Mastering Your My Summer Car Engine Build

Building Your First Engine in My Summer Car: A Comprehensive Guide

Embarking on the journey of building an engine in My Summer Car can be a daunting, yet incredibly rewarding, experience. This guide will walk you through the intricate process, from gathering your components to the final triumphant roar of your newly assembled powerhouse. We'll delve into the critical steps, highlight key parts, and offer advice to ensure your engine not only runs but thrives.

Preparation is Key: Setting Up Your Workspace

Before you even think about touching a bolt, proper preparation is paramount. The engine assembly takes place in the garage, specifically on the engine stand positioned by the wall. All the necessary engine parts are scattered around the back of the garage, both on shelves and the floor. However, some crucial items, like the alternator belt and oil filter, must be purchased from the store. Don't fret if the engine components fall during assembly; they are designed not to break. Make frequent use of the rotation feature to gain optimal access to every screw and bolt. For efficiency, place your toolbox on the workbench for quick and easy access to your tools.

The Heart of the Machine: Block, Crankshaft, and Camshaft

The foundation of any engine is its block. Start with the engine BLOCK, the main housing, and the CRANKSHAFT, the rotating assembly that converts reciprocating motion into rotational motion. These two must be joined at your workstation. This connection requires three MAIN BEARINGS. Each main bearing is uniquely numbered and must be fitted into its specific location on the outer parts and the centre of the block. The crankshaft then slots into the block, supported by these three bearings. Each bearing is secured with two nuts of size 9, which are tightened using a 9mm wrench. Following this, insert the CAMSHAFT into the block and secure it with two nuts of size 5. The camshaft is initially supported by two bolts, which you'll fine-tune later.

Introducing the Pistons and Cylinder Head

Next, we introduce the four PISTONS. Carefully insert each piston into the cylinder bores of the engine block, ensuring they are positioned adjacent to the crankshaft. Each piston is secured with two nuts of size 7, which are accessible from the crankshaft side. The valves, which sit atop the pistons, require two 7mm screws each for their respective mounts. Now, place the HEAD GASKET onto the engine block. This vital component creates a seal between the block and the cylinder head. Crucially, the head gasket does not require any screws. The CYLINDER HEAD is then placed on top of the head gasket. This assembly is secured with ten nuts, all of size 7mm.

Valvetrain Assembly: Rocker Shaft and Cover

With the cylinder head in place, it's time to install the valvetrain components. The ROCKER SHAFT, a long shaft that actuates the valves, needs to be attached to the cylinder head. Secure this with five nuts of size 8mm. The valves will now protrude upwards from the head. You can tighten the rocker shaft with an 8mm wrench. The exposed valves are then covered by the ROCKER COVER, which is fastened with six nuts of size 7mm.

Managing Exhaust and Intake: Header and Carburettor

Attention now turns to the engine's breathing system. Attach the exhaust manifold, commonly known as the HEADER, to the engine. This is tightened with five nuts of size 8mm. Following this, the CARBURATOR, responsible for mixing fuel and air, is attached to the header. Secure the carburettor with four nuts of size 8mm.

Timing is Everything: Camshaft Gear, Timing Chain, and Cover

Precision is critical when it comes to engine timing. First, install the CAMSHAFT GEAR and the water pump assembly. Rotate the engine to its side and attach the camshaft gear. This is secured with a 10mm wrench. Important Note: Proper alignment of the camshaft gear is essential. Locate the timing mark on the engine block – it's a blade pointing roughly to the 10 o'clock position. You'll find a similar mark on the camshaft gear itself. Using the same 10mm wrench, slowly rotate the gear with your mouse wheel until the marking on the gear precisely aligns with the marking on the engine block. Once aligned, fit the TIMING CHAIN and then cover this mechanism with the TIMING COVER. The timing cover is secured with six screws of size 6mm. The timing chain itself does not require screws. Finally, mount the CRANKSHAFT PULLEY onto the timing cover and tighten it with a single screw of size 11mm.

Cooling and Accessories: Water Pump and Pulleys

The engine needs a cooling system. Install the WATER PUMP above the crankshaft pulley assembly. This is secured with five nuts of size 7mm. Mount the WATER PUMP PULLEY onto the water pump and fasten it with four screws of size 7mm.

Ignition and Fuel Delivery: Distributor, Oil Filter, and Fuel Pump

Now, let's get the engine ready to spark and receive fuel. Rotate the engine so the wider side faces you. Install the DISTRIBUTOR, the ignition timing device. Use a screwdriver to tighten this part. You will later need to adjust the ignition timing using this component. It's time for the OIL FILTER. It is strongly recommended to use a new unit purchased from the store, as used parts from the garage often have significantly reduced condition. The oil filter typically mounts using the mouse wheel, without the need for tools. Lastly, mount the FUEL PUMP next to the oil filter and secure it with two nuts of size 7mm.

Ignition Sequence: Spark Plugs

The final step before external components is to install the SPARK PLUGS. Insert these into the four designated holes in the cylinder head. You'll find them in a spark plug box that needs to be purchased from the store. Press the 'F' key each time to remove a single spark plug from the box. These can be tightened into the engine block using a special SPARKPLUG WRENCH. Remember to press 'F' four times to retrieve all four spark plugs.

Power Generation: Alternator and Belt

The ALTERNATOR generates electrical power for the car. Install it next to the water pump. It's secured with two nuts: one of size 7mm and the other of size 10mm. There's a regulating screw, but it's best not to adjust this just yet. Now, place the alternator belt onto the prepared pulleys. Ensure you remain in 'hands-on' mode for this. Tighten the tensioner roller to its furthest right position. Then, using the mouse wheel, 'unscrew' it by two clicks. Finally, tighten the regulating screw with a screwdriver to secure the belt's tension.

Sealing and Drivetrain: Oil Pan, Engine Plate, and Flywheel

The engine needs an oil reservoir and a connection to the transmission. Attach the OIL PAN to the bottom of the engine block. This is secured with eight nuts of size 7mm and one larger nut of size 13mm, which also serves as the drain plug for oil changes. Ensure it is tightened as much as possible. Rotate the engine block to its narrower side and attach the ENGINE PLATE. Next, install the FLYWHEEL, the heavy rotating disc that smooths out power delivery. Secure it with six bolts of size 7mm.

Clutch Assembly and Starter Motor

The clutch system connects the engine to the gearbox. Assemble the three clutch components: the CLUTCH COVER PLATE and the CLUTCH DISC. These parts connect without screws. Mount this assembled clutch unit onto the flywheel and secure it with six screws of size 6mm. Finally, attach the STARTER motor, responsible for initiating the engine's rotation, and secure it with two nuts of size 7mm.

Connecting to the Drivetrain: Gearbox and Drive Gear

The final major engine component is the GEARBOX. Attach this substantial unit to the engine block and secure it with six screws of size 7mm and one screw of size 10mm. Mount the DRIVE GEAR onto the gearbox and tighten it with seven screws of size 6mm.

Expert Advice: Rebuilding for Longevity

For new players, a proactive approach to engine health is highly recommended. Instead of just assembling, consider a full rebuild with new parts. This involves removing the engine, disassembling it down to the crankshaft, and replacing all wearable components. While this might seem costly (around 6600 marks for essential parts excluding the oil pan and block), it significantly extends your engine's lifespan, often pushing it well over 100,000 kilometres. While the head gasket can still wear over time and require replacement, a rebuilt engine bypasses the common issues of low-condition parts leading to premature failure. Attempting to repair existing parts often results in only around 50% condition, making a full replacement a more reliable long-term strategy.
