Honda 3.5L J35A/J35Z/J35Y Engine Specs, Problems & Reliability

Honda 3.5L J35A/J35Z/J35Y Engine

Here in this post, I have gathered information about the Honda 3.5L J35A/J35Z/J35Y Engine from its official website, including its specifications, Problems, and Reliability.

We believe in providing reliable information to our readers, therefore we prefer to obtain information on the Honda 3.5L J35A/J35Z/J35Y Engine from authentic sources.

This article, which has been updated, has all the information you require about the Honda 3.5L J35A/J35Z/J35Y Engine.

The Honda Odyssey first debuted with the J35 gasoline V6 engine in 1998.

The J32A, a 3.2-litre member of the J-series engine family, served as the basis for the development of the new 3.5-litre, six-cylinder J35A.

Over the following years, the engine found its way into a wide variety of large and heavy Honda sedans, SUVs, pickups, and Acura vehicles.

The J35 has seen several revisions over the years, and the latest J35Y version is a big improvement over its forerunner in terms of efficiency, power, and pollution levels.

Variable Cylinder Management Difficulties in a 3.5-litre V6

Considering the wide variety of J35 engines, there is, as we’ve said, a lot to sort through.

Concerns about the VCM technology in Honda’s 3.5-litre V-6 engine are just as contentious. The VCM disables half the engine’s cylinders at light loads to save fuel (3 cylinders).

In theory, this is a fantastic innovation. To reduce pollutants and save fuel when it is not necessary to use full power, three cylinders can be disabled. There seems to be no downside to that.

However, several accounts of VCM system failures and defects have been reported. The J35 VCM gaskets are a common source of oil leaks.

Leaks from the Honda 3.5 VCM unit near the alternator would be disastrous. Oil leaking on the alternator isn’t wonderful news, but it’s not a significant deal if found early.

It appears that the VCM is also to blame for some incidents of excessive oil usage. The problem of excessive oil consumption in models manufactured between 2008 and 2013 prompted a class action lawsuit in 2013.

The early 2005–2007 J35A7 engine was not included; nonetheless, problems have been reported with such VCM systems.

There is evidence that variable cylinder management contributes to issues with engine mounts, torque converters, and spark plugs, in addition to oil consumption.

However, issues do not appear to be as widespread in the latest Honda 3.5 V6 Earth Dreams engine (J35Y). Still, there are many who choose to use workarounds or turn off the feature altogether.

Our impression is that this issue is being exaggerated on the web. However, 3.5L V6 owners should be aware that this is still an issue.

Breakdown of the Timing Belt in a Honda 3.5-liter V6 Engine

Now that we’ve covered VCM, we can move on to the next topics more quickly.

The timing belts on a Honda 3.5-liter V6 aren’t a major source of failure.

Check the manual for your particular J35 engine to be sure the recommended service period of 8 years or 100,000 miles holds true. The J35 timing belt appears to be free of significant defects.

But it’s a crucial part of regular maintenance, so it’s smart to check in on it now and again. Interference power is provided by the 3.5-litre V6.

As a result, the paths taken by the valves and the pistons coincide to some degree. The power and efficiency of interference engines are often higher.

However, the valves and pistons can collide if the timing belt fails or slips excessively. The news is not good.

Valve bending is a common consequence of this phenomenon. The Honda 3.5 V6 may take more hits. Both the initial cost and the labour to fix bent valves are substantial.

The timing belt on a Honda J35 isn’t broken; rather, it’s just a typical wear item that needs to be replaced periodically.

After 6–8 years or 75,000–100,000 miles, the belt should be checked. It’s probably best to stick with the suggested course of action, even if everything seems fine.

How much HP does a 3.5 VTEC engine have?

Maximum horsepower is 280 at 6000 rpm (SAE net), while peak torque is 260 lb-ft at 4700 rpm (SAE net).

Delivering the fuel-air combination directly to the combustion chamber improves efficiency and power production, and piston-crown cooling allows for a greater compression ratio to be set.

How many miles will a Honda 3.5 V-6 last?

Regular and thorough maintenance can alleviate or prevent many of these issues.

Tuning Pro advises using high-quality oils, replacing fluids at the appropriate intervals, and addressing problems as soon as they arise.

Without much maintenance, J35 engines have routinely surpassed 200,000 miles.

How can I make my j35 faster?

Head porting could potentially increase efficiency. Use J32A2 components such as heads, pistons, and an intake and exhaust system in place of your current units.

If this happens, your J35 will be reduced to only its short block. The combined effect of all these performance upgrades is an extra 320–330 horsepower at the flywheel.

Do J-series engines have VTEC?

The SOHC 4-valve designs included in the J-series engines all use gasoline and have VTEC variable valve timing.

Honda’s Variable Cylinder Management (VCM) technology is a distinctive feature of a few J-family engine variants.

Under light loads, the system uses VCM to turn off a bank of cylinders, turning the V6 engine into a straight-three engine.
