Used Honda J35 Engines for Sale - Specs, Reliability, and Buying Guide

Overview of the Honda J35 Engine

The Honda J35 engine is a 3.5L V6 gasoline engine that was first introduced in the 2002 Honda Odyssey. This new J-series engine replaced the previous C-series engine and featured gasoline direct injection technology, variable cylinder management, and intelligent variable valve timing to optimize power and efficiency.

The J35 engine has gone through several iterations over the years but remains a staple in many Honda and Acura vehicles. In this article, we’ll take a closer look at the history and evolution of the J35, its key features and technologies, where it’s been used, and what to know if you’re considering purchasing a used J35 engine for sale.

Generations of the J35 Engine

There have been three primary generations of the J35 engine:

• First generation (2002-2008) - Found in vehicles like the Odyssey, Pilot, Ridgeline. Power output ranged from 244-268 hp.
• Second generation (2009-2014) - Improved power and efficiency. Used in vehicles like the Accord, Odyssey, Pilot. Power output from 250-281 hp.
• Third generation (2015-present) - Further refinements to power and efficiency. Seen in the Odyssey, Pilot, Ridgeline. Power output from 280-310 hp.

Key Features and Technologies

Here are some of the notable features and technologies used in the J35 engine:

• Gasoline Direct Injection (GDI) - Fuel is injected directly into the cylinders rather than the intake ports for improved efficiency and performance.
• i-VTEC - Honda's intelligent Variable Valve Timing and Lift Electronic Control system optimizes valve timing and lift for power and efficiency.
• Variable Cylinder Management (VCM) - Cylinders can be deactivated under light load conditions to save fuel.
• Drive-by-Wire Throttle System - Electronic rather than mechanical throttle control for smoother, more precise throttle inputs.
• Aluminum Alloy Block and Cylinder Head - Lightweight construction reduces weight for better fuel economy.

Honda and Acura Vehicles with the J35 Engine

Here are some of the main applications of the J35 engine in Honda and Acura vehicles:

Honda

• Honda Odyssey - All generations since 2002
• Honda Pilot - All generations since 2003
• Honda Ridgeline - All generations since 2005
• Honda Accord V6 - 2008-2012 models
• Honda Inspire/Saber - Japan/China market sedans

Acura

As you can see, the J35 has powered a wide range of popular Honda and Acura vehicles over the past 20 years. It’s been the trusted V6 option for models like the Odyssey, Pilot, Ridgeline and TL.

Buying a Used J35 Engine

With millions of J35 engines on the road, it’s not hard to find used ones for sale. Here are a few tips for shopping for a used J35 engine:

• Try to find one with lower mileage and service records if possible.
• Confirm the exact engine code - there are variations between J35A3, J35A5, J35A6, etc.
• Inspect overall condition - look for leaks, damage, abnormal wear and tear.
• Do a compression test to check cylinder health if possible.
• Listen to engine sound for any knocking or ticking noises.
• Verify OEM Honda manufacturer or rebuilt to OEM specs.
• Ask about any warranty or guarantee on the used engine.
• Calculate the total cost with install labor if not doing DIY.

Used J35 engines can typically be found through auto salvage yards, online classifieds or auction sites, mechanics shops, or import/JDM motor retailers. Prices can vary widely based on mileage, condition, and source but expect to pay anywhere from $800 on the low end to over $3,000 for a lower mileage J35.

Things to Keep in Mind

Here are a few other things to keep in mind when shopping for a used J35 engine:

• Higher mileage engines may need timing belt/water pump replacement.
• Watch for signs of oil leaks in VTEC system, timing cover, etc.
• Aftermarket modifications could negatively impact longevity.
• Expect to replace accessories like alternator, power steering pump, etc.
• Repairs costs quickly add up - be sure engine is good quality upfront.

With proper inspection and by doing your homework on the J35's history, you can find a quality used engine that still has plenty of life left. But higher mileage or poorly maintained J35's can end up costing more in repairs down the road.

Honda J35 Engine Specs

Here is an overview of key specifications for the Honda J35 engine across different generations:

The J35 engine has an aluminum alloy cylinder block and cylinder head with a 60 degree V angle. It uses a timing chain rather than belt. The compression ratio also increased from 10.0:1 to 11.2:1 over the generations to improve efficiency.

Finding the Right J35

When searching for a J35 engine, use the specs above to match the generation you need for your vehicle. The newer 2nd and 3rd gen engines offer more horsepower and torque, but the 1st gen can still be a quality option at a lower price point when shopping used if mileage is lower.

The J35's Reliability and Lifespan

The Honda J35 is generally regarded as a very reliable engine. Typical problems are minor issues like oil leaks from seals and gaskets. Some have reported issues with oil consumption or fouled plugs on higher mileage or modified engines.

With proper maintenance, J35 engines are regularly seeing over 200,000 miles of reliable service. Timing chain and tensioners may need servicing around this mileage. Use of the recommended engine oil and frequent changes are important.

It's not uncommon to find J35 engines exceeding 300,000+ miles. Overall, the J35 establishes Honda's reputation for building long-lasting, high-quality engines.

Longevity Tips

To maximize the lifespan of your J35 engine:

• Follow the maintenance schedule in your owner's manual.
• Use Honda recommended engine oil - look for "Energy Conserving" on the API service label.
• Watch oil levels - these engines can consume some oil over time.
• Use OEM or high quality aftermarket replacement parts.
• Clean intake valves and injectors at higher mileages.
• Don't neglect cooling system maintenance.
• Avoid excessive engine modifications.

The J35 responds well to regular maintenance and care. Follow these tips and your engine can provide many years and miles of reliable performance.

Is the J35 Engine Reliable and Worth Buying Used?

The Honda J35 engine has proven itself to be a very reliable design capable of reaching high mileages when properly maintained. It offers a good blend of power, efficiency, and real world dependability.

For those looking for an affordable replacement V6 or upgrading their Honda or Acura, a good condition used J35 can a worthwhile investment. As always, be sure to perform due diligence on any engine you're considering - inspect condition, verify mileage, service history, run a compression test, etc.

But the J35 has an excellent track record thanks to Honda engineering. For many owners, a J35 swap to gain more horsepower while retaining OEM-level reliability is a smart play. And even at high miles, a well cared for J35 will likely have plenty of life left in it.

The Bottom Line

If you can find a used J35 engine from a trusted source and have it thoroughly inspected, it can be a great and affordable option versus a new crate engine. The J35's combination of technology, real world reliability, available power, and aftermarket support make it a compelling choice - especially for Honda and Acura owners looking to repower or upgrade.
