Acura Ilx Engine Oil Pump Chains

Acura Ilx Engine oil pump chains

Engine oil pump chains for your Acura Ilx start at low prices. We stock multiple options from top OE-quality brands. The oil pump chain drives the oil pump off the crankshaft, maintaining continuous lubrication pressure throughout the engine. A worn or broken chain can starve critical components of oil within seconds, leading to catastrophic engine damage.

Signs your Acura Ilx needs a new engine oil pump chain

  • Low or fluctuating oil pressure warning light illuminated at idle or under acceleration
  • Rattling or slapping noise from the front of the engine on cold starts that fades once oil pressure builds
  • Visible metal shavings or fine debris in the oil when performing an oil change
  • Engine oil pressure gauge reads abnormally low even after confirming correct oil level and fresh oil
  • Rough idle or engine hesitation caused by inconsistent oil delivery to the valvetrain and timing components
  • Oil pump chain tensioner failure code stored in the ECM, often paired with a check engine light on equipped vehicles

Which engine oil pump chain should you buy for your Acura Ilx?

The main decision is whether to match OE specification exactly or upgrade to a heavier-duty aftermarket chain. You also need to confirm whether your Acura Ilx uses a single-row or double-row chain, as these are not interchangeable. Buying a kit that includes the chain, sprockets, and tensioner together ensures all wear items are replaced at once and components are properly matched.

OE-Replacement Single-Row Chain
Best for
Stock engines with normal mileage being returned to factory spec
What you get
Direct-fit chain matching original pitch, width, and link count; straightforward installation with no modification
OE-Replacement Double-Row Chain
Best for
Engines originally equipped with double-row design or high-mileage rebuilds needing added durability
What you get
Wider, stronger chain with doubled link rows for greater tensile strength and resistance to stretch under load
Complete Oil Pump Chain Kit
Best for
Full engine rebuilds or any job where the tensioner and sprockets show wear alongside the chain
What you get
Chain, drive and driven sprockets, tensioner, and guides sold as a matched set; eliminates mismatched wear between components
Performance/Heavy-Duty Aftermarket Chain
Best for
Modified engines, forced-induction builds, or vehicles used in high-RPM or high-temperature conditions
What you get
Upgraded materials such as hardened steel links and precision-ground pins; tighter tolerances to resist stretch and maintain consistent oil pressure under stress

Replacing the engine oil pump chain on a Acura Ilx

Replacing the oil pump chain requires draining the oil, removing the oil pan, and in many cases pulling the front timing cover to gain access to the chain loop at the crankshaft snout. The new chain, sprockets, and tensioner are installed and the pump shaft is confirmed to be properly engaged before reassembly. All gaskets and seals disturbed during disassembly should be replaced, and the engine should be primed before first start to confirm oil pressure before cranking to run speed.

Frequently asked questions

How much does it cost to replace engine oil pump chains on a Acura Ilx?
Parts alone start at low prices for a Acura Ilx. Because the oil pump chain sits deep in the engine — typically behind the front cover — labor costs are substantial and often exceed the parts cost. Buying a complete kit with the tensioner and sprockets while the engine is already open avoids a costly second teardown.
Can I drive my Acura Ilx with a worn or noisy oil pump chain?
No. A worn oil pump chain should be treated as an immediate concern and not a deferred repair. If the chain skips teeth or breaks, the oil pump stops turning, oil pressure drops to zero, and bearing and valvetrain damage can occur within seconds of continued operation. Stop driving and diagnose the noise as soon as it appears.
How long does an engine oil pump chain last on a Acura Ilx?
Oil pump chains are designed to last the life of the engine under normal conditions, but real-world longevity depends heavily on oil change discipline. Extended intervals allow oil to degrade and lose lubricity, accelerating chain and tensioner wear. Engines with a history of infrequent oil changes or low oil level events are at significantly higher risk of early chain wear.
Should I replace the oil pump chain tensioner and sprockets at the same time?
Yes, always replace the tensioner and sprockets together with the chain. These components wear at the same rate and mate to each other over time. Installing a new chain on worn sprockets causes rapid re-wear of the new chain. A complete kit ensures matched tolerances and avoids returning to the same labor-intensive job prematurely.
Is replacing the engine oil pump chain on a Acura Ilx a DIY job?
It is an advanced job for most owners. Access requires draining the engine oil, removing the oil pan or front engine cover — and sometimes both — depending on how the Acura Ilx routes the chain. Proper timing of the chain to the crankshaft and pump is critical. Errors can result in immediate low oil pressure or engine damage on first start.
How do I know if my Acura Ilx has an oil pump chain versus a gear-driven oil pump?
Check your Acura Ilx service manual or the part fitment data on this page. Engines with chain-driven oil pumps typically show a dedicated small chain loop at the front of the crankshaft separate from the timing chain. Gear-driven pumps have no chain at all. Fitment listings for the Acura Ilx will confirm which system your specific engine uses.
