Engine failure is inevitable because as the car ages, its parts also become defective and dysfunctional. This can also happen sooner than most car owners think especially if they don't provide regular and proper maintenance. Replacement is usually the best option that car owners have to restore efficient road performance. If some of the engine parts are still in good condition they can just get a new Engine Long Block. This is an almost-complete engine assembly because it already contains the short block and the cylinder head. The short block is already made up of vital engine components like the crankshaft and piston assemblies. If car owners opt for the Engine Long Block, they won't need to go around searching for a lot of other parts since it's almost complete. Due to this, owners can immediately proceed to its installation. However, they must remember that engine repair and replacement is a complicated job to perform. If their knowledge is not sufficient, it would be better for them to get the services of an auto technician. Aside from complicated installation, car owners also have to be ready for the cost if they decide to invest on a long block. Since it's an almost complete assembly, it also costs more compared to the short block. However, every cent they spend is all worth it because of the convenience offered by the Engine Long Block.
Things to Consider When Choosing an Engine Long Block
A long block is an engine sub-assembly that's largely used when doing an engine overhaul. Nearly all parts of the engine are included and pre-assembled in a long block, including the attachments and wirings. These parts include the manifolds, cylinder heads, timing gears and bearings, valves, guides and springs, and camshaft.
Why is it better to invest in a long block than in a short block?
Both sub-assemblies are composed of the different parts required to run a vehicle. The main difference is the cylinder heads. In most cases, the long block is considered as the complete version of the short block and is more cost-efficient. Short blocks require additional parts and longer installation time, so they're basically more expensive than long blocks. Your engine will also achieve better performance with a long block, as it is already in a complete state and all parts are brand new. Aside from that, the components included in the sub-assembly will also wear out evenly, minimizing replacement costs.
What are the things to consider when choosing a long block?
The first is, of course, the cost. Additional external long block parts are cheaper compared to internal short block components. Labor charges also cost less, as this sub-assembly requires shorter installation time. Engine long blocks are priced at around $1,500 to $5,000. Add to that amount the labor cost if a mechanic will do the installation for you.
Like any other auto part, not all long blocks will work well with your vehicle's make and model. Although it is already a complete assembly, you have to make sure the transmission system and electronic control unit of your vehicle are compatible with the long block you wish to install. Check the compatibility of the shift linkages, sensors, axles, wiring harnesses, and mounts first before purchasing a new long block.
DIY Engine Long Block Assembly
Long-block engines are already expensive enough without mechanic charges. As nearly complete sub-assemblies, these engines usually cost over a thousand dollars. Long blocks have all the works compared to short blocks, and that's why they're generally pricier. If you want an engine overhaul, then long blocks are highly recommended. Cylinder heads, valves, camshaft, timing gears, and manifolds are just some of the parts included in a long-block engine. If you want to save money on labor costs, assemble the long-block engine yourself. Here are the things you'll need and the steps to follow in assembling a long-block engine:
Difficulty level: Difficult
Tools and parts required:
- Power steering pulley puller
- Engine hoist
- Engine stand
- Tool kit
- Engine sump pickup tube
- A/C compressor mounting bracket
- Intake manifold and gasket
- Exhaust manifold and gasket
- Timing cover and gasket
- Valve cover and gasket
- Water pump and gasket
- Thermostat and gasket
- Crankshaft pulley
- Alternator mounting bracket
- Power steering pump mounting bracket
- Gasket sealant
Step 1: Lift the long block using the engine hoist and mount it on the engine stand. Detach it from the engine hoist.
Step 2: Connect the flywheel to the crankshaft. Next, set the intake manifold assembly on its corresponding gasket and bolt it into place. Torque the bolts to factory specifications using a torque wrench.
Step 3: Apply a gasket sealant on the mating surface of the valve cover and insert the corresponding gasket. Mount the valve cover on the cylinder head and bolt it into place.
Step 4: Bolt the exhaust manifold and gasket together. Tighten and torque according to factory specs.
Step 5: Do the same process to the timing cover, water pump, and thermostat. Remember to tighten and torque accordingly.
Step 6: Connect the crankshaft to the crankshaft pulley. Next, put adequate lubrication on the oil filter gasket and rotate it on the oil filter mount. Tighten the oil filter by hand.
Step 7: Turn the engine upside down to easily attach the oil sump tube. After applying gasket sealant on the oil pan's mating surfaces, position it on the engine block. Make sure the gasket is secured in place and that all holes are aligned properly between the pan, gasket, and block. Hand-tighten the oil pan bolts and torque to factory specifications.
Step 8: Rotate the engine back up. Attach the mounting brackets of the alternator, A/C compressor, and power steering to the engine, but don't tighten the bolts.
Step 9:Install the starter. The assembly of your newly purchased long-block engine is now complete.
