Building an engine in My Summer Car can feel like solving a greasy jigsaw puzzle with a wrench, but once you understand the flow and tool requirements, the process becomes both manageable and satisfying. In this guide, Victor walks us through a complete engine assembly — from crankshaft to carburetor — with clear instructions and tuning tips for optimal setup. Follow this guide carefully, and you’ll have a perfectly functional (and maybe even painted) engine ready to power your Satsuma.

Step-by-Step Engine Assembly

1. Crankshaft Installation

• Start with the engine block and rotate it to the side.
• Insert the crankshaft into place (look for the green check mark).
• Install the main bearings.
• Use the 9mm spanner to tighten all six crankshaft bolts.

2. Pistons and Oil Pan

• Rotate the block upright.
• Insert all four pistons.
• Rotate the block again and tighten piston bolts using a 7mm spanner.
• Attach the oil pan.
• Tighten with both 13mm and 7mm spanners.

3. Camshaft and Gear

• Insert the camshaft.
• Tighten using the 5mm spanner.
• Install the cam gear and align the timing arrows.
• Use the 10mm spanner to secure it.
• Rotate the cam gear fully until its arrow aligns with the engine block’s marking. This is critical — a mismatch will destroy your engine.

4. Timing Assembly

• Add the timing chain.
• Install the timing cover and tighten with a 6mm spanner.
• Attach the water pump, using a 7mm spanner.
• Add the crankshaft pulley, secured with an 11mm spanner.

• Mount the engine plate.

5. Clutch and Flywheel

• Install the flywheel, tighten with a 7mm spanner.
• Assemble the clutch: combine pressure plate, clutch disc, and cover plate.
• Bolt the clutch assembly with a 6mm spanner.

6. Gearbox and Drive Gear

• Before mounting the gearbox, install the inspection cover.
• Bolt the gearbox using 7mm and 10mm spanners.
• Add the drive gear and tighten with a 6mm spanner.

7. Cylinder Head Assembly

• Place the head gasket.
• Install the cylinder head, secured with a 7mm spanner.
• Add the rockers, and use an 8mm spanner to tighten.

8. Tuning the Rockers

• Grab a screwdriver.
• Scroll down on each rocker screw until it stops moving, then scroll up seven clicks.
• Repeat for all screws.

9. Cover Components

• Attach the rocker cover, using a 7mm spanner.
• Install the water pump pulley, starter motor, and oil filter:
  • Water pump pulley – 7mm
  • Starter – 7mm
  • Oil filter – scroll up with mouse to tighten

10. Ignition System and Spark Plugs

• Install spark plugs and use the spark plug wrench.
• Mount the distributor.

11. Tuning the Distributor

• Scroll down until the distributor stops moving.
• Then scroll up 27 clicks.
• Tighten the single screw using the screwdriver.

12. Belt and Alternator Adjustment

• Install the alternator belt.
• Adjust alternator:
  • Scroll down until it stops.
  • Then scroll up 2 clicks.
• Tighten alternator screw with a screwdriver.

13. Fuel Delivery and Intake

• Install the fuel pump – 7mm spanner.
• Add headers and the carburetor – 8mm spanner.

14. Tuning the Carburetor

• With a screwdriver:
  • Scroll up 50 clicks.
  • Then scroll down 23 clicks.

15. Final Touches

• Install the air filter – tighten with a 6mm spanner.
• Optional: Paint the engine using a spray can. Equip it by pressing F and apply color to the block, rocker covers, and air filter.
