The Nissan KA24DE engine is a four-cylinder engine produced by Nissan Motor Company. It was first introduced in 1988 as the successor to the Nissan Z engine and was used in a variety of Nissan vehicles, including the 240SX, Altima, and Frontier pickup truck.
The KA24DE engine features an iron block and aluminum head, double overhead camshafts, and multi-point fuel injection. It is known for its durability and reliability, making it a popular choice for both street and race applications.
The engine’s name, “KA,” stands for “K-series engine, A-series block.” The “24” represents the engine displacement of 2.4 liters, and the “DE” stands for “dual overhead camshaft, electronic fuel injection.”
Over the years, the KA24DE engine has undergone a number of changes and improvements. In 1991, Nissan introduced the single-cam KA24E engine, which was less powerful but more fuel-efficient than the KA24DE. In 1998, the KA24DE was updated with a revised cylinder head, increased compression ratio, and improved airflow.

Nissan KA24DE Engine Problems: A Comprehensive Guide
The KA24DE engine is a robust and durable engine in its stock form. Its cast iron block and aluminum cylinder head can withstand a fair amount of abuse before issues start to appear. The engine also has a relatively low compression ratio, which benefits its longevity by reducing the internal pressure. However, when heavy performance modification is introduced, additional problems can arise. In this article, we will discuss the most common KA24DE engine problems, their symptoms, and solutions.
Valve Cover Gasket Failure
A blown or failing valve cover gasket is one of the most common KA24DE issues. While factors like aggressive driving and over-revving can contribute to the failure of a KA24DE valve cover gasket, old age is the most common destroyer of the part. With most US-spec KA24DEs approaching 30-years in age, a valve cover gasket replacement is a smart investment. Some of the most common symptoms of a faulty valve cover gasket include a burning oil smell, a dirty valve cover from leaking oil, and engine running rough or misfiring.
Fortunately, a KA24DE valve cover replacement is a straightforward and inexpensive fix. The valve cover gasket can still be purchased from Nissan for under $20. The replacement job also requires the spark plug seals to be replaced to prevent oil from leaking into the spark tubes. Spark plug seals can also be purchased from Nissan for a cost of around $30. Most KA24DE owners say that the job takes about an hour, even for inexperienced owners.
Faulty Distributor
Another frequently cited issue for KA24DE engines is a failed distributor. Age is the most common reason that KA24DE distributors fail. Symptoms of a malfunctioning distributor include rough engine idle, difficulty starting, and loud whining noise.
Replacing a KA24DE distributor is another simple and cheap job. KA24DE distributors typically cost somewhere in the ballpark of $250 for an OEM-spec unit. Once again, if you have even rudimentary hands-on experience, replacing a KA24DE distributor should be a piece of cake. Replacing your KA24DE’s distributor is a quick and easy way of ruling out spark/misfire issues.
Timing Chain Rattle
KA24DE engines often suffer from extremely pronounced timing chain rattle. This can be a serious annoyance and potentially lead to issues down the line if neglected. The main cause of this annoyance is the engine’s overall construction. Due to the fact that the KA24DE is a 4-cylinder with a flat-plane crank, it has an imperfect secondary balance. The most common symptoms of timing chain rattle are a “marbles in a tin can” sound and persistent squeaking or rattling from the valve cover area.
Since the KA24DE is an interference motor, a timing chain issue can cause serious damage to the engine’s internal components. If you notice an odd sound coming from the valve cover area, it should be assessed and addressed sooner rather than later.
Ultimately, there are a few noted solutions to fix the KA24DE’s timing chain rattle issue. In quite a few cases, the noise is caused by a broken or misaligned top or side timing guide that has wedged itself into a problematic position. If the noise still persists following the removal of the timing guides, there is likely an issue with another component of the timing chain system. The next steps would be to replace the upper chain, tensioner, and guide. More than likely, that will solve the issue.
The approximate prices for a Nissan KA24DE engine:
| Condition | Price Range |
|---|---|
| Brand New | $2,500-$4,000 |
| Remanufactured | $1,500-$3,000 |
| Used, Low Mileage | $800-$1,500 |
| Used, High Mileage | $500-$1,000 |
Please note that these prices are approximate and can vary widely depending on various factors such as the specific year and model of the engine, the condition of the engine, and the location and availability of the engine. Additionally, the cost of installation and any necessary modifications or upgrades are not included in these prices. It’s important to thoroughly research and inspect any engine before purchasing to ensure its quality and suitability for your needs.
