Tighten the intake manifold bolts.
• Install the exhaust manifold.
• Tighten the exhaust manifold bolts.
• Connect the exhaust pipes.
• Connect the air intake.
• Check for leaks.

Following these steps, you can install the intake and exhaust manifolds when building a car engine. It is important to ensure that the manifolds are securely fastened and that there are no leaks to ensure optimal engine performance.

Set the timing and valve lash.

Setting the timing and valve lash are important steps in building a car engine, as they can significantly impact the engine’s performance and longevity.

Determine the specifications for the engine’s timing and valve lash. Install the timing chain or belt according to the manufacturer’s instructions. Install the camshaft and adjust the valve lash according to the manufacturer’s specifications. 

Test the engine and make necessary adjustments.

Before testing the engine, you should perform a preliminary inspection of the engine components to check for any obvious defects or damage.

Compression tests can help determine if the engine’s cylinders are working properly. This involves removing the spark plugs and using a compression gauge to measure the compression pressure in each cylinder. A leak-down test is used to identify any leaks in the engine’s valves or piston rings.

Expert Opinion

Building a car engine can be complex and challenging, requiring high technical knowledge, skill, and attention to detail. It involves assembling various components, such as the block, cylinder heads, pistons, crankshaft, camshaft, and other parts, and ensuring they all work together seamlessly to produce power. Hope you have learned how to build a car engine.
