Parts for your 2014 Honda Accord-Oil seals

2014 Honda Accord oil seals — what they do and when to replace

Oil seals are absolutely used on the 2014 Honda Accord. Honda’s factory service information for the 2013–2017 Accord (Honda Service Express/Helm Service Manual) includes procedures for front crankshaft oil seal, rear main seal, camshaft seals on the V6, and transmission/driveshaft oil seals. The Honda Electronic Parts Catalogue for the 2014 Accord likewise lists these seals across the 2.4‑litre four‑cylinder and 3.5‑litre V6, in CVT, 6‑speed automatic, and 6‑speed manual variants. So, yes — they’re relevant and they matter.

On this model, oil seals keep engine oil and transmission fluid where they belong, stop dirt and water sneaking in, and help maintain correct pressures for long component life. When they harden, wear a groove in the shaft, or get nicked during a belt/chain or transmission job, leaks start — sometimes as a light mist, sometimes as proper drips on the driveway.

• Engine: front crankshaft seal (behind the harmonic balancer), rear main seal (between engine and gearbox), and camshaft seals/plugs (notably on the V6).
• Transmissions: driveshaft/axle oil seals on CVT and 6‑speed auto, input/output shaft seals on the 6‑speed manual, intermediate shaft seal on the right‑hand side where fitted.

They’re not a scheduled replacement item, but they should be checked at every service. A quick look under the bonnet and underneath for fresh oil around the crank pulley, timing cover area, rear of the engine/bellhousing, or at the transaxle where the shafts enter can catch issues early. Identify the fluid: engine oil is usually amber/brown, 6‑speed auto ATF is red, and Honda CVT fluid is typically greenish — handy for tracing the culprit.

When replacement’s needed, using genuine or high‑quality seals is worth it. Clean the bore and shaft, lightly oil the seal lip, and install square with the correct driver. It’s smart to pair axle seal replacements, and to change a front crank seal while the harmonic balancer is off for other work. If there’s crankcase pressure from a blocked PCV system, fix that first or new seals may weep again.

Some jobs are tougher: a front crank seal needs the balancer off (special tool recommended on Hondas), while a rear main means gearbox removal — best left to experienced techs. After any seal work, top up the correct fluid (HCF‑2 for CVT, DW‑1 for 6‑speed auto, the specified engine oil) and recheck for leaks after a few hundred kilometres.

Popular questions about 2014 Honda Accord oil seals

Do all 2014 Accord engines have oil seals?
Yes. Every 2014 Accord uses multiple oil seals — front and rear crankshaft seals, camshaft seals or plugs (V6), plus transmission and driveshaft/axle seals across CVT, 6‑speed auto, and manual models.

What are the signs of a leaking oil seal on a 2014 Accord?
Oil mist or drips near the crank pulley or bellhousing, oil on the undertray, a burning‑oil smell, wetness where the driveshafts enter the gearbox, or low engine/trans fluid levels between services are common flags.

How much does seal replacement usually cost?
Ballpark figures (AU/NZ): front crank seal typically $300–$600 fitted, a single driveshaft/axle seal $200–$450, a rear main seal $1,000–$2,000 due to gearbox removal. Prices vary with engine/trans type and local labour rates.
