Honda’s timeless K24A gasoline engine was highly acclaimed for its reliability and performance during the period in which it was manufactured, from 2001 to 2016. This powertrain found homes across a number of Honda vehicles, including the Accord, Element, and Odyssey minivan. Not only did it have civilian versions, but Honda offered sport modifications that have since gained fame with racing enthusiasts. Above all else, the K24A is widely recognized as cornerstone of the iconic K-series by Honda that also saw the releases of its predecessors, K20A and K23A engines.

How long will a Honda K24 engine last?
The K-series engine from Honda and Acura is one of the most reliable motor types around, with a track record of over 200,000 miles on their units from the early 2000s with plenty still driving about. Even for those higher revving K24A models, regular oil checks are recommended to ensure it’s long life. With them being both powerful and fuel efficient, K-series engines are ideal for Honda or Acura owners or engine-swappers looking for a reliable motor.
Problems
The K24 engine is an excellent choice for those looking for a reliable and efficient piece of machinery. Spanning across many Honda and Acura models, the K24 has been a popular pick due to its long-lasting abilities and advanced technology. Although it boasts stellar performance, some of the more common issues with this engine are front main seal oil leaks, exhaust cam galling, and timing chain tensioner failure. Variants of this engine may be prone to different problems, however these three are seen most often.
With proper care and maintenance though, the K24 should serve an owner well over its 200K+ miles life-span. It’s not impervious to problems but if looked after it can remain relatively trouble-free for a very long time. Ultimately, the K24 is an ideal choice for people looking for reliable performance at an reasonable cost.
Front Crankshaft Seal Oil Leaks
The Honda K24’s front crankshaft seal, also known as the front main seal, is responsible for sealing the end of the crankshaft to the timing cover by preventing oil from leaking.
- Age and mileage can cause the rubber seal to wear down and leak oil, particularly in K24s with higher mileage (120,000+).
- Symptoms of such a leak include: visible oil leakage; low engine oil; burning or smoking oil smell.
- Replacing this part is relatively inexpensive ($10-30) but can take some time (several hours) to complete.
- Hiring a repair shop to replace it is usually more expensive ($200-400).
Exhaust Camshaft Lobes Wear
Honda K24 exhaust camshaft galling is a common and well documented issue mainly on the K24A1 and K24A4 models.
Symptoms of this issue include clicking noise from valve cover area and loss of power due to decreased valve lift caused by excess friction between cam lobes.
Exhaust cam replacement involves purchasing a new camshaft which can cost up to several hundred dollars, plus labor costs. DIYers may decide to upgrade the camshaft for better performance benefits.
Timing Chain Tensioner
Honda K24 engines use timing chains, which are typically more durable than belts.
The timing chain tensioner is a weak link in the system. It’s commonly an issue on earlier versions and is especially true with modified camshafts or valve springs.
Symptoms of failing K24 timing chain tensioners include rattling/rumbling noises, check engine light, problems starting and internal engine damage.
DIY repair costs for K24 timing chain tensioners range from $100-$400 and can take 6-10 hours, whereas repair shops may cost up to $1200.
