1.8L R18A Specs

The 1.8 i-VTEC R18A engine weighs 101 kilograms and has a fairly high displacement – 1799 cm3. Additionally, it accepts multi-point fuel injection, 4 cylinders, 16 valves, aluminum block and cylinder head, and a naturally aspirated structure.

All are complemented by Honda’s unique i-VTEC variable valve timing system – the auxiliary phase starts at 3,500 rpm. In addition, the engineers focused on timing which was operated by a maintenance free chain and an electronically controlled throttle.

What is the result of the final solution? That makes it possible to avoid delaying the reaction to the gas by as much as 16 percent.

The 1.8 i-VTEC R18A engine from Honda has a volume of 3.7 liters. It is best to change the lubricant it contains every 15,000 kilometers, or once a year. New oil must meet the requirements of the 5W-30 standard.

What else should you remember when operating a Japanese gasoline engine? The first should be done after driving 100,000 kilometers by car. From then on, the distance had to be set at 40,000 kilometers. It deserves to be cut in half, especially when the engine is powered by LPG.

1.8L i-VTEC R18A Problems And Reliability

The petrol engine 1.8 i-VTEC R18A likes high speed. However, it can burn engine oil during dynamic driving. Drivers need not worry about this fact. On the other hand, you should regularly check the oil level in the engine. Yes, the engine is aspirated naturally. This way, a little grease won’t damage the turbo.

Unfortunately, at the same time, small amounts of oil can accelerate wear, for example a variable valve timing system, camshaft or even a timing chain tensioner. And replacing these components will definitely be expensive.

Honda’s 1.8 i-VTEC R18A engine is built to last. Its life span is estimated at 300,000 kilometers. However, if the driver remembers about regular servicing and all maintenance procedures, the distance covered can be doubled! What failures do drivers complain about? Symptoms include a mild jolt that does not stop when the engine warms up while driving.

There are several known cases of oil pump replacement in Honda’s 1.8 i-VTEC R18A engine. It mainly relates to end-of-production engines and is generally produced under warranty – due to the low vehicle mileage. In addition, the occurrence is somewhat sporadic, but still worth paying attention to.

What symptoms does the driver complain about? The oil light comes on while you are driving, then a metallic sound starts from under the hood. The engine must be immobilized as quickly as possible, and then the car must be brought to the workshop.

Japanese technology in the late nineties meant expensive spare parts. However, for about two decades, this wasn’t quite true. The “UFO” type Civic, for which the 1.8 i-VTEC R18A engine made its debut, was produced in Great Britain. This means that most replacement elements are available in replacement form at reasonable prices.

Yes, there are more expensive parts. Their prices are usually not higher than the parts installed in competitors’ cars. Hence, this is an amount that drivers will be happy to pay for a trouble-free Japanese car.

Conclusion

Perhaps Honda cars are not the most technologically advanced and have acquired controversial styling over the years. However, they couldn’t deny one thing. They must be civilized. And one of the best pieces of evidence to support this thesis is the 1.8 i-VTEC R18A engine.

How do I summarize it? If the driver maintains his regular service, the engine will pay off with great durability. This is one of the most trouble free petrol engines on the market!
