Lincoln Ls Engine Oil Drain Plugs

Lincoln Ls Engine oil drain plugs

Starting at $2.95, AutoBuffy stocks 13 engine oil drain plugs from Dorman and SKP to fit your Lincoln Ls. The drain plug seals the bottom of the oil pan, keeping engine oil from leaking out between changes. A worn or cross-threaded plug drips oil onto the ground, accelerates oil consumption, and can cause serious engine damage if ignored.

Signs your Lincoln Ls needs a new engine oil drain plug

  • Small but persistent oil puddle or drips appearing directly under the center-front of the vehicle after it has sat overnight
  • Visible oil seepage or wet residue around the drain plug head or on the oil pan near the plug
  • Oil level dropping between changes faster than normal with no other identified leak source
  • Drain plug feels loose, wobbles, or spins with little resistance when checked by hand
  • Stripped or damaged threads visible on the plug itself, or the plug required unusual force during the last oil change
  • Metallic smell of burning oil from underneath the vehicle caused by dripping oil contacting a hot exhaust component

Which engine oil drain plug should you buy for your Lincoln Ls?

The most important factors are thread size and pitch — a plug that does not match your Lincoln Ls's oil pan threads will not seal properly and can cause permanent thread damage. Beyond fitment, you should decide whether you want a standard reusable plug, a self-sealing design, or an oversized repair plug if the existing threads are already compromised.

OEM-specification standard plug
Best for
Routine replacement with undamaged oil pan threads
What you get
Exact thread size and pitch match; requires a new crush washer at each oil change for a proper seal
Magnetic drain plug
Best for
High-mileage engines or performance use
What you get
Same fitment as standard plus a magnetic tip that captures metallic wear particles suspended in the oil before they recirculate
Self-sealing / captive-washer plug
Best for
DIYers who change their own oil frequently
What you get
Integrated neoprene or nylon sealing ring that compresses on installation, eliminating the need to source a separate crush washer each time
Oversized repair plug (thread repair)
Best for
Oil pans with stripped or cross-threaded drain hole threads
What you get
Slightly larger outer diameter that cuts new threads into damaged pan material, restoring a leak-free seal without replacing the entire oil pan

Replacing the engine oil drain plug on a Lincoln Ls

Easy⏱ 15–30 minutesDrain panCorrect-size box-end wrench or socket and ratchetTorque wrenchJack stands or ramps (if additional clearance is needed)Clean shop rags

Warm the engine briefly to thin the oil, then drain the old oil completely before removing the plug for inspection. Thread the new or cleaned plug in by hand first to confirm it catches cleanly, then snug it down with a torque wrench to the specification listed in your Lincoln Ls's service manual — never rely on feel alone, as both under- and over-tightening cause leaks. Start the engine after refilling with oil and check around the plug for any seepage before lowering the vehicle.

Frequently asked questions

How much does it cost to replace engine oil drain plugs on a Lincoln Ls?
Parts alone start at $2.95 for a replacement drain plug for the Lincoln Ls. If you replace it yourself during a routine oil change the only additional cost is a new crush washer. Shop labor for drain plug replacement is typically minimal since the job is combined with an oil change service.
Can I reuse the engine oil drain plug on my Lincoln Ls?
The plug itself is reusable in most cases as long as the threads are clean and undamaged and the hex head shows no rounding. However, the crush washer or sealing washer must be replaced every time the plug is removed. Reusing a flattened crush washer is one of the most common causes of a dripping drain plug after an oil change.
What happens if I overtighten or cross-thread the drain plug on my Lincoln Ls?
Overtightening stretches the plug threads and deforms the oil pan threads, making a proper seal harder to achieve on future changes. Cross-threading shears the soft aluminum or steel pan threads outright. Both situations can result in a plug that will not torque down correctly and leaks, potentially requiring a thread repair kit or oil pan replacement.
How do I know what size drain plug my Lincoln Ls needs?
Drain plug thread size and pitch are determined by the engine and oil pan, not the body style. Check your owner's manual, the existing plug with a thread gauge, or enter your Lincoln Ls's year, make, and model in the AutoBuffy fitment filter. Common sizes vary widely, so confirming the exact spec before ordering prevents a return.
How often should the drain plug gasket or washer be replaced on a Lincoln Ls?
Replace the crush washer or sealing gasket every time the drain plug is removed — meaning at every oil change. Crush washers are single-use by design; they deform under torque to create the seal. Reusing one that has already been compressed reduces clamping force and is a leading cause of slow post-oil-change leaks on the Lincoln Ls.
Is a stripped drain plug thread on my Lincoln Ls an emergency?
A stripped drain plug that still seats but weeps oil is not an immediate breakdown risk, but it should be addressed before the next oil change. A plug that will not seat at all can fall out while driving, dumping all engine oil instantly and causing catastrophic engine failure within minutes. Do not drive the Lincoln Ls in that condition.
