The Honda J32 3.2L V6 engine made its debut in the 1999 Acura TL in the form of the J32A1. A few other J32 variants followed until its final production in 2008. Horsepower varies from 225-270 hp. Pretty stout numbers for a relatively small V6 of the early 2000’s era. No engine is flawless, though, and that applies here too. In this guide, we discuss Honda J32 3.2L V6 engine problems, reliability, specs, and more.

What Cars Use the J32 Engine?

Honda/Acura 3.2 V6 engines are in the following years and models:

  • 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, which is similar to the Acura TL models. Lastly, J32A1 and J32A2 engines are in the Acura CL and CL Type-S, respectively. These models were only made through 2003.

Honda J32 V6 Specs

Specs for the Acura J32 engine are as follows:

EngineHonda J32
Displacement3206cc (3.2L)
Head/Block MaterialAluminum
ValvetrainSOHC VTEC
Bore x Stroke89mm x 86mm
Compression Ratio9.8:1 or 10.5:1
Horsepower225-270 HP
Torque (lb-ft)216-238 lb-ft

These are pretty standard specs for a J-series Honda engine. Nothing jumps out as being overly special when looking into deeper J32 specs, either. Honda 3.2L V6 engines use an aluminum block and head to keep weight down. The SOHC VTEC design allows for efficient low-end performance with more power up-top.

Add it all together and the engine is good for 225 to 270 horsepower. J32A1 engines offer 225hp and 217 lb-ft. Acura Type-S J32A2 engines see a boost to 260 horsepower and 232 lb-ft of torque. Extra power comes from an improved intake, exhaust, and camshaft.

The latest J32 engine – the J32A3 – powers 2004 to 2008 Acura TL models. Honda initially rated the engine at 270hp. However, it was soon lowered to 258hp due to changes in SAE power testing methods. Despite the different power rating the engines are identical.

Acura 3.2L V6 Performance

We typically avoid getting into specific performance details. Most engines are in too many various cars to get specific. However, it’s a bit easier with the J32 V6 since it’s primarily in the Acura TL and TL-S. Below are a few specs from Car & Drivers testing of these models:

  • 2002 Acura TL: 0-60 in 7.4 seconds, 15.9 @ 90mph 1/4 mile
  • 2002 Acura TL Type-S: 0-60 in 6.2 seconds, 14.8 @ 96mph 1/4 mile
  • 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.

Acura TL J32 Aftermarket Potential

Many understand naturally aspirated engines are pretty limited in power and torque. The same concept applies to the Acura J32 V6 engine. Without a turbo or supercharger kit the J32A2 and J32A3 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. It’s not more capable than the later engines; the J32A1 simply has a lower starting point. Exhaust, intake, intake manifold, and camshaft mods were major upgrades to the J32A2 allowing for 260 horsepower. Similar mods can boost the Honda J32 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 3.2 V6 Engine Problems

A few of the most common issues with the Honda/Acura TL J32 3.2L V6 engine include:

  • Rear main seal
  • Timing belt
  • Oil leaks

We’ll discuss each of these Honda J32 issues throughout this article. However, it’s important we add some housekeeping notes before moving along. We may not say it every time, but we’re considering these problems among the most common. That doesn’t necessarily mean they’re common problems in the actual sense of the definition. Instead, when engine problems do occur these are a few of the most popular areas.

That said, Honda J-series engines have been around for a long time. The J32 is a solid, reliable engine that offers good longevity. Many of the issues we discuss aren’t true design flaws. It’s an older engine, though, and that can bring about a number of problems. We’ll circle back to the Honda J32 reliability topic at the end of the article. For now, let’s jump in and discuss the above common issues and failures.

1) J-Series J32 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.

Honda J32 Rear Main Seal Symptoms

Symptoms of rear main seal oil leak problems on the Honda/Acura J32 engine include:

  • Visible oil leak
  • Low engine oil
  • Burning oil smells

A visible oil leak is usually the only symptom of rear main seals on the Acura TL. If you’re noticing spots of oil on the driveway then the main seal is a likely culprit. Although, don’t just assume the J32 rear seal is to blame. Ensure you check the other basics like the oil pan, valve cover, etc.

Burning oil smells are possible, but it’s unlikely with a rear main seal leak. Smelling burning oil or seeing light smoke from the engine bay is more common with valve cover gaskets. Low oil is also a potential symptom. Chances are you’ll notice the puddle of oil long before low engine oil, though.

Acura Rear Main Seal Replacement

Book hours for main seal replacement can vary a bit by specific year and model. However, it’s common to receive quotes around 10-12 hours of labor to replace the rear main seal. Depending on labor rates in your area that’s a good $600-1,000+ in labor.

The Acura J32 seal itself can be found for less than $50, so it’s a cheap job for DIY’ers. Unless you’re experienced with working on cars we would recommend leaving this job to the pros.

2) Honda J32 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.

J32 3.2L V6 Timing Belt Symptoms

A few symptoms of a worn or failing timing belt on the Honda J32 V6 engine are:

  • Ticking or slapping sounds
  • Engine misfires
  • Engine light illuminated
  • Loss of power

Timing belt failure symptoms are often tough to detect before the belt actually snaps or slips. It’s a good idea to visually inspect the Acura J32 timing belt from time to time, especially towards the end of its useful life. Sometimes worn belts will make ticking or slapping like sounds from the engine.

Otherwise, the remaining J32 timing belt symptoms usually mean it has slipped or snapped. Misfires, power loss, engine lights, poor overall performance, and the engine shutting down are all possible when this occurs.

Honda J32 Timing Belt Replacement

The good news is that timing belt repairs aren’t too expensive. It’s standard maintenance so Honda designs these parts to not cost an arm and a leg. We do recommend replacing the belt and water pump together. They’re in the same area and this ensures you’re not paying double labor should the Honda J32 water pump fail.

As with any repair, prices vary depending on where you source parts and where you repair the car. Most 3.2L V6 timing belt & water pump kits should run under $200. Add in a few hours of labor for another $150-300. Of course, the DIY crowd can save on those expenses and moderate DIY’ers shouldn’t have much trouble.

3) Acura TL 3.2 V6 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.

Honda/Acura J32 Oil Leak Symptoms

Sorry for the repetitive nature of discussing general oil leaks after the rear main seals. Once again, symptoms of J32 oil leaks are pretty straight-forward. Nonetheless, look for the following signs of oil leaks on the Acura TL 3.2 V6:

  • Visible leak
  • Low oil
  • Burning oil smells
  • Smoke from engine bay

If you see noticeable oil spots then you likely have a leak somewhere. Again, low oil is a possible symptom but you should notice others before actually running low on oil. All engines consume some oil so low oil doesn’t always mean there’s a leak.

Burning oil smells and light smoke from the engine bay are common from valve cover leaks. This is likely the next most common Honda J32 leak – following the rear main seals. Valve covers lie at the top of the engine. Oil can often drip onto hot components like the exhaust manifold and burn off before reaching the ground. Look for any smoke from the engine bay or burning oil smells.

Honda 3.2 V6 Oil Leak Fix

Oil leaks aren’t all bad. They usually aren’t urgent repairs, but it’s still good to fix leaks as soon as possible. This is especially true if oil is leaking onto hot parts and posing potential fire hazards.

Anyways, the gaskets and seals responsible for J32 oil leaks are inexpensive parts. Labor can be the killer on the rear main seal, but most other leaks aren’t quite as bad. Still, expect $150-500 in labor and another $10-50 for parts – depending on the specific leak.

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 J32 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.

  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
