– Ignition system (optional)
**Tools:**
– Socket set
– Wrench set
– Screwdriver set
– Precision measuring tools (calipers, micrometer)
– Engine stand
– Milling machine (optional)
– Lathe (optional)
Step-by-Step Instructions
**1. Prepare the Engine Block and Head**
– Clean the engine block and head thoroughly.
– Inspect for any cracks or damage.
– Bore the cylinders to the desired size and hone the cylinder walls.
– Install the piston rings on the pistons.
– Assemble the pistons and connecting rods to the crankshaft.
**2. Assemble the Valve Train**
– Install the valves, valve guides, and valve springs in the head.
– Adjust the valve clearances to the manufacturer’s specifications.
– Install the camshaft in the head.
**3. Install the Oil Pan and Oil Pump**
– Attach the oil pan to the bottom of the engine block.
– Install the oil pump and connect it to the crankshaft.
