The Honda J32 3.2L V6 engine made its debut in the 1999 Acura TL. It produced solid power levels for a V6 of its time, making the TL, especially the Type-S models, popular for performance. It also came with strong reliability, capable of surpassing 250,000 miles without any serious problems.

In this guide we’re going to cover everything about the J32. From specs to performance and tuning potential to common problems and reliability.

Vehicle Applications

  • 1999-2003 Acura TL (J32A1)
  • 2001-2003 Acura CL (J32A1)
  • 1999-2002 Honda Inspire (J32A1)
  • 2001-2003 Acura CL Type-S (J32A2)
  • 2002-2003 Acura TL Type-S (J32A2)
  • 2004-2008 Acura TL (J32A3)

J32 engines are best known for their use in the Acura TL and TL Type-S models from 1999-2008. It’s also in the Japan-based Honda Inspire. Lastly, J32A1 and J32A2 engine variants are in the Acura CL and CL Type-S, respectively. These models were only made through 2003.

  • 2004 Acura TL: 0-60 in 5.7 seconds, 14.4 @ 99mph 1/4 mile

Performance data for the Acura TL 3.2L V6 isn’t anything eye-popping by modern standards. Although, for the era these were pretty good results, especially for the J32A3 in 2004+ models. We don’t have much else to say about stock performance, but let’s take a look at aftermarket potential.

Aftermarket Potential

Many understand naturally aspirated engines are pretty limited in power and torque. The same concept applies to the Acura J32 engine. Without a turbo or supercharger kit these engines don’t have much extra to offer. A few bolt-ons like an intake, exhaust, tune, and headers may help net an extra 10-30 horsepower.

However, the original J32 engine does have some potential. Exhaust, intake, intake manifold, and camshaft mods were major upgrades to the J32A2 allowing for 260 horsepower. Similar mods can boost the earlier variants around these levels if not a bit further with the right upgrades and a tune.

Those wanting anything much beyond 280-290hp will need to look to forced induction. It’s not cheap to go this route and many prefer the older B and K series engines for boost. That said, there are some awesome, unique builds of the J32 engine. You’ll simply need a deep wallet and a lot of patience/knowledge to get the right build.

Honda J32 Engine Problems

  • Rear main seal
  • Timing belt
  • Oil leaks

1) Rear Main Seal Leaks

Rear main seal leaks may be the single most common issue with the Honda J32 engine. It’s fair to say this is a fairly common problem on many different engines so the 3.2L V6 isn’t alone here. Oil leaks from the rear main seal are also mostly age and mileage related issues. We’re not familiar with any serious design flaws that cause this leak.

Anyways, oil leaks are a topic we’ll be circling back to for good reason. Honda J32 engines are about 14-23 years old now. Age and mileage is tough on gaskets, seals, rings, plastics, etc. Parts become brittle and begin cracking with age. That’s the exact issue at hand when it comes to the Honda 3.2 V6 rear main seal leaks.

Main seals aren’t the only oil leaks, though. Why are we singling out the rear main seal? Not only is this problem fairly common, but it can also be an expensive repair. On the Acura TL the transmission must be dropped to remove the rear seal. Cheap part but labor can add up quickly.

2) Timing Belt Problems

The timing belt isn’t something we consider a true issue on the Acura J32 3.2L engines. It’s still an important topic and something we felt was good to discuss. Timing belts are a standard maintenance item. Acura TL models with the J32 call for belt replacement every 8 years or 105,000 miles. Whichever comes first. It’s rare to see failures before that mileage (and still pretty rare up to 125,000+ miles).

However, Honda J32 engines are interference engines. There is overlap in the area the pistons and valves travel. If a timing belt snaps or slips the 3.2L V6 pistons and valves may contact each other. In this situation you’ll likely end up with some bent valves as a best case outcome. That’s already bad enough but complete engine failure can occur. Either that or the damage is so extensive it doesn’t make sense to fix.

Point is – don’t overlook the timing belt and ensure you’re keeping up with the maintenance schedule. Timing belt failures don’t happen often in general, but it can be bad if it happens. Keep up with belt replacements and issues are nearly unheard of.

3) Oil Leaks

Discussing general oil leaks on the Honda J32 V6 engine is a quick topic. This is somewhat duplicate to the rear main seal problems from above. Rubber gaskets, seals, and o-rings simply wear down with age and mileage. They become brittle, begin cracking, and then oil leaks develop.

Outside of the rear seal also look out for the oil pan gasket, valve cover gaskets, and front main seal. This isn’t an exhaustive list, but they’re a few of the most common areas for J32 engine oil leaks.

Oil leaks aren’t the only thing. Engines are subject to many parts that wear down with age and mileage. It’s not always just about mileage, either. We’ll circle back to this in the reliability topic in a moment. It’s simply important to remember the Honda J32 3.2L V6 is an older engine that’s prone to issues due to that fact.

Acura TL J32 Reliability

Is the Honda & Acura J32 3.2 V6 engine reliable? Yes, we believe the engine earns above average marks for reliability. When it comes to the engine itself there aren’t really any major common problems. Rear main seal leaks are common with older age and high mileage. The same can be said for a few other oil leaks and occasional coolant leaks.

Otherwise, keep up with maintenance and the Honda J32 is an excellent engine. Things like timing belts can cause expensive damage, but it’s extremely rare if you stay on top of belt replacements. Of course, do all of the other basics like changing fluids on timing, using quality oils, and fixing problems in a timely manner.

Keep in mind – we’re talking about a 13-22 year old engine. Many J32 engines likely still have plenty of life left in them, but older engines are prone to their share of problems. Fortunately, most issues are inexpensive and relatively simple to repair. It’s not uncommon to see the J32 hold up beyond 250,000 miles with few problems along the way. Not too bad for longevity.

  1. best bolt on mods for the J32a2 type-s motor for racing purpose only. say we are looking to gain 50-75 hp while remaining N/A or is it just easier to take the turbo penalty?

  2. My tl has lasted so far 260,000 and still running but I do want to upgrade power wise any options anyone can give me.

  3. I see you spend much time talking about oil leaks in this motor. Im quite surprised that you neglect the issue of “phantom oil disappearance” No visible oil leaks. No smoke upon starting engine cold. Have 2006 RL with 78k on it. Engine is tight. no leaks…nothing wet. Yet Oil light came on and upon checking it was down 3 quarts of oil. This after only 1000 after oil change. Put in the required 3 quarts and drove 9 miles to park car at home. Next day check oil again and it is already down 3/4 quart. No leak….no smoke. Im hearing there is an issue with VTEC “sucking up the oil” but with no explaination of how that can happen or what would happen to the oil from there. Any ideas on what this means ? Also hearing that clogged PCV valve is the issue. Again, any ideas about that? Customer bought car new. He is now 76…..Ive know him 30 years and i assure you he is no hot rod. It was his daily driver to work and for errands. I look forward to your opinion on this. Thanks
